Answer:
395, 17.212
(360.576,429.424)
Step-by-step explanation:
Given that a procedure yields a binomial distribution with n trials and the probability of success for one trial is p.
Here
Since np and nq are greater than 5 by rule of thumb we can approximate binomial to normal.
Mean = np = 395
Variance = npq =
Std dev = 17.212
Thus X no of successes is N(395, 17.212)
THe the minimum usual value mu minus 2 sigma and the maximum usual value mu plus 2 sigma would be
Using the given information, the area of figure B is 315 ft²
<h3>Calculating Area </h3>From the question, we are to calculate the area of figure B
In the given diagram, figure B is made up of a triangle and a square
∴ Area of figure B = Area of triangle + Area of square
Area of triangle =
Where b is the base
and h is the height
Area of square =
Where is the length of a side
In the diagram,
∴ Area of figure B =
∴ Area of figure B = (15×6) + 225
∴ Area of figure B = 90 + 225
∴ Area of figure B = 315 ft²
Hence, the area of figure B is 315 ft²
