Answer:
pretty sure its d
Step-by-step explanation:
the quadrant one function has asymptotes at y=0 and x=0 so x and y have to stay positive
the quadrant three function has asymptotes at y=0 and x=0 so x and y have to stay negative

<h2>
Answer with explanation:-</h2>
Let be the population mean.
By considering the given information , we have
, since the alternative hypothesis is right tailed , so the test is right tail test.
Given : Sample size : n=64, which is a large sample (n>30) so we use z-test.
Sample mean :
Then, Standard deviation :
Test statistic for population mean :-
i.e.
P-value =
Since the p-value is less than the significance level , so we reject the null hypothesis that mean we can accept the alternative hypothesis.
Thus , we conclude that the true mean concentration can exceeds 22 blops .

third answer
When a negative number is in a pair of | |, it turns into a positive. Positive numbers stay the same.
