To find the percentage of a decimal, it is simple. Locate the decimal point (It is a period.) Move the decimal point to the right two place values, and put a percentage sign behind it. IN this case:
5.35 = 535%
535% is your answer
hope this helps
Using a t-distribution calculator and finding the p-value, the correct option regarding the conclusion is given by:
a) the p-value is 0.02. We reject h0 at the 5% significance level because the p-value 0.02 is less than 0.05.
<h3>What is the relation between the p-value and the conclusion?</h3>
It also involves the significance level, as follows.
- If the p-value is less than the significance level, we reject the null hypothesis
.
- If it is more, we do not reject.
In this problem, a t-distribution calculator for a right-tailed with <em>t = 2.15 and 25 - 1 = 24 df</em> is used to find a p-value of 0.02.
It is less than 0.05, hence option a is correct.

Given that
z = 3 cis(30°)
z = 3 (cos(30°) + i sin(30°))
by DeMoivre's theorem it follows that
z³ = 3³ (cos(3×30°) + i sin(3×30°))
z³ = 27 (cos(90°) + i sin(90°))
z³ = 27 (0 + i)
z³ = <u>0</u> + <u>27</u> i
-81 is the answer to the question.
