If initially the car was valued at 44,000$, and after 9 years it's value dropped to 15,000$, we can say that the car's value dropped in 29,000$. If we suppose that the drop is the same every year, we can say that it was of 3,222,2$ by each year.

This amount of money is the 7,3% of the initial value of the car (I multiplied 3,222,2 x 100 : 44,000).

a) The annual rate of change was of 7,3%.

b) There are 14 years between 1993 and 2007. If we multiply 7,3% by 14, we get that the car lost 102,2% of it's initial value.

A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greate

suter [353]

Answer:

x ≥ 36 miles per hour

Step-by-step explanation:

The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.

Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:

x ≥ 110 miles per hour - 74 miles per hour

x ≥ 36 miles per hour

This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to

gtnhenbr [62]

Answer:

The variables are likely to present a positive linear relationship

Step-by-step explanation:

Land is commonly priced as a linear function of area, be it in km², miles² or acres. That is, it is usual to assign a monetary value to a unit of area. Therefore, the price of land (P) as a function of its area (A), in acres, can be given by:

$P(A) = kA$

Where 'k' is a positive constant rate as price increases when area increases. Therefore, the two given variables are likely to present a positive linear relationship.
