Answer:
In the first problem, the value of x is 13.85
Step-by-step explanation:
To find this, we can use the Pythagorean Theorem. This allows us to use the length of the legs (a and b) to determine the length of the hypotenuse (c) .
a^2 + b^2 = c^2
5.3^2 + 12.8^2 = c^2
28.09 + 163.84 = c^2
191.93 = c^2
13.85 = c
Answer:
C.25
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 
.
So it is z with a pvalue of 
, so 
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.
Which of the following is the smallest sample the company can take to achieve the desired margin or error?
This is n when 
We have to round up.
So the correct answer is:
C.25
segment addition postulate
sum is the same
