Answer:

\frac{7}{25}

sinx = \frac{opposite}{hypotenuse}

The hypotenuse = 25 since 7, 24, 25 ← Pythagorean triple

Hence

sinx = \frac{7}{25}

What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth?
Romashka [77]
To find the mean of a set, add up all of the data points and divide by the number of data points.
For the first set:
(14+18+21+15+17) ÷ 5 = 85 ÷ 5 = 17
For the second set:
(15+17+22+20+16) ÷ 5 = 90 ÷ 5 = 18

To find the MAD (mean absolute deviation) of a set, find the mean of the distances of each data point from the mean.
For the first set:
(3+1+4+2+0) ÷ 5 = 10 ÷ 5 = 2
For the second set:
(3+1+4+2+2) ÷ 5 = 12 ÷ 5 = 2.4

To find the means-to-MAD ratio of a set, divide its mean by its MAD.
For the first set:
17 ÷ 2 = 8.5
For the second set:
18 ÷ 2.4 = 7.5
