Answer:
And rounded up we have that n=421
Step-by-step explanation:
We know that the sample proportion have the following distribution:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 90% of confidence, our significance level would be given by
and
. And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
We assume that a prior estimation for p would be
since we don't have any other info provided. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=421
Answer:
I'm sure it is 180 degrees
Answer: y=38
x=38
z=109
Step-by-step explanation:
because
sorry i dunno i really dont i just need to finish my test lol
I'd say Isaiah Canaan or Kevin Love, Isaiah has quick reflexes and can keep up with the pace of the game, Kevin is basically assurance for anyone that they can land in the greenzone
