Answer:
about 4.52
Step-by-step explanation:
Since pi times radius squared is the formula for area, you would first divide 64 by 3.14 to get about 20.4. Then since you square the radius, you would do the opposite and find the square root which is about 4.52.
The mean absolute deviation is 10.52.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It is a measure of variation of a data set.
MAD =1/n ∑ l x - m(x) l
Where:
n = total numbers in the data set
x = number
m(x) - median
The first step is to determine the mean of the data set: (42 + 31 + 1 + 1 + 2 4+ 5 + 6 + 7 + 3) / 10 = 10.2
Find the absolute value of the difference between the number and the mean. Add the result | (42 - 10.2) + (31 - 10.2) + (1 _ 10.2) + (1 - 10.2) + (2 - 10.2) + (4 - 10.2) + (5 - 10.2) + (6 - 10.2) + (7 - 10.2) + (3 - 10.2) = 105.2
Divide the sum by the total number in the dataset = 105.2 / 10 = 10.52

Answer:
√7 ≈ 2.646
Step-by-step explanation:
The triangle apparently has two sides of length 4 and a third side of length 6. The altitude of the triangle will divide the long side in half, making that half one leg of the right triangle with hypotenuse 4.
The altitude of interest is then the length of the other leg:
√(4² -3²) = √7 ≈ 2.646
1+2+3=6 and 1x2x3=6 so your answer is 1,2 and 3.
72 I am guessing because you divide by 3
