Answer:

The answer is D

Step-by-step explanation:

The graph starts at 40 so you know that Gary has 40 stamps originally. At 4 weeks you can clearly see he now has 60 stamps, so he has earned 20 in 4 weeks. To find out how many stamps he earned per week you do 20/4 which equals 5. So he has 40 to start and gains 5 stamps each week after.

The legs of a 45 45 90 triangle are congruent so if one leg is x we can write (using the Pythagorean Theorem):

x² + x² = 18²

2x² = 324

x² = 162

x = 9√2

Arada [10]

Mean absolute deviation is a statistical measure of dispersion. Whisker box-plot is a graphical method of quartile based divided data

Step-by-step explanation:

Mean Absolute Deviation is a statistical measure of dispersion or variability  in data. It denotes average level of deviation of observations from the central mean.

It is calculated using following formula : ( Σ | X - X' | ) ÷ N ; where X = individual observations, X' = mean, N = no. of observations
