Answer:
OR 
Step-by-step explanation:
So first you find the difference between the new cost and the old cost:
450 - 370 = 80
So the increase was 80.
When you write it as a fraction you write the increase ( 80 ) over the starting cost ( 370 ).
Thus the answer becomes
But you can always reduce it to its lowest terms thus:

Let n = number of records.
Each record costs $7, so n records cost 7n.
She then spent $3, so the total spent is 3n + 3.
She spent a total of $24, so 3n + 3 must equal 24. That gives us the following equation.
7n + 3 = 24
Subtract 3 from both sides.
7n = 21
Divide both sides by 7.
n = 3
Answer: She bought 3 records.
The mean is 4.9 miles per day
Answer:
Increase (A)
Step-by-step explanation:
If the common ratio is greater than 1, that means the y-value increases as the x-value increases.
If the common ratio is 1, that means the y-value stays the same as the x-value increases.
If the common ratio is between 0 and 1, that means the y-value decreases and approaches 0 ad the x-value increases.
Because the common ratio is greater than 1, the answer is A, increases
Hi there!
Part A: Those groups of points that are circled and labeled A are called a correlation. In this case, the group of points represent negative correlation. The point that is labelled B is called an outlier, because it falls outside of the range of the other points. Point B may have been present like that, because while a person may spend a lot of time on social media, they might have understood the information very fast, or maybe they studied a bit on a different occasion.
Part B: Going back to part A, the graph represents a negative correlation. In this case, the more time spent on social media, the lower the test scores.
