Answer:
mean absolute deviation
Step-by-step explanation:
The mean absolute deviation of a data set is the average distance between each data point and the mean. It gives us an idea about the variability in a data set since it is a measure of dispersion
“y” is a part of a straight angle, so
131 + y = 180
y = 180 - 131
y = 49 [degrees].
5 is your answer
20/4 = 5 however,
2 x 2.5 = 5 (it doesn't work, cannot have decimals)
so 5 is your answer
hope this helps
The answer is D.
In the expression, the fraction must be larger than 1/4, yet smaller than 7/8.
It can't be A because 1/5 is smaller than 1/4. See below.
1/5 = 4/20
1/4 = 5/20
It also can't be B because 8/9 is larger than 7/8. See below.
8/9 = 64/72
7/8 = 63/72
Lastly, the answer cannot be C because 2/10 is smaller than 1/4.
1/4 = 5/20
2/10 = 4/20
Answer D works because:
10/20 = 2/4 > 1/4
10/20 = 80/160 < 140/160
