Answer:
27°
Step-by-step explanation:
The inscribed angle is half the measure of the arc it intercepts.
∠M = 1/2 arc QR = 1/2(54°)
∠M = 27°
-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20
-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80
y=20
x=80
Hope this helps :)
Based on the responses, the significance level, and the p-value, we can conclude that the response proportions are not the same for the countries.
<h3>What can be concluded about the response proportions for these countries?</h3>
The null hypothesis is that the response proportions are the same. The alternate hypothesis is that the response proportions are not the same.
The sample size is large enough for a Chi-Square test to be used because the expected counts are all greater than 5.
Running a Chi-Square analysis shows that the P-value to be 0.000.
The P-Value is less than the significance level of 0.01 so the null hypothesis is rejected. This means that the alternate hypothesis of the response proportions not being the same is true.
