Answer:
16
Step-by-step explanation:
x^(-y) = 1/x^y
Answer:
L = 12
W = 8
Step-by-step explanation:
Area = L*W
L = W + 4
W = W
Area = 96
W ( W + 4) = 96
w^2 + 4W = 96
w^2 + 4w - 96 = 0
(w - 8)(w + 12) = 0
Only w - 8 = 0 will work
w - 8 = 0 Add 8 to both sides
w = 8
w + 12 = 0 will not work because you have to subtract 12 from both sides to get the value for w.
w = - 12 which has no meaning for garden plots.
So the width = 8 and the length = w + 4 = 8 + 4 = 12
Answer: Estimated the standard deviation α = 5.35
Step-by-step explanation:
According to Empirical rule, the largest value is approximately:
ц + 3α
And the smallest value is approximately:
ц + 3α
Based on the given figures in the question, we can say
ц + 3α = 140.6
ц - 3α = 108.5
Now subtracting these two; we have
ц + 3α - ( ц - 3α ) = 140.6 - 108.5
ц + 3α - ц + 3α = 32.1
6α = 32.1
α = 32.1 / 6
α = 5.35
Estimated the standard deviation α = 5.35
