Answer:
The answer is x=-1
Answer: Angle 2 = 127 degrees, Angle7 = 127 degrees, Angle 8 = 53 degrees
Step-by-step explanation:
Angle 2 = 127 degrees because it is supplementary to 53 degrees.
Angle 7 = 127 degrees because it is alternate exterior to angle 2.
Angle 8= 53 degrees because it is supplementary to angle 7.

Answer: c. 39.14 to 42.36
Step-by-step explanation:
We want to determine a 95% confidence interval for the average hourly wage (in $) of all information system managers
Number of sample, n = 75
Mean, u = $40.75
Standard deviation, s = $7.00
For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
40.75 +/- 1.96 × 7/√75
= 40.75 ± 1.96 × 0.82
= 40.75 + 1.6072
The lower end of the confidence interval is 40.75 - 1.6072 =39.14
The upper end of the confidence interval is 40.75 + 1.6072 =42.36
This is easy it's
-33x-82
