:)

the scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on social media in a week

part a: what is the group of points labeled a called? what is the point labeled b called? give a possible reason for the presence of point b.

part b: describe the association between a student’s test scores and the number of hours spent on social media.

The group labeled A is a cluster. The point labeled B is an outlier, that could be because the student studied or already knew what was needed for the test.

Part B im not sure sorr

Step-by-step explanation:

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
