Answer:
A = 1100cm^2
Step by step Explanation:
given the dimensions of width and length of the picture are x+20 by 2x-10 and the frame is a constant 5 cm wider from the edge of the picture to the frame, than the area of the frame is defined as (x+30)(2x)-(x+20)(2x-10) = 30x+200.
If the width is equal to the length which I assume is true if the width is constant.
than x+30=2x, which means x = 30.
if this is true than 30(30)+200 = 1100cm^2

Answer:
8
Step-by-step explanation:
Recall the formula for the population mean of a data set:

We already know that μ is 6 and the sum is 48. Substitute:

Divide both sides by 48:

Reciprocal of both sides:

Thus, there are 8 scores in the population size.
And we're done!
