Answer:
D. A value of 0.9 is more than 2 standard deviations from the mean
Step-by-step explanation:
In the figure attached, the distribution of data is shown.
From the picture we can see that:
- The data has a standard deviation of 0.15 (= 0.5 - 0.35 = 0.65 - 0.5)
- The mean of the data is 0.5
- A value of 0.7 is more than 1 standard deviation of the mean.
- A value of 0.9 is more than 2 standard deviations from the mean (0.8 is 2 standard deviations from the mean)
<span>You take the probability of success (and the revenue generated by it) and the probability of failure (and the cost associated with trying it) and get an expected value:
aP(a) + bP(b)
I hope my answer has come to your help. God bless and have a nice day ahead!

using the ratio, the length of the sides are:
25x + 14x + 12x = 170
51x = 170
x = 170 / 51
x = 3 1/3
The lengths of the sides are: 25 * 3 1/3 = 83 1/3 feet
14 x 3 1/3 = 46 2/3 feet
12 x 3 1/3 = 40 feet
Using Heron's formula
the semi perimeter (S) = 170/2 = 85 ft.
The area of the triangle = SQRT(S*(S-83 1/3) * (S - 46 2/3) * (S-40))
= SQRT (85 * (85-83 1/3) * (85 - 46 2/3) * (85-40)
= SQRT (85 * 1 2/3 * 38 1/3 * 45)
= SQRT(244374)
= 494.34 square feet ( round answer as needed).
