Inverse operations to the rescue!
So, you'd perform 22÷5 (product signals multiplication) to get your answer, 4.4. x=4.4
Area of a semi-circle = 1/2 x x r square.
area of larger semi circle
= 1/2 x x 10 square
= 50
area of smaller semi circle
= 1/2 x x 5 square
= 12.5
Total area = 50 + 12.5 = 196 cm square ( to 3 sf ) or 62.5
Answer:
If im not wrong the answer is 23,613.
Step-by-step explanation:
9,854+3,905=13,759+9,854=23,613.
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.
