<em>7=a-5. What does a equal?</em>

When solving an equation, it's always a great idea to make sure all variables are on the left side of the equation and the numbers are on the right.
Since in our equation, we have numbers on both sides, we need to move all numbers to one side:-
7=a-5
This is the same as
a-5=7
Now, add 5 on both sides:-
a=12
So we conclude that a=12.
<h3>Good luck with your studies.</h3>
Integrate both sides with respect to <em>x</em> :
On the right side, integrate by parts with
Then
Integrate both sides with respect to <em>x</em> by parts again, this time with
Then
Answer:
Step-by-step explanation:
Confidence coefficient is also the confidence level. A confidence coefficient of 0.95 is the same as a confidence level of 95%.
Confidence level is used to express how confident we are that the population mean lies within the calculated confidence interval. It expresses the possibility of getting the same result if tests are repeated. Since the study reports that college students work, on average, between 4.63 and 12.63 hours a week, with confidence coefficient .95, then the true statement is
G. We are 95% confident that the population mean time that college students work is between 4.63 and 12.63 hours a week.
