Answer:
See all four answers with their explanation below and the graph attached.The green arrow on the number line is the solution of the inequality.Explanation:
a). Description of what Brian did wrong.
Brian did not solve the inequality correctly. It seems he made several wrong steps:
He added up 2 and 3 to get 5, which is wrong because 2 and 3 are in opposite sides of the inequalityHe use the symbol <, which is wrong because there is a negative sing in front of the varialbe (x) which changes the symbol to >.b). Your work solving the inequality:
Subtract 2 from both sides:- x < 3 - 2
-x < 1
Muliply both sides by - 1, which changes the symbol < to >:x > - 1
Then the solution of the inequality is all the real numbers greater than - 1.
c). The correct solution graphed on a number line
Since the number - 1 is not included in the solution set of the inequality you must use an oper circle around the number - 1 on the number line.Since the solution set is all the numbers greater than - 1 you draw an arrow pointing to the right of the number - 1 on the number line.See the correct graph in the diagram attached. The green line on the number line is the solution to the inequality.d). The correct solution in set notation.
Three valid forms indicating the solution in set notation are:
{x: > - 1}, which is read x such that x is greater than - 1{x | x > - 1}, which is read x such that x is greater than - 1{x ∈ R | x > - 1}, which is read, x belonging to real numbers, such that x is greater than - 1.Both the colon (:) and the straight bar (|) mean "such that".

How is volume calculated given mass and density? (1 point) Question 8 options: 1) Sum of mass and density 2) Mass divided by density 3) Mass multiplied by density 4) Difference of mass and density
Answers
Answer:
Option 2. Mass divided by density
Step-by-step explanation:
we know that
The formula to calculate the density is equal to
[tex]D=\frac{m}{V}[/tex]
where
D is the density
m is the mass
V is the volume
Solve for V (that means isolate the variable V)
Multiply both sides for V
[tex]DV=m[/tex]
Divide by D both sides
[tex]V=\frac{m}{D}[/tex]

Mitch has already spent 26 minutes on the phone, and he expects to spend 2 more minutes with every phone call he routes. Write the relationship between the phone calls routed p and the minutes on the phone t.
Answers
Answer:
minutes spent on phone (t) is directly proportional to the phone calls routed (p) with equation [tex]t =26+2p[/tex].
Step-by-step explanation:
Given:
Number of minutes already spent = 26 minutes
Number of minutes expected to spend on each call = 2
Let number of calls routed be 'p'
Also Let number of minutes on the phone be 't'.
We need to find the relationship between phone calls routed and mins spend on the phone.
Solution:
Now we know that;
Total minutes spent on phone is equal to Number of minutes already spent plus Number of minutes expected to spend on each call routes multiplied by number of calls routed.
framing in equation form we get;
[tex]t =26+2p[/tex]
From above we can see that whenever p increases the value of t will increase too .
Hence we can say that minutes spent on phone (t) is directly proportional to the phone calls routed (p) with equation [tex]t =26+2p[/tex].
There are 6 showings of a film about Van Gogh at the art museum. A total of 459 people saw the film. The same number of people were at the showing. About how many people were at the showing ? Circle the numbers the quotient is between
Answers
Final answer:
About 76 or 77 people were at each showing of the Van Gogh film at the art museum.
Explanation:
The student's question asks about dividing the total attendance at a film showing into equal parts to find out how many people were at each showing. To solve this, we would take the total number of attendees, which is 459, and divide it by the number of showings, which is 6. This division is necessary to distribute the total equally among all showings.
Performing the division: 459 ÷ 6 = 76.5. Since you cannot have half a person attending, it suggests that the number of attendees per showing must either be rounded to 76 or 77, if we are dealing with whole numbers. However, since the exact division gives us 76.5, this suggests that the division of attendees was not perfectly even among all showings or requires rounding for an approximate answer.
Therefore, about 76 or 77 people were at each showing of the Van Gogh film at the art museum.
Rosita earns money by walking dogs after school and on weekends.She walks Madeline every other day,buddy every fourth day,and ernie every third day.Today she walked all three dogs. What day did she walk all three dogs?
Answers
On 12th day Rosita will walk all three dogs
Solution:
Given that Rosita earns money by walking dogs after school and on weekends
She walks Madeline every other day,buddy every fourth day,and ernie every third day
Today she walked all three dogs
To find: the day when she walked all three dogs
From given question,
Madeline is walked every other day means every two days: 2
Buddy is walked every fourth day: 4
Ernie is walked every third day: 3
To find the day when she walked all three dogs, we have to find the least common multiple (LCM) of 2, 4, 3
L.C.M of 2, 4, 3:
List all prime factors for each number
Prime Factorization of 2 shows:
2 is prime => [tex]2^1[/tex]
Prime Factorization of 3 shows:
3 is prime => [tex]3^1[/tex]
Prime Factorization of 4 is:
[tex]2 \times 2 = 2^2[/tex]
For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.
The new superset list is
2, 2, 3
Multiply these factors together to find the LCM.
LCM = 2 x 2 x 3 = 12
Thus on 12th day Rosita will walk all three dogs
Nour and Rana are shopping for a Christmas tree. They are deciding between 2 different types of trees (real and fake) and 4 colors for the ornaments (white, silver, gold, and purple). They each created a display to represent the sample space of randomly picking a type of tree and a color for the ornaments.
Answers
There are no actual questions provided for this post. However, based on the details given, the question will probably asked about the following:
a) list the sample space
b) the probability of having a type of tree with certain color
I will explain to you how to answer such questions. Though it may defer a bit from the actual question, you could use guidance to provide the basis for your answer.
Answer and Step-by-step explanation:
List of sample space must incorporate each sample on two different events given that both events are independent to each other.
In this case we have two events:
i) type of tree - real or fake
ii) color of ornaments - white (W), silver (S), gold (G) or purple (P)
Each sample must have one choices of each events. In this case the sample space are:
(real,W), (real,S), (real,G),(real,P)
(fake,W), (fake,S), (fake,G), (fake,P)
To find probability of any choices, we need to know the probability of each samples. Assuming the selection is random and both events are independent to each other, we can have each sample for each event having different probability.
Event: type of tree
Number of choice: 2
Hence, Pr(real) = Pr(fake) = 1/2
Event: ornament color
Number of choices: 4
Hence, Pr(W) = Pr(S) = Pr(G) = Pr(P) = 1/4
To find the probability of any sample space, we can base our probability using individual probability as above.
For example, if the choice is fake tree with red ornaments
Pr(fake & R) = Pr(fake) x Pr(R)
= 1/2 x 1/4
= 1/8

It takes 2 minutes to print out 3 photos. Write an equation relating the number of photos N to the number of minutes M. At this rate, how long will it take to print 10 photos? 14 photos?
Answers
Answer:
Part a) [tex]M=6\frac{2}{3}\ min[/tex]
Part b) [tex]M=9\frac{1}{3}\ min[/tex]
Step-by-step explanation:
we know that
A relationship between two variables, M, and N, represent a proportional variation if it can be expressed in the form [tex]k=\frac{N}{M}[/tex] or [tex]N=kM[/tex]
In this problem, the relationship between the number of photos N to the number of minutes M represent a proportional variation
we have that
For M=2, N=3
Find the the constant of proportionality k
[tex]k=\frac{N}{M}[/tex]
substitute the value of N and M
[tex]k=\frac{3}{2}[/tex]
so
[tex]N=\frac{3}{2}M[/tex]
Part a) How long will it take to print 10 photos?
For N=10
substitute in the linear equation
[tex]10=\frac{3}{2}M[/tex]
solve for M
[tex]M=\frac{10*2}{3}[/tex]
[tex]M=\frac{20}{3}\ min[/tex]
Convert to mixed number
[tex]M=\frac{20}{3}\ min=\frac{18}{3}+\frac{2}{3}=6\frac{2}{3}\ min[/tex]
Part b) How long will it take to print 14 photos?
For N=14
substitute in the linear equation
[tex]14=\frac{3}{2}M[/tex]
solve for M
[tex]M=\frac{14*2}{3}[/tex]
[tex]M=\frac{28}{3}\ min[/tex]
Convert to mixed number
[tex]M=\frac{28}{3}\ min=\frac{27}{3}+\frac{1}{3}=9\frac{1}{3}\ min[/tex]

answer choices :
(A) 180 feet
(B) 250 feet
(C) 540 feet
(D) 750 feet
Answers
Answer:
C
Step-by-step explanation:
We need to find the length of the red dotted line.
It is divided into 3 parts: the top, the middle slant, and the bottom
The top
Goes from y = 50 to y = 120, the length is:
120 - 50 = 70 units
The bottom
Goes from x = 60 to x = 120, the length is:
120 - 60 = 60 units
The middle slant
This is hypotenuse of the right triangle shown.
We will use Pythagorean Theorem to solve for this length, let it be x.
The theorem is:
Leg^2 + Another Leg^2 = x^2
One leg goes from x = 20 to x = 60, the length is 60 - 20 = 40
Another leg goes from y = 20 to y = 50, the lenth is 50 - 20 = 30
So, we have:
[tex]30^2+40^2=x^2\\2500=x^2\\x=\sqrt{2500}\\x=50[/tex]
THe slant length is 50 units
TOtal fencing is: 70 + 60 + 50 = 180 units
1 unit is 3 feet, so
180 units * 3 = 540 feet
C is the correct answer

==================================
Explanation:
Mark point D as the center of the circle. Segment EG is the diameter, so angle EDG is 180 degrees. By the central angle theorem, arc EFG is also 180 degrees.
The minor arc from E to F (follow the shortest path along the circle) is 56 degrees. From F to G, along the shortest path, we have y degrees.
(minor arc EF)+(minor arc FG) = arc EFG
56+y = 180
56+y-56 = 180-56
y = 180-56
y = 124
Minor arc FG is 124 degrees.
This is equivalent to saying that central angle FDG is 124 degrees.
-----------------
The inscribed angle for minor arc FG is the angle FEG, which is half that of the minor arc measure.
inscribed angle = (1/2)*(arc measure)
angle FEG = (1/2)*(minor arc FG)
x = (1/2)*(124)
x = 62
Good evening ,
Answer:
x = 62°
Step-by-step explanation:
x equals to half the measure of the central angle FOG
x = (1/2)×(m∠FOG)
m∠FOG = 180 - m∠EOF
= 180 - 56
= 124
then x = 124/2 = 62.

A line is parallel to y = 4x + 1 and intersects the point (-2, -5) What is the equation of this parallel line?
Answers
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
y= 4x + 1
Comparing with the slope intercept form, slope = 4
If two lines are parallel, it means that they have the same slope. Therefore, the slope of the line passing through (-2, - 5) is 4
To determine the intercept, we would substitute m = 4, x = - 2 and y = -5 into y = mx + c. It becomes
- 5 = 4 × - 2 + c = - 8 + c
c = - 5 + 8 = 3
The equation becomes
y = 4x + 3
Answer:
Step-by-step explanation:
any eq. of line parallel to y=4x+1 is
y=4x+a

Work Shown:
Through the inscribed angle theorem, we can say that 2 times the inscribed angle gets us the arc that the inscribed angle cuts off.
2*(inscribed angle) = arc measure
2*(2x+2) = 76
4x+4 = 76
4x+4-4 = 76-4 ... subtract 4 from both sides
4x = 72
4x/4 = 72/4 ... divide both sides by 4
x = 18
Answer:
Step-by-step explanation:
2 × inscribed angle = 76
2 × (2x + 2) = 76
Open bracket
4x + 4 = 76
Collect like terms
4x = 76 - 4
4x = 72
Divide both sides by 4
4x/4 = 72/4
X = 18
Therefore X is Equal to 18.
James and Lucas competed in climbing a mountain and coming back. James climbed at an average rate of 3 mph and ran back at 4 mph. Lucas climbed at an average rate of 2 mph and ran back at 5 mph. If the path from the bottom to the top of the mountain was 2 miles, how much time did each take to finish and who was faster?
Answers
Answer:Lucas is faster
Step-by-step explanation:
Distance = speed × time
Time = distance × speed
the path from the bottom to the top of the mountain was 2 miles.
James climbed at an average rate of 3 mph. This means that the time it took James to climb to the top of the mountain would be
2/3 hours
James ran back at 4 mph. This means that the time it took James run back to the bottom of the mountain would be
2/4 = 1/2 hours
Total time that James spent would be
2/3 + 1/2 = 7/6 = 1.7 hours.
Lucas climbed at an average rate of 2 mph. This means that the time it took Lucas to climb to the top of the mountain would be
2/2 = 1 hour
Lucas ran back at 5 mph. This means that the time it took Lucas to run back to the bottom of the mountain would be
2/5 hours
Total time that James spent would be
1 + 2/5 = 1.4hours.
Answer:
James is faster
Step-by-step explanation:
It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.
Step-by-step explanation:
Keep in mind that Distance = Speed * Time
First lets starts off with James,
Climbing rate of James = 3 mph
Running back rate of James = 4 mph
Total time taken by James = 3/4 x 2/4 = 14/12 = 7/6
Lets convert that into min to make it easier,
7/6 x 60 = 70 min
Now, lets look at lucas,
Climbing rate of Lucas = 2/2 = 1 hour(s) or 60 minutes
Climbing back rate of Lucas = 2/5 of an hour
Now lets convert this one into minutes,
2/5 x 60 = 24 minutes
Total time taken by Lucas = 24 + 60 = 84 minutes
so that means
James = 70 minutes
Lucas = 84 minutes
Therefore James was faster

Sonia bought 30 t shirts at a clothing store. 20% of the t shirts were blue and 1/2 of the t shirts were black. How many of the t shirts were neither black or blue?
Answers
9 T-Shirts
Step-by-step explanation: There are 30 t shirts. 20% of the t shirts were blue and 1/2 of the t shirts were black. 20% is equivalent/ the same as 20/100 and simplified, 1/5. 1/2 black + 1/5 blue = 70/100 black and blue. This leaves 30/100(30%) remaining t shirts (neither black or blue). This leaves us to find 30% of 30 (shirts). 30% of 30 equals 9. 30/100 = 9/30.Final answer:
To find the number of t-shirts that were neither black nor blue, subtract the number of black and blue t-shirts from the total. In this case, there were 9 t-shirts that were neither black nor blue.
Explanation:
To find the number of t-shirts that were neither black nor blue, we need to subtract the number of black and blue t-shirts from the total number of t-shirts.
20% of the t-shirts were blue, which means there were 30 x 0.20 = 6 blue t-shirts.
1/2 of the t-shirts were black, which means there were 30 x (1/2) = 15 black t-shirts.
Now, to find the number of t-shirts that were neither black nor blue, we subtract the number of black and blue t-shirts from the total number of t-shirts:
Total number of t-shirts - (Number of black t-shirts + Number of blue t-shirts) = 30 - (15 + 6) = 30 - 21 = 9.
Therefore, there were 9 t-shirts that were neither black nor blue.

Marge bought a computer for $699 on the installment plan. The terms of the plan were a down payment of $100, then payments of $58 a month for 12 months. How much was her total cost?
Answers
Answer:
$796
Step-by-step explanation:
We have been given that Marge bought a computer for $699 on the installment plan. The terms of the plan were a down payment of $100, then payments of $58 a month for 12 months.
First of all, we will find the amount paid in 12 months by multiplying $58 by 12 as:
[tex]\text{Amount paid in 12 months}=\$58\times 12[/tex]
[tex]\text{Amount paid in 12 months}=\$696[/tex]
Since Marge paid $100 as down payment, so her total cost would be down payment plus amount paid in 12 months.
[tex]\text{Marge's total cost}=\$100+\$696[/tex]
[tex]\text{Marge's total cost}=\$796[/tex]
Therefore, Marge's total cost was $796.

Jamie bought a soda for $3. He also bought some corn dogs for $4 each. Jamie did not spend more than $27 on the corn dogs and the soda. Which inequality can be used to find h, the number of corn dogs that Jamie could have bought?
Answers
Answer:
The number of corn dogs bought is 3.
Step-by-step explanation:
It is given that, cost of soda is $3 and cost of corn dogs is $4 each.
Let the number of soda bought be "x" and corn dogs be "y".
Thus the total amount spent is given by,
[tex]A = 3x + 4y[/tex]
The total amount is less than or equal to $27, which means;
[tex]3x+4y\leq 27[/tex]
The above inequality can be used to find the number of corn dogs bought.
[tex]y\leq \frac{27-3x}{4}[/tex]
Now, number of items bought are greater than zero and integers, thus x and y are greater than zero integers.
Inserting x from 0 to 9, we get only two only 2 answers,
(x,y) = (5,3) and (9,0)
But it is said that number of corn dogs is not zero, some are bought, thus correct solution is (5,3).
Thus the number of corn dogs bought is 3.

Answers
Answer:
Step-by-step explanation:
1) The sum of angles on a straight line is 180 degrees. Therefore
75 + a + 70 = 180
145 + a = 180
a = 180 - 145 = 35 degrees
2) Sum of the angles in a triangle is 180 degrees. Therefore,
a + b + 95 = 180
35 + b + 95 = 180
130 + b = 180
b = 180 - 130 = 50 degrees
3) c + 95 = 180 degrees (sum of angles on a straight line).
c = 180 - 95 = 85 degrees
4) 70 + c + d = 180 degrees
70 + 85 + d = 180
155 + d = 180
d = 180 - 155 = 25 degrees
5) e = 75 degrees
6) f + e + 75 = 180 degrees
f + 75 + 75 = 180
f + 150 = 180
f = 180 - 150 = 30 degrees

Hope this helps!
Sometimes a trigonometric equation is written in quadratic form. This means that you can solve the equation the same way you would solve a standard quadratic equation. For example, the equation: sin2 2.5x − 4 sin 2.5x − 5 = 0 can be considered to be like the form x 2 − 4x − 5 = 0. Use this fact to solve this trigonometric equation on the interval 0 ≤ x < 2π.

Answer:
108 degrees
Step-by-step explanation:
To solve this adequately, we simply make a substitution. We can say let sin2.5x = x
Hence we can thus have the quadratic equation form which we can solve.
x ^2 − 4x − 5 = 0.
Solving this yields the following:
x^2 +x - 5x -5 = 0
x( x + 1) -5(x + 1) = 0
(x - 5) (x + 1) = 0
x = 5 or -1
Recall the substitution:
sin2.5x = x
We cannot use the value -5 as the value of the sine function cannot be in this range. We thus ignore it and pick the -1 answer only.
Sin2.5x = -1
2.5x = arcsin(-1) = 270
2.5x = 270
x = 270/2.5 = 108 degrees

Answers
Answer: the second option is the correct answer
Step-by-step explanation:
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the information on the graph y2 = - 1
y1 = - 2
x2 = 4
x1 = 0
Slope = ( - 2 - - 1)/(4 - 0) = - 1/4
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
To find the slope of a line we need two points through which it is passing.
From the figure, we can see that the line passes through (0,-2) and (4,-1).
Slope of a line passing through two points [tex](x_{1},y_{1})\ and\ (x_{2},y_{2})[/tex] is given by the formula:
[tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Here x1=0 y1=-2 x2=4 y2=-1
Slope = [tex]\frac{-1-(-2)}{4-0}=\frac{1}{4}[/tex]
Hence the slope of the line is [tex]\frac{1}{4}[/tex]
A collection of numerical information, such as the scores on a test, is referred to as simple random sampling.True / False.
Answers
Answer:
False. See explanation below.
Step-by-step explanation:
False
A simple random sample "is a subset of a statistical population in which each member of the subset has an equal probability of being chosen"
In other words that means in order to apply a random sampling we need to ensure that we have the same probability of inclusion for every possible element of the population of interest.
And for this case a collection of any numerical information is not referred as random sampling since we don't know if these scores are representative of the population of interest.
And we don't know if this information is obtained using any sampling frame or sampling methodology.
