Answer:
It's 10 times larger.
Step-by-step explanation:
If you just have 500,000, and the other one is 50,000, That means 50,000 x 10 is 500,000.
Answer:
-0.008 or -1/15
Step-by-step explanation:
7.) 6 + 9 = 15t - 6 = 9t + 2 = 11t
15t-4
Answer: A.)
8.) f^+2+3
f^5
Answer: A.)
9.)
144^14 = 1.6e30
144^220736
1.6e30/220736 = 7.9e25
/7.9e25 = 144^28
Answer: C.)
Answer:
A sample size of 35 is needed.
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 W as such

In which
is the standard deviation of the population and n is the size of the sample.
How large must the sample size be if the width of the 95% interval for mu is to be 1.0:
We need to find n for which W = 1.
We have that
, then
. So





Rounding up
A sample size of 35 is needed.
