Find the value of x. Then find the angle measures of the polygon.
2 answers:
Answer:
x° = 125°
(x+10)° = 135°
Step-by-step explanation:
<u>Given:</u>
Sum of measures of angle = 720°
<u>Solution:</u>
We know that:
Sum of measures of angle = 720°
120 + 100 + 120 + x + 10 + 120 + x = 720
x + x + 120 + 100 + 120 + 10 + 120 = 720
2x + 470 = 720
2x = 720 - 470
2x = 250
Divide both sides by 2
x = 250/2
x = 125
Now,
<u>Angles measures</u>
x° = 125°
(x+10)° = (125+10)° = 135°

Answer:
The appropriate null hypothesis is
The appropriate alternative hypothesis is
Step-by-step explanation:
Exactly a year prior to this poll, in June of 2004, it was estimated that roughly 1 out of every 4 U.S. adults believed (at that time) that the war in Iraq was the most important problem facing the country.
At the null hypothesis, we test if the proportion is still the same, that is, of . So
We would like to test whether the 2005 poll provides significant evidence that the proportion of U.S. adults who believe that the war in Iraq is the most important problem facing the U.S. has decreased since the prior poll.
Decreased, so at the alternative hypothesis, it is tested if the proportion is less than 0.25, that is:
