Regression analysis was applied between sales data (in $1,000s) and advertising data (in $100s) and the following information was obtained: y=12+1.8x, n=17, ssr=225, sse=75, and sb=0.2683. based on the information provided, if advertising is $3,000, then the point estimate for sales (in dollars) is

select one:
a. $66,000
b. $5,412
c. $66
d. $17,400
e. none of the above answers is correct

A. $66,000

Step-by-step explanation:

The relationship between sales data (in $1,000s) and advertising data (in $100s) is:

If  if advertising is $3,000, then x =$30, and the point estimate for sales (in thousands of dollars) is:

Converting it to dollars, the point estimate for sales is:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
