Step-by-step explanation:
The answer is 26 or 24 because I didn't understand what you have written after +
First, substitute -2 into each equation where there is an <span>x:
</span>(-2)2 -8<span>
</span>(-2) +6
Then multiply the -2 and the 2 in the first equation and add -2 and 6 in the second:
-4 -8
4
Lastly, subtract -4 and 8:
-12
4
Now you have you answers -12 and 4!

Answer:
D)We are 95% confident that the proportion of adults (ages 17‐26) who attended college during the past 4 years and say that alcohol and drug use at their school is a big problem is between 53% and 59%.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true proportion for the population of adults who attended college who say that alcohol is a big problem is between 0.53 and 0.59. This means that the answer is given by option D.
