Answer: <em>In the upper triangle x = 33° and in the lower triangle x = 128°</em>
Step-by-step explanation:
<em><u>Upper triangle:
</u></em>
<em>x = (180° - 114°) ÷ 2 = 33°</em>
<em><u>Lower triangle:</u></em>
<em>x = 180° - 26° × 2 = 128°</em>
Answer: The coordinates of M would be (3,2).

Answer:
Null hypothesis:
Alternative hypothesis:

And the best answer for this case is:
C. p-value
Step-by-step explanation:
Data given and notation
n represent the random sample taken
estimated proportion of interest
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the true proportion i 0.72 or no.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statistic, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value
.
For this case the only probability that can be calculated from the statistic calculated is the p value given by:

And the best answer for this case is:
C. p-value
