Answer:
65
Step-by-step explanation:
Exterior angle = Sum of 2 interior angles
x + 31 = x + x - 34
x + 31 = 2x - 34
x - 2x = - 34 - 31
- x = - 65
x = 65
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.
9) a = c/g
How: g = ca
g/c = ca/c
g/c = a
11) m = np/x
How: xm = np
xm/m = np/m
x = np/m
To the length of the third side, we need to know the angle between the given sides.
You did not provide this information.
You then need to use the law of cosines.
Answer:
(5412^2)-(7896) equals 29,281,848.
Step-by-step explanation:
5,412 squared, minus 7896, equals 29,281,848.
