Answer:
Hope this helps :)
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 approximately:
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.

Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 
. Therefore, an equiangular triangle will have each of its angles equal to 
. We can then set up the following equation:
.
Answer:
20%
Step-by-step explanation:
- Start by changing the fraction to a decimal by diving the numerator by the denominator ( 1 divided by 5 ). That equals 0.2 .
- Change the decimal to a percent by multiplying it by 100% , or moving the decimal two places. That gives you 20% .
