Answer:
So, the population mean is 3.66.
Step-by-step explanation:
We will calculate the average value by summing all the values and dividing by the size of sample.
We have population contains six members, with values 1,1,2,3,5,10.
Therefore, n=6.
We use the formula to calculate the population mean:

So, the population mean is 3.66.
The greatest common factor<span>, or </span>GCF<span>, is the </span>greatest factor<span> that divides two numbers. To find the </span>GCF<span> of two numbers: List the prime </span>factors<span> of each number. Multiply those </span>factors<span> both numbers have in </span>common<span>.</span>
Answer:
Step-by-step explanation:
Each triangle is a right triangle, and all are congruent. So ...
90 -m∠CAB = (1/2)m∠CDA
90 -(4x +33) = (1/2)(12x +34)
57 -4x = 6x +17 . . . . . . . eliminate parentheses
40 = 10x . . . . . . . . . . . . .add 4x-17
4 = x
We also have ...
2m∠CAD = m∠BCD
2(3z +28) = 10z +28
6z +56 = 10z +28 . . . . . eliminate parentheses
28 = 4z . . . . . . . . . . . . . .subtract 6z+28
7 = z . . . . . . . . . . . . . . . . divide by 4
Since BC = CD ...
x = y = 4
The values of the three variables are ...
x = 4, y = 4, z = 7.
