The average cost of a compact car at a certain dealership over the last ten years has ranged from $14,000 to $18,500. Suppose yo
mezya [45]

Answer:

Part (A): The scale of y: 1 interval being equal to 500 units and from 14,000 to 18,500.

Part (B): The good interval to use for the y-axis should be 1 to 10.

Step-by-step explanation:

Consider the provided information.

As we know the X axis represents the independent variable, since years are the independent variable. So, X axis represents the years.

Y axis represents the dependent variable, since average cost is dependent variable. So, Y axis represents the average cost.

Part (A) what is a good scale to use for the y-axis?

It is given that range is from $14,000 to $18,500.

So, 1 interval being equal to 500 units, so that it will suitable for 18,500.

The scale of y should be 14,000 to 18,500 as 14,000 is the starting average cost and 18,500 is the last average cost.

Part (b) what is a good interval to use for the y-axis?

The scale for x should be 1 year. As It should start from 1 to 10.

The good interval to use for the y-axis should be 1 to 10.

The required scale is shown in figure,

PLZ ANSWER THIS CORRECTLY FOR 100 POINTS AND BRANLIEST :DD

Actually Welcome to the Concept of the Angles,.

Since,the AE is a angle bisector, hence, BAE = EAC simply.

hence we equate them..

===> x+ 30 = 3x - 10

==> 3x - x = 30 + 10

==> 2x = 40

==> x = 20°

hence the major angle EAC = 3(20)-10 = 60-10 = 50°

hence, angle EAC = 50°
