Step-by-step explanation:

(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain

For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:

x: number of hours studied.

y: test scores.

The linear relationship would be of the form:

y = mx + b

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?

y = 8x + 40

For three hours of study we have that the note would be approximate:

y = 8 * (3) + 40

y = 64

(c) What does the number 40 in Part (b) mean in the context of the situation?

The number 40 means that if you do not devote any study time, then you expect the test score to be 40.

I honestly need help on this...I tried to work it out but I just don’t know where to start...
Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

1) The sum of angles on a straight line is 180 degrees. Therefore

75 + a + 70 = 180

145 + a = 180

a = 180 - 145 = 35 degrees

2) Sum of the angles in a triangle is 180 degrees. Therefore,

a + b + 95 = 180

35 + b + 95 = 180

130 + b = 180

b = 180 - 130 = 50 degrees

3) c + 95 = 180 degrees (sum of angles on a straight line).

c = 180 - 95 = 85 degrees

4) 70 + c + d = 180 degrees

70 + 85 + d = 180

155 + d = 180

d = 180 - 155 = 25 degrees

5) e = 75 degrees

6) f + e + 75 = 180 degrees

f + 75 + 75 = 180

f + 150 = 180

f = 180 - 150 = 30 degrees
