Answer:

64π or 201.0619298297

Step-by-step explanation:

Area of a circle: πr²

To find r, the radius of the circle, take the diameter (16) and halve it to get 8. You can now place 8 into the equation to get π8². Square 8 to get 64. You now now have π64, or 201.0619298297.

The sum of three numbers is 103. The second number is 5 less than the first. The third number is 4 times the first. What are the

madreJ [45]

Answer:

The numbers are 18, 13, and 72.

Step-by-step explanation:

Let the three numbers be represented by a, b, and c.

The sum of the three is 103. Thus, we can write that:

$a+b+c=103$

The second number is five less than the first. So:

$b=a-5$

And the third number is four times the first. So:

$c=4a$

Substitute:

$a+(a-5)+(4a)=103$

Solve for a. Combine like terms:

$6a-5=103$

Add five to both sides:

$6a=108$

And divide both sides by six. Therefore:

$a=18$

So, the first number is 18.

Since the second number is five less than the first, the second number is 13.

And since the third number is four times the first, the third number is 72.

GalinKa [24]

Answer:

slope=0.16

intercept=30.2

78.2

36%

Step-by-step explanation:

Question 1

We are given that

xbar=280

sx=30

ybar=75

sy=8

r=0.6

The regression line can be written as

y=a+bx

a=intercept

b=slope

where

$b=r\frac{sy}{sx}$

and

$a=ybar-bxbar$

b=0.6*(8/30)

b=0.16

a=75-0.16*280

a=30.2

Thus,

slope=0.16

intercept=30.2

Question 2

The regression line in the given scenario

y=30.2+0.16x

Julie pre exam total before the exam was 300.

y=30.2+0.16*300

y=30.2+48=78.2

So, the predicted final exam score of Julie is 78.2.

Question 3

R² denotes the variation in dependent variable y explained by the linear relationship of x and y.

R²=0.6²=0.36

Thus, the proportion of the variation in final exam scores that is explained by the linear relationship between pre-exam scores and final exam scores is 36%.
