Aregression analysis between sales y in $1000) and advertising (x in $100) resulted in the following squares line: y-82 +7x. this implies that if advertising is $900, then the predicted amount of sal dollars) is:
a. $6,382
b. $88,300
c. $145,000
d. $82,063
e. 6382000

The correct option is C) $145,000

Step-by-step explanation:

Consider the provided regression.

sales y in $1000 and advertising x in $100

We have given that they spent $900 in advertising.

That means substitute x=9 in above regression because x is in $100.

It is given that y in $1000.

That means the total sale is 145×$1000=$145000.

Hence, the correct option is C) $145,000

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
