Myra's test scores are shown. She has one more test for the semester. What is the minimum score that she can make on her last test and have an average greater than 90?
Note: All scores are whole numbers and scores are not rounded
a. 95
b.96
c.97
d.98
Answers
Answer:
Option: d is the correct answer.
d. 98
Step-by-step explanation:
The scores of Myra's test are as follows:
84, 99, 88, 82, 95, 85
Let 'x' be the minimum score that is obtained by Myra in the last test so that the average is greater than 90 marks.
i.e.
[tex]\dfrac{84+99+88+82+95+85+x}{7}>90\\\\\\i.e.\\\\\\\dfrac{533+x}{7}>90\\\\\\i.e.\\\\\\533+x=90\times 7\\\\\\533+x>630\\\\\\x>630-533\\\\\\x>97[/tex]
Hence, the minimum score has to be 98.
( Since, the scores are in whole number )

number of different 5 digit combinations if successive digits msut be different
Answers
For each next digit you can't choose the same digit, so you have 9 options.
So number of combinations is 10*9*9*9*9 = 65610
The permutations formula is applied to determine the number of different 5-digit combinations where successive digits must be different, resulting in a total of 30,240 combinations.
Permutations are used when the order of elements matters. In this case, the number of different 5-digit combinations where successive digits must be different can be calculated using the permutations formula.
Identify that we need to use permutations due to the order of elements being important.Calculate the number of possibilities for each digit decreasing by 1 with each selection. For a 5-digit number, it would be 10 choices for the first digit, 9 for the second, 8 for the third, 7 for the fourth, and 6 for the fifth.Calculate the total number of combinations by multiplying the number of choices for each digit together: 10 x 9 x 8 x 7 x 6 = 30,240.Lines AB and EB share a common point at B therefore we say that these lines

For stock B, the equation is y=16.04-0.09x where x is the number of hours.
We're trying to find when they will be equal.
15.54+0.11x=16.04-0.09x
1554+11x=1604-9x
1554+20x=1604
20x=50
x=2.5
Final answer: About 2.5 hours
let number of hours = x
1st equation is 15.54+0.11x
2nd equation is 16.14-0.09x
now calulate x so the 2 equations are equal:
15.54+0.11x=16.04-0.09x
mutiply evrything by 100 to get rid of the decimal points andmake the calculations a little easier
1554+11x=1604-9x
add 9 x to both sides:
1554+20x=1604
subtract 1554 from both sides:
20x=50
divide 50 by 20 for x
x=50/20 = 2.5
x = 2.5
so they were the same after 2.5 hours

Step-by-step explanation:
To estimate the local maximum and local minimum using graph.
Local maximum: It is largest value of function for all other values of function near by.
Local minimum: It is smallest value of function for all other values of function near by.
A function has two extrema maxima or minima.

A rectangle has a perimeter of 16 inches.
What dimensions (length, width) could be the dimensions of the sides?
A. (8, 0)
B. (2, 12)
C. (6, 2)
D. (13, 3)
E. (3, 10)
Answers
option C: (6, 2).
The student has asked for the possible dimensions of a rectangle given that its perimeter is 16 inches. To find the dimensions that are correct, we need to remember that the perimeter of a rectangle is calculated by the formula P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. We must check each pair of dimensions provided and see if they satisfy this equation when the perimeter is 16 inches.
A. (8, 0) - This would give us a perimeter of 2(8) + 2(0) = 16 inches, which is correct, but it is not a possible dimension for a rectangle, as having a side of length 0 inches does not make a rectangle.B. (2, 12) - The perimeter here would be 2(2) + 2(12) = 28 inches, which is not equal to 16 inches.C. (6, 2) - Checking this option, we get 2(6) + 2(2) = 12 + 4 = 16 inches. This one is correct and is a possible dimension for a rectangle.D. (13, 3) - The perimeter in this case would be 2(13) + 2(3) = 26 + 6 = 32 inches, clearly more than 16 inches.E. (3, 10) - This would give us a perimeter of 2(3) + 2(10) = 6 + 20 = 26 inches, which also does not equal the 16-inch perimeter required.Therefore, the only possible dimensions for the rectangle given the choices provided and where both dimensions are greater than zero is option C: (6, 2).

Answer:
The correct option is 2.
Step-by-step explanation:
The formula form speed is
[tex]speed=\frac{distance}{time}[/tex]
[tex]time=\frac{distance}{speed}[/tex]
It is given that the school is 16 miles from his home. He averages 40 miles per hour on his way to school. Time taken by Aidan to reach school from the home is
[tex]t_1=\frac{16}{40}[/tex]
Let speed at which Aidan drive home be s. Time taken by Aidan to reach home from the school is
[tex]t_2=\frac{16}{s}[/tex]
It is given that his total trip takes 1 hour.
[tex]\frac{16}{40}+\frac{16}{s}=1[/tex]
[tex]\frac{16s+640}{40s}=1[/tex]
[tex]16s+640=40s[/tex]
[tex]640=40s-16s[/tex]
[tex]640=14s[/tex]
Divide both sides by 14.
[tex]\frac{640}{24}=s[/tex]
[tex]s=26.666667[/tex]
[tex]s\approx 27[/tex]

If Susan subtracts 11 from one-fourth of her number she gets 11
Answers
Final answer:
Susan's number is found by solving the equation x/4 - 11 = 11, which after isolating the variable and multiplying both sides by 4 yields the answer x = 88.
Explanation:
If Susan subtracts 11 from one-fourth of her number, she gets 11. To solve this problem, we set up an equation where x represents Susan's number. The one-fourth of her number would be x/4, and subtracting 11 from one-fourth of her number yields: x/4 - 11 = 11.
To find x, we first isolate the variable on one side by adding 11 to both sides of the equation, so we have x/4 = 22. Next, we multiply both sides by 4 to solve for x: x = 22 * 4. Therefore, Susan's number is 88.

what is y=-3x+4 and y=3x-2
by using transitive property
Answers
We can flip an equation to have it mean the same thing. Example: x = 5 is the same as 5 = x
The transitive property is the idea where if a = b and b = c, then a = c. Think of it as connecting a chain. Or taking a shortcut. If we know a leads to b, and b leads to c, then we can skip b all together and go from a directly to c.
Same idea applies here: we have -3x+4 equal to y, and y also equal to 3x-2 so -3x+4 = 3x-2
y-(3 times X) + 2=0
3 times X+y-4=0\ -3 times X -4
y= -(3 times X-4
y=4-(3 times X)
2-( 3 times X)- (3 times X)+4=0
y=4-(3 times X)
6-6 times X =0 \-6
-6 times X= -6 \ : -6
X= -6\(-6) X=1
y=4 - (3 times 1)
y=4-3
The answer is y=1

Answers
Answer: There are 220 employees working now.
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the number of employees by the percentage in decimal form.
12% = 12/100= 0.12 (decimal form)So, mathematically speaking:
250 x 0.12 = 30 employees lessFinally, we subtract the number obtained to the initial number of employees.
250 -30 = 220 employees.There are 220 employees working now.

It would take 20 sessions to break even on what she spends for the snow blower.
The cost of the snow blower is $689, hence:
Cost = $689
Let x represent the number of sessions, Since $35 is paid to clear the driveway, hence:
Revenue = 35x
At breakeven:
Cost = Revenue
35x = 689
x = 20 (to nearest whole number)
Hence it would take 20 sessions to break even on what she spends for the snow blower.
