Algebra 1
the director of marketing at a large company wants to determine if the amount of money spent on internet marketing is a good predictor of company profit. she fits a least-squares regression line to 20 months of data and computes the following regression line:
profit = 372.6 + 17.2(advertising dollars)
what is the value of the residual for advertising dollars spent equal to $1,020 and profit equal to $17,500? round to the nearest integer.

$416.60

Step-by-step explanation:

In this question the expression is given in the form of a regression line given: profit = 372.6 + 17.2×(advertising dollars)

We have to find the residual value for the advertising dollars spent

= $1,020 and profit  = $17,500

We will calculate the profit for advertising dollars = $1,020

Profit = 372.6 + 17.2×(1020)

= 372.6 + 17544

= $17,916.6

But the profit is $17,500 so the difference in amount will be residual value

Residual value = 17,916.6 - 17,500 = $416.60

The value of residual is $416.60.

step-by-step explanation: yes

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
