Find the mean:
6 + 6 +10 + 8 + 10 +8 = 48
48 / 6 = 8
The mean is 8.
Now for each number, subtract the mean and square the result:
6 -8 = -2, -2^2 = 4
6 – 8 = -2, -2^2 = 4
10 – 8 = 2, 2^2 = 4
8 – 8 = 0, 0^2 = 0
10 – 8 = 2, 2^2 = 4
8 – 8 = 0, 0^2 = 0
Now find the mean of those results:
4 + 4 +4 +0 +4 + 0 = 16
16 / 6 = 2.6666
Now find the square root:
SQRT(2.666) = 1.63
The answer is A.
I'm not sure what you're asking here but if something's a parallelogram, all of the sides across from each other are parallel
Answer:
1872 in
Step-by-step explanation:
156 ft x 1ft = 156ft cause if you multiply 1 with any number its what ever number you multiplied 1 with.
Answer:
N = 18
Step-by-step explanation:
The triangles are similar, thus the ratios of corresponding sides are equal, that is
= ( cross- multiply )
5N = 90 ( divide both sides by 5 )
N = 18
