Given are the data for two variables, x and y.

xi 6 11 15 18 20
yi 6 8 12 20 30
Enter negative values as negative numbers.

Compute b 1 and b 0 (to 4 decimals).

b 1
b 0

Complete the estimated regression equation (to 2 decimals).
= + x

the answer is a

step-by-step explanation:

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
