the data modeled by the box plots represent the battery life of two different brands of batteries that were tested.

(a) what is the median value of each data set?

(b) what is range for each data set?

(c) what is the interquartile range for each data set?

(A) x is 13 and y is 16

(B) x is 5 and y is 8

(C) x is 2.5 and y is 2

A steps:

brand X and Y, you would take you would look at the center quartile (2nd quartile).

B steps:

Brand X is 16-11=5

Brand Y is 18-10=8

C Steps:

 Brand X

   14.5             -          12         = 2.5

(3rd quartile)         (1st quartile)

Brand Y

    17                -            15        = 2

(3rd quartile)         (1st quartile)

Hope this helps you with your math and that its easy to understand!

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
