Answer:
A sample of 179 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
.
That is z with a pvalue of
, so Z = 1.44.
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 found that for an average family the variance is 1.69 gallon?
This means that 
If they are using a 85% level of confidence, how large of a sample is required to estimate the mean usage of water?
A sample of n is needed, and n is found for M = 0.14. So






Rounding up
A sample of 179 is needed.
Answer:
5 units to the right.
Step-by-step explanation:
The x in f(x) is replaced by x - 5 to give g(x).
The - 5 will shift f(x) 5 units to the right.
Answer: The equation is 16g+6 ,lmk if you need the answer :)
Step-by-step explanation:
64, 500 x 0.8%=65,016.00. He automatically earns $1250.00 a month
add the 65, 016.00 + 1250.00 and the answer would be 66 266.00
