Which of the statements below is true for the following set of numbers? 20,15,50,85,75,60

The range is 70 and the midrange is 35.
The range is 70 and the midrange is 50.
The range is 85 and the midrange is 55.
The range and the midrange are equal.

The range is calculated by subtracting the smallest number from the highest number of a sequence:

65 - 15 = 50

The midrange is calculated by adding the smallest and the highest number of a sequence and than dividing the result by 2:

65 + 15 = 80

80 / 2 = 40

The range is 50 and the midrange is 40 (c).

Hope it helped,

Happy homework/ study/ exam

Step-by-step explanation:

I think it's B, the range is 70 in the mid-range is 50

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
