Ryan surveyed people about the total money they spend with respect to the number of hours they spend at a shopping center. he recorded the results of the survey in the scatter plot below. select all the correct answer's

a. the scatter plot contains more than 4 outliers.

b. the point (8,80) is an outlier, because it represents the customer who spent the most time shopping.

c. the point (2,60) is an outlier, because it is far away from the rest of the points.

d. there is an outlier at (4.5,15).

e. there is an outlier at (5.5,45).

f. the point (7.5,85) is an outlier, because it represents the customer who spent the most money.

-There is an outlier at (4.5,15).

-The point (2,60) is an outlier, because it is far away from the rest of the      points.

Step-by-step explanation:

An outlier is a data point that is far away from the rest of the data. An outlier does not necessarily represent the extremes in a set of data, as long as it is close to the other points. So, based on the scatter plot, there are two outliers at (2,60) and (4.5,15).

The following statements are true.

There is an outlier at (4.5,15).

The point (2,60) is an outlier because it is far away from the rest of the points.

i just took the test, the correct answer is .. 31.5 in.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
