Find the mean, median, mode, range, variance, and standard deviation of numbers 7 11 11 15 20 20 28

Hello!

The mean is 16.

The median is 15.

There is no mode. (11 and 20 both occur twice.)

The range is 21.

The standard deviation is 0.

Hope this was helpful. Correct me if i'm wrong. Have a great day!

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
