Some students were surveyed about how much time they spent playing video games last week and their overal test average.
sashaice [31]
A) The attachment shows the equation of the best-fit line. It is approximately
.. test average = 89.7 -2.93*(hours playing games)

b) The slope indicates the expected drop in test score for each hour spent playing games

c) The y-intercept is the expected test score if no hours are spent playing games.

d) The correlation coefficient is -0.92, a significant negative correlation. One might expect that hours spent playing games indicates a lack of interest in school subjects or studying, hence a likelihood that test scores will be lower.

e) The equation predicts a test score of about 75 for someone who spends 5 hours a week playing video games.

A. 40x^2 + 240x + 200
Shape: Rectangle
Formula: A = LW
A = (10x + 10)(4x + 20)
= (10x)(4x) + (10x)(20) + (10)(4x) + (10)(20)
= 40x^2 + 200x + 40x + 200
= 40x^2 + 240x + 200

x = 35
Plug-In:
10x + 10
10(35) + 10
350 + 10
360 = Length
————————————-
