Answer:

Slope is 5, y-int is 1, and f(n) = 5n+1

Step-by-step explanation:

So, since we are dealing with an arithmetic sequence, it is linear. If you notice, it is just adding 5 from the previous term. This represents a slope of 5. Increase of 1 in x and increase of 5 in y. Then, f(1) = 6. Since 1 x 5 is 5, and 5 + 1 = 6, the b is 1. This is because the normal 5x is deviated by 1. Since it is arithmetic, that 1 unit deviation will carry on. The last question basically says just write the y=mx + b but just use n and f(n), which is f(n) = 5n + 1.

Final answer:

In a classroom with 12% left-handed students, the fraction representing them is 3/25 after simplification, and with 88% right-handed students, their fraction is 22/25. Since 22/25 is greater than 3/25, there are more right-handed students.

Explanation:

If 12% of the students in your class are left-handed, the fraction of students that are left-handed is 12/100, which can be simplified to 3/25 by dividing both the numerator and the denominator by 4. There are clearly more right-handed students because if 12% are left-handed, then 100% - 12% = 88% are right-handed. The fraction of right-handed students is 88/100, which simplifies to 22/25. Comparing the two fractions, 3/25 for left-handed students and 22/25 for right-handed students, it’s evident that there are more right-handed students in your class.

Answer:

512 student tickets.

Step-by-step explanation:

Let x be number of student tickets and y be number of adult tickets.

We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:

[tex]x+y=1294...(1)[/tex]

We are also told that each student ticket costs $5.00, and each adult ticket costs $8.00 and 1,294 tickets were sold for a total amount of $8,816. We can represent this information as:

[tex]5x+8y=8,816...(2)[/tex]

From equation (1) we will get,

[tex]y=1294-x[/tex]

Substituting this value in equation (2) we will get,

[tex]5x+8(1294-x)=8,816[/tex]

[tex]5x+10352-8x=8,816[/tex]

[tex]-3x+10352=8,816[/tex]

[tex]-3x=8,816-10352[/tex]

[tex]-3x=-1536[/tex]

[tex]x=\frac{-1536}{-3}[/tex]

[tex]x=512[/tex]

Therefore, 512 student tickets were purchased at Fridays football game.

Answer:

JL = 70

Step-by-step explanation:

If K is the midpoint of the segment, then JK = KL

JK = KL

9x-1 = 2x+27

Subtract 2x from each side

9x-2x -1 = 2x+27-2x

7x-1 = 27

Add 1 to each side

7x-1+1 = 27+1

7x = 28

Divide each side by 7

7x/7 = 28/7

x =4

But we want to find JL

JL = JK + KL

JL = 9x-1 +2x+27

Combine like terms

JL =  11 x+ 26

Substitute x =4

JL = 11*4+26

JL = 44+26

JL = 70

The length of line segment JL, when K is its midpoint and given jk = 9x - 41 and kl = 2x + 27, is 70.

This question is related to geometry and specifically the section on line segments. Firstly, if K is the midpoint of line segment JL, that means JK and KL are of equal lengths. So, we can set their equations equal to each other:

9x - 1 = 2x + 27

To solve this equation, start by subtracting 2x from both sides to isolate the variable x on one side:

7x - 1 = 27

Next, add 1 to both sides:

7x = 28

Dividing both sides by 7 gives:

x = 4

Substitute x = 4 into either of the equations, say kl = 2x + 27, gives the length of segment KL as:

kl = 2(4) + 27 = 35

The length of JL would then be twice the length of KL (since K is the midpoint) so:

jl = 2 * 35 = 70.

The square of a whole number between 4500 and 4900 must be between 67 and 69, hence the number is in the range of 65 to 70 excluding 70.

The student's question involves finding the whole number whose square falls between 4500 and 4900. To solve for the range of whole numbers, we need to take the square root of both limits. Since the square root of 4500 is approximately 67.08 (rounded down to the nearest whole number is 67) and the square root of 4900 is exactly 70, the whole number must be between 67 and 70. However, since 70 squared gives us 4900, we exclude it from the possible numbers. Therefore, the possible numbers are 67, 68, and 69, which means the correct answer is between 65 and 70.

Answer:

77 is a composite number

Step-by-step explanation:

41 = 1 × 41

77 = 1 × 77 = 7 × 11

83 = 1 × 83

89 = 1 × 89

97 = 1 × 97

Answer:

Step-by-step explanation:I would say 77.The reason is because a composite number is where it has a multiple more than just itself or 1.So what you can do is write the multiples of each number.Then once you do that you can easily tell which numbers are composite and prime numbers.Remember prime numbers are numbers that just have a multiple of one and itself.

Answer:

g=4

Step-by-step explanation:

If you're solving for g, you need to get it alone on one side. The way I did so was to subtract 7 from each side.

15 = 2g + 7

-7            -7

If you do that, the 7 on the right cancels out and you're left with 8 = 2g. To get the g alone, you divide it by it's base on both sides which in this case is 2.

8/2 = 2g/2

That will cancel the 2 out and will leave you with g on the right side and on the left side would be 4 because simple division (8/2=4)

Your final answer should be g = 4

Thirty-four thousandths.

Answer:

18 feet

Step-by-step explanation:

Let the height be x

We are given that The side lengths of the state flag of Colorado are in the ratio 2:3.

Length: Height = 2:3

Length of the flag is 12 feet long

Length : Height = 12:x

So, ATQ

2:3::12:x

[tex]\frac{2}{3}=\frac{12}{x}[/tex]

[tex]x=\frac{12 \times 3}{2}[/tex]

[tex]x=18[/tex]

Hence it’s height is 18 feet

To find the height of the Colorado state flag, we can use the given ratio of side lengths and solve for the unknown height using a proportion.

To find the height of the Colorado state flag, we can use the given ratio of side lengths – 2:3. Since the given length is 12 feet, we can set up the ratio equation as follows:

2/3 = 12/x

To solve for x, we can cross multiply:

2x = 3 * 12

Simplifying further, we get:

2x = 36

Dividing both sides by 2, we find that:

x = 18

Therefore, the height of the Colorado state flag is 18 feet.

Answer:

The heights of subjects in a clinical trial of a new drug is a quantitative data.

Step-by-step explanation:

Qualitative: If a data represents characteristics, color, quality and it is non-numerical in nature, then it is known as qualitative data.

Quantitative: If a data represents numerical values, then it is known as qualitative data.

For example:- height, weight, age, etc.

The heights of subjects in a clinical trial of a new drug can be represented by numerical values.

Therefore the heights of subjects in a clinical trial of a new drug is a quantitative data.

Final answer:

To convert the fraction 12/(y-x) to have a denominator of (x-y), you multiply both numerator and denominator by -1, resulting in the fraction -12/(x-y).

Explanation:

To bring the fraction 12/(y−x) to a denominator of (x−y), realize that y−x is essentially -(x−y). This means we can multiply the numerator and denominator by -1 to get the desired denominator. The step-by-step process would be:

Now, the fraction 12/(y−x) is expressed with the desired denominator (x−y) as -12/(x−y).

Answer:

6.32 cm.

Step-by-step explanation:

We can see that the given glass is in form of a cone.

To find the height of liquid in glass we will use formula:

[tex]h=\sqrt{l^2-r^2}[/tex], where,

h= Height of cone.

l= Slant height of cone.

r= Radius of cone.

We can see from our figure that diameter of cone is 6 cm, so radius of cone will be half of 6 cm, that is 3 cm.

We have been given slant height equals to 7 cm.

Let us substitute our values in above formula to find the height of liquid in the glass.

[tex]\text{Height of liquid in the glass}=\sqrt{7^2-3^2}[/tex]

[tex]\text{Height of liquid in the glass}=\sqrt{49-9}[/tex]

[tex]\text{Height of liquid in the glass}=\sqrt{40}[/tex]

[tex]\text{Height of liquid in the glass}=6.3245553203367587\approx 6.32[/tex]

Therefore, the height of liquid in the glass is 6.32 cm.

Answer:

The expressions are not equivalent.

Step-by-step explanation:

Three-tenths of the total volume, v = [tex]\frac{3}{10} (v)[/tex]

= 0.3 × v --- (1)

But, 310x is 310 × v --- (2)

Since (1) and (2) represent the same volume,

0.3 × v = 310 × v

Divide both sides by v,

0.3 = 310 which is a contradiction.

Therefore, the expressions are not equivalent.

Answer:

c is approximately  11.66 units

Step-by-step explanation:

Point E is at coordinates (-3,  5)

Point D is at coordinates (3 ,-5)

 Making a right triangle

 The x distance is  (3--3) = (3+3)  6

 and the y distance is (5--5) = (5+5) =  10

 We can use the Pythagorean theorem to calculate the hypotenuse, which is the distance from E to D

a^2 + b^2 = c^2

6^2 + 10^2 = c^2

36+ 100 = c^2

136 = c^2

Take the square root of each side

sqrt(136) = sqrt(c^2)

We only take the positive square root since the distance must be positive.

sqrt(4)sqrt(34) = c

2sqrt(34) = c

c is approximately  11.66 units
