Answer:
b = 3 units
Step-by-step explanation:
Area of a parallelogram = base × height
Thus,
Area = 21 units²
base = b
height = 7
Plug in the value into the formula
Thus:
21 = b × 7
Divide both sides by 7
21/7 = b
3 = b
b = 3 units

Answer:
1. 8.576%
2. Yes
Step-by-step explanation:
1. Use the calculator
Enter: normalcdf(8, E99, 0, 5.9)
This is equal to .08756.
Convert this number into a percent = 8.756%
2.
First, calculate the residual
Residual = Observed - Predicted = 165 - 2.599(20) + 105.08 = 7.94
Use the calculator
Enter: normalcdf(7.94, E99, 0, 5.9)
This is equal to .0892.
Convert this number into a percent = 8.92%
This would be surprising, because the chance of this happening is very low.
