Answer:
n=1705
Step-by-step explanation:
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Assuming the X follows a normal distribution
And the distribution for
is:
We know that the margin of error for a confidence interval is given by:
(1)
The next step would be find the value of
,
and
Using the normal standard table, excel or a calculator we see that:
If we solve for n from formula (1) we got:
And we have everything to replace into the formula:
And if we round up the answer we see that the value of n to ensure the margin of error required
mm is n=1705.
Answer:
y=4x+47
I wanted to wait for the person who originally said the answer but it's been a while and I kinda want the points. Sorry
Answer:
4/3
Step-by-step explanation:
reduce the fraction by a factor of 6
pretty sure you mean write 24/18 in simplest form so that's the answer
Hope this helps! :)
(2x+3)*4 is less than or equal to 10. For x, the number, you would get x is greater than or equal to -1/4.
