Asap! brainliest!

data regarding fuel efficiency of an 18-wheel truck were collected. the graph shows the correlation between the average speed above 40 miles per hour (in miles per hour) and the money spent on gas (in dollars):

image of a scatter plot with average speed on the x axis and money spent on fuel on the y axis with points 1 comma 2, 3 comma 2 and one half, 5 comma 5, 7 comma 7, 9 comma 10, 11 comma 15, and 12 comma 17

estimate the average rate of change from x = 5 to x = 9.

4
−4
0.8
1.25

Step-by-step explanation:

From the problem, x-axis is Average Speed, and y-axis is Money Spent.

When we talk about the rate of change, we refer to the ratio of each variable change, how much change the Average Speed with respect to Money Spend, this is geometrically referring to a slope, which is the ratio of change of a linear relation between two variables.

So, the points to calculate the ratio are (5;5) and (9;10), because the problem is asking from x = 5 to x = 9:

This means that the ratio is 1.25 units of money spent by each unit of average speed.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000
