Liz's math test included a survey question asking how many hours students spent studying for the test. The scatterplot and regre
ssion line below show the relationship between how many hours students spent studying and their score on the test.
The fitted line has a slope of 15.
What is the best interpretation of this slope?
A
The model predicts that students who scored 0 studied for an average of 15 hours.
(Choice B)
B
The model predicts that students who didn't study at all will have an average score of 15 points.
(Choice C)
C
The model predicts that the score will increase 15 points for each additional hour of study time.
(Choice D)
D
The model predicts that the study time will increase 15 hours for each additional point scored.

Answer:
15.5 feet
Step-by-step explanation:
Given:
Patty is building a rope ladder tree house she needs two 4 foot pieces of rope for the sides of the ladder.
She needs 6 pieces of rope each 15 inches long for the steps.
Question asked:
How many feet of rope does patty need to make the ladder ?
Solution:
She needs for the sides of the ladder = Two 4 foot pieces of rope
= 2 4 feet = 8 feet
She needs for the steps of the ladder = 6 pieces of 15 inches long rope
= 6 15 inches = 90 inches
Convert 90 inches into feet:-
12 inches = 1 feet
1 inches =
90 inches =
Patty needs total rope = 8 feet + 7.5 feet
= 15.5 feet
Thus, Patty needs 15.5 feet of rope to make the ladder.
