Answer:

h=24

Step-by-step explanation:

V= 1/3πbh

V=1/3π4h

32π=1/3π4h

b=base/radius

v=volume

h=height

you want to times 3 to both sides because of reciprocal of 1/3 to get

96π=π4h

divide π from both sides

96=4h

divide 4 from both sides

24=h

GalinKa [24]

Answer:

Q1

slope=0.16

intercept=30.2

Q2

78.2

Q3

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%.
