Your answer to your question is that it is less than -24
|x - 2x/5| <= 10
|5x - 2x| <= 50
3x <= 50
x <= 50/3
-|5x - 2x| <= 50
-3x <= 50
x >= - 50/3
answer
-50/3 <= x <= 50/3
Answer:
73.9
Step-by-step explanation:
multiply 5.50 by 8 and 14.95 by 2
EDIT: then add the products together
Answer:
A sample size of at least 737 specimens is required.
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 width M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:

So:





A sample size of at least 737 specimens is required.
