Answer:
one ceel is heterosexual the other is fruity
<u>Given</u>:
The given expression is 
We need to determine the value of x using either base - 10 or base - e logarithms.
<u>Value of x:</u>
Let us determine the value of x using the base - e logarithms.
Applying the log rule that if
then 
Thus, we get;

Applying the log rule,
, we get;

Expanding, we get;

Subtracting both sides by
, we get;

Subtracting both sides by
, we get;

Taking out the common term x, we have;



Thus, the value of x is 
Answer:
D. 31
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
That is z with a pvalue of
, so Z = 1.96.
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
A previous study indicated that the population standard deviation is 2.8 days.
This means that 
How large a sample must be selected if the company wants to be 95% confident that the true mean differs from the sample mean by no more than 1 day?
This is n for which M = 1. So





Rounding up, at least 31 people are needed, and the correct answer is given by option D.
