Answer: option C. 9,555.

Justification:

1) The summation is:

6
∑  7(4)^ (i - 1)
i=1

2) Substitute with the values of i from 1 to 6 (note that 7 is a common factor of all the terms) =>

7 { 4^(1-1) + 4^(2-1) + 4^(3-1) + 4^(4-1) + 4^(5-1) + 4^(6-1) } =

= 7 { 4^0 + 4^1 + 4^2 + 4^3 + 4^4 + 4^5 } = 7 { 1 + 4 + 16 + 64 + 256 + 1024} =

7{1365} = 9,555.

Answer: 9,555

Art [367]

Answer:

d. The slope of the relationship between firstfloorsquarefootage and price is moresteep for homes near the beach than elsewhere in Tampa.

Step-by-step explanation:

In this regression model, we have a positive slope. This positive slope is indicative of an increase. So to interpret this slope, we would say that the slope of the relationship that exists between the two variables (price and firstfloorsquarefootage) is steeper for the homes that are closer to the beach compared to the ones that are elsewhere. Therefore option D is our answer.
