Answer:
the connection is at 4 on x axis and 5 on y axis, so the solutions are x=4; y=5
You proofread 2 pages per minute so you divide 96 by 2 to get 48 minutes which is the answer
Answer:
Now we can find the p value using the alternative hypothesis with this probability:
Since the p value is large enough, we have evidence to conclude that the true proportion for this case is NOT significanctly higher than 0.75 since we FAIL to reject the null hypothesis at any significance level lower than 30%
Step-by-step explanation:
Information provided
n=100 represent the random sample selected
estimated proportion of students that are satisfied
is the value that we want to test
z would represent the statistic
represent the p value
System of hypothesis
We want to verify if more than 75 percent of his customers are very satisfied with the service they receive, then the system of hypothesis is.:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
Now we can find the p value using the alternative hypothesis with this probability:
Since the p value is large enough we have evidence to conclude that the true proportion for this case is NOT significanctly higher than 0.75 since we FAIL to reject the null hypothesis at any significance level lower than 30%
Answer:
A) 180.08 feet
Step-by-step explanation:
The diagram depicting the situation is shown in the attachment.
From the diagram the height is f ft.
The side we are trying to find is opposite to the given angle which is 
We use the tangent ratio to obtain;

We solve for f to get:
