18 + m/4 = 24
Subtract 18 from each side:
m/4 = 6
Multiply each side by 4 :
<em>m = 24 </em>
In elementary algebra, a trinomial is a polynomial consisting of three terms or monomials.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 25235
For the alternative hypothesis,
µ > 25235
This is a right tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 27524
µ = population mean = 25235
s = samples standard deviation = 6000
t = (27524 - 25235)/(6000/√100) = 3.815
We would determine the p value using the t test calculator. It becomes
p = 0.000119
Since alpha, 0.05 > than the p value, 0.000119, then we would reject the null hypothesis. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.
These two claims about markup and margin are <u>equivalent</u> because they discuss differently the same issue.
<h3>What are markup and margin?</h3>
A markup is a profit percent added to the cost price to determine the selling price. Thus, markup relates the percentage of profit to the cost price.
The profit margin relates the percentage of profit to the selling price.
<h3>Data and Calculations:</h3>
Selling price = 100%
Profit margin = 25%
Cost price = 75% (100% - 25%)
Markup = 33% (25%/75% x 100)
Thus, these two claims about markup and margin are <u>equivalent</u>.
