Answer:
7
Step-by-step explanation:
It is 7:
31 - 7 = 24
15 - 7 = 8
8/24 = 1/3 = 33%
It is not 12:
31 - 12 = 19
15 - 12 = 3
3/19 = 15%
It is not 6:
31 - 6 = 25
15 - 6 = 9
9/25 = 36%
It is not 9:
31 - 9 = 22
15 - 9 = 7
7/22 = 31%
It is not 11:
31 - 11 = 20
15 - 11 = 4
4/20 = 20%
<u>I subtracted the option from 31 (the new total of marbles) and from 15 (the new total of blue marbles). Then, I divided the new total by the new total of the blue marbles. I converted the decimal into a percentage. If the percentage was not 33%, then it was not the answer.</u>
Answer:
3.14
Step-by-step explanation:
The statements that are true based on the scatter plot and the given equation of line of best-fit are:
- In general, the line of best fit indicates that, the cost of a car insurance policy for a 21-year-old should be on average of about $315 less than the cost of a car insurance policy for a 20-yr-old.
- Car insurance policy cost tends to decrease as age of driver increases.
Given that the correlation coefficient of -0.951, it suggests that the policy cost and ages of the men as shown in the scatter plot are strongly negatively correlated.
This means that, the lower the higher the age of the men, the lesser the cost of a car insurance policy.
The slope value in the equation, y = -315.67x + 8986.5, is -315.67, which is the average cost of a car insurance policy per year.
Therefore, the statements that are true based on the scatter plot and the given equation of line of best-fit are:
- In general, the line of best fit indicates that, the cost of a car insurance policy for a 21-year-old should be on average of about $315 less than the cost of a car insurance policy for a 20-yr-old.
- Car insurance policy cost tends to decrease as age of driver increases.

You would need to know how much the arcade game cost and how much the Ferris wheel cost then let x represent the amount of times she played the arcade game and let y represent how many times she rode the ferris wheel.
once given the x and y you could figure out how much money she spent all together.
