The sum of all exterior angles add up to 360º. To find the missing 3rd exterior angle subtract the sum of the first two exterior angles from the total sum of all exterior angles.
360º - 220º = 140º
The measure of the third exterior angle is 140º.
Answer:
The p-value of the test is 0.2.
Step-by-step explanation:
Using the alternative hypothesis that µ ≠ 531, Amy found a t-test statistic of 1.311.
Alternative hypothesis means that e have a two-tailed hypothesis test.
Sample 30 citizens. Amy found a t-test statistic of 1.311.What is the p-value of the test statistic?
Thus, we have a two-tailed test with 30 - 1 = 29 degrees of freedom and t = 1.311. So, using a t-distribution calculator, the p-value of the test is 0.2.

Answer:
1
Step-by-step explanation:
= -2 + 7 + (-4)
=5+(-4). (because positive and negative form negative)
=5-4
=1
