An airplane company flies 45 airplanes daily. The CEO collects the following passenger counts for a random sample of airplanes
from the fleet, as shown below.
119, 138, 157, 85, 157, 119, 138, 119, 157, 85

Assuming that the sample is representative of the entire fleet of airplanes, what would be the mean daily passenger count per
plane?

A. 124.75
В. 135.9
C. 127.4
D. 128.5


Answers

Answer 1
Your answer would be C

Step by step:
Start with 10 flights it gives you
Assuming this data is rhe same for each 10 flights you should divide 45 by 10 to get an average of 4.5. (the amount of sets of 10 planes) You then use this number as a constant multiplying it by the number of planes with the same amount of passengers.(in this case 3 flights with 119 passengers) So that would look like this: 4.5 x 3=13.5 (the number of total flights with 119 passengers) Continue to do this with each number set, add them all up, and divide them by the total number of planes, 45.

Use the graph that shows the number of laps completed over time. Find the slope of the line.​

Answers

By using the given graph, we will see that the slope of the linear equation is:

a = 0.5 laps per minute.

How to find the slope of the line?

For a linear equation:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:

a = (y₂ - y₁)/(x₂ - x₁).

So we need to look at the graph and identify two points, we will use:

(10 min, 5) and (20 min, 10)

So the slope is:

a = (10 - 5)/(20 min - 10 min) = 0.5 laps per minute.
