Answer:

w = 36 inches

Step-by-step explanation:

Since the two rectangles are similar, the ratios of their height is equal to the ratio of their widths.

Therefore, you can make an equation such that:

\frac{width_1}{width_2} = \frac{height_1}{height_2}

width 1 = 9 inches

width 2 = w inches

height 1 = 20 inches

height 2 = 80 inches

Plug into the ratio equation:

\frac{9}{w} =\frac{20}{80}

\frac{9}{w}=\frac{20 * 1}{20 * 4}= \frac{1}{4}

\frac{9}{w} =\frac{1}{4}

9 * 4 = 1 * w

w = 9 * 4 = 36 inches

Each year farmer records the number of pumpkins he sold for 5 weeks. The mean is 782 and the mean absolute deviation is 52. List
BARSIC [14]

Answer:

When we have a mean M and a standard deviation S, the values that are within the mean absolute deviation are all the values in the interval:

[M -S, M + S]

In this case, we have:

M = 782

S = 52

Then the interval is:

[782 - 52, 782 + 52]

[730, 834]

Then any number between 730 and 834 are possible answers to this question, for example, we can choose:

789 and 801
