We can use the calculator to evaluate whether the domain given is possible or valid. In this case, A includes number equal to zero. log zero is invalid. B includes negative numbers. The values are still invalid. The numbers greater than zero are valid. Answer then is C
Answer:
Option C
23.08% markup on selling price.
Step-by-step explanation:
Given in the question,
markup percentage on cost price = 30%
To find,
markup percentage on selling price
Markup is the ratio between the cost of a good or service and its selling price.
Let suppose that cost price percentage = 100%
As we know that,
<h3>cost% + markup% = selling%</h3><h3>100% + 30% = 130%</h3>
So percent markup selling price = 30 / 130 x 100
= 23.0769
Hence, 30% markup on cost price = 23.0769% markup on selling price.
$120 per each student x 495 students = $59,400

Answer: -3.0593
Step-by-step explanation:
The test statistic for the difference between two population mean (when population standard deviations 
are known ) is given by :-
where ,
= Sample sizes taken from two populations 1 and 2.
= Difference between two Sample mean.
= Standard deviations of populations 1 and 2.
As per given , we have
We assume that the data follows a normal distribution.
Then, the test statistic will be :-
Hence, the test statistic= -3.0593
