Answer:
x = 26°
Step-by-step explanation:
The measure of the secant- secant angle x is one- half the difference of the measures of the intercepted arcs , larger subtract smaller
x =
(66° - 14°) = 0.5 × 52° = 26°
Answer:

Step-by-step explanation:
You can use the work they gave you and continue from there:

First, simplify the numerator:

Finally, simplify the denominator:

Answer:
Step-by-step explanation:
From the given information;
The null hypothesis & alternative hypothesis:

The test statistics can be computed as:




The p-value = 2(Z > 2.11) since this is a two-tailed test
The p-value = 2( 1 - Z < 2.11)
The p-value = 2 (1 -0.9826)
The p-value = 2 (0.0174)
The p-value = 0.0348
Decision Rule: To reject the
if the p-value is less than 
Conclusion: We fail to reject
and conclude that the population mean = 2, thus the machine is properly adjusted.
