Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.
Answer:
Step-by-step explanation:
The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108
First we need to write the null and alternate hypothesis for this case.
Let x be the average number of text message sent. Then
Null hypothesis: x = 100
Alternate hypothesis: x > 100
The p value is 0.0853
If p value > significance level, then the null hypothesis is not rejected. If p value < significance level, then the null hypothesis is rejected.
If significance level is 10%(0.10), the p value will be less than 0.10 and we reject the null hypothesis and CAN conclude that:
The mean number of text messages sent yesterday was greater than 100.
If significance level is 5%(0.05), the p value will be greater than 0.05 and we cannot reject the null hypothesis and CANNOT conclude that:
The mean number of text messages sent yesterday was greater than 100.
