Answer:
D. 30
Step-by-step explanation:
-5(-8)(3)(-1) /(-4)
Lets simplify the numerator first
-5*-8 = 40
40 *3 = 120
120*-1 = -120
Replace -5(-8)(3)(-1) with -120
-120/-4
A negative divided by a negative is a positive

Step-by-step explanation:
- Area of shaded region = 2571.66 in²
Radius of smaller circle = 25 in
Radius of larger circle = 25 + 13 = 38 in
Area of ring : Area of larger circle - Area of smaller circle
Answer:
Data Set B
Step-by-step explanation:
Mean Absolute Deviation(MAD) can be defined as the distance between one data point (value) to the Mean in a give Data set
It can also be defined as the deviation of the mean from the data points or values given in a data set.
From the above question, we are told that:
The mean of data set A ls 43.5 and the MAD is 3.7.
The mean of data set B is 12.8 and the MAD is 4.1.
Comparing the two Data set, the Mean Absolute Deviation of Data set A is smaller than that of Data set B.
Hence, Data set B shows a greater degree of variability because the distance between a data point(value) and the mean is 4.1. This also means that the data points in Set B are more spread out compared to the data points in Set A.
