Answer:

And replacing we got:


Step-by-step explanation:
For this case we have the following info given:
represent the mean
represent the deviation
We select a sample size of n=100. This sample is >30 so then we can use the central limit theorem. And we want to find the distribution for the sample mean and we know that the distribution is given by:

And replacing we got:


Increase in cash = 325,000- 250,000 = 75,000
increase percentage = 75,000 / 250,000 × 100 = 30 % Increase
Area of the figure=area of the square - area of the rectangle 1 - area of the rectangle 2.
Area of the square=side x side=12 * 12 =144
Area of the rectangle 1=8 *5=40
Area of the rectangle 2=5 * (12-8)= 5 * 4=20
Area of the figure=144 - 40 -20=84
Answer : 84
The answer is 1/2.
I got this answer by multiplying all of them.
3^0 = 1
1/2 * 1 = 1/2
