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.

Answers

Given:
Profit = 372.60 + 17.2(advertising dollars)
Advertising dollars = 1,020
profit = 17,500

17,500 + residual value = 372.60 + 17.2(1,020)
17,500 + residual value = 372.60 + 17,544
17,500 + residual value = 17,916.60
residual value = 17,916.60 - 17,500
residual value = 416.60

residual value is 416.60 or 417 rounded off to the nearest integer

Which equations illustrate the associative property of addition? Choose exactly two answers that are correct. A. (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]
B. –3 • (5 + 8.5) = –3 • 5 + (–3) • 8.5
C. + 1.8 = 1.8 +
D. –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)

Answers

Solutions

Associative Property is a rule that refers to grouping. The rule is "a + (b + c) = (a + b) + c".

The correct answers are (A) and (D)

(A) = (11 + 2.2) + (–5) = 11 + [2.2 + (–5)]

(D) = –7 + [4 + (–2.1 • 6)] = (–7 + 4) + (–2.1 • 6)

If f(x)= -x+7 what is f(15)?

Answers

x = 15

Substitute that to equation

-(15) + 7

Answer:
f(x) = -8

F(x)=-x+7, and by saying “f(15)”, your saying x=15, since f(x) turns into f(15). So just replace all x’s with 15.

F(15)=-15+7
F(15)=-8

So -8 is the answer:)
