Answer:
Area of a trapezoid flat land = 1400mi ^2
Step-by-step explanation:
Area of a trapezoid is easy to remember
= shaped front face = house with sloped sides flat roof.
bases actually are the parellel lines, which we add.
290 mi + 410 = 700 (non slope)
Then we multiply the height of the slope = 20 x 700 (with the non slope squarer shape) 20 x 700 = 1400mi ^2

Answer:
The answer is not complete. But you can use a spreadsheet to construct a simulation model to estimate the average profit per unit of a set of data.
Step-by-step explanation:
To calculate the Expected value of profit, we use:
Selling price - Expected value of different costs
Selling price is Total Cost * Probability
Confidence Interval
A Confidence Interval is a range of values that someone can be sure the true value lies in.
To calculate the confidence interval, we use the formula x ± z * S/√n
Where S is the standard deviation
n is the number of observations
x is the mean
z is the chosen z value
X/3 - 38 = 42
x/3 = 80
x = 240
