I am not sure but I would have to guess 46 because it is the closest to 19
Answer:
(b)
We can use an estimatior for the population proportion as
since we don't know previous info. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Step-by-step explanation:
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 the confidence level is 99%, 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)

Answer:
z varies jointly with y and the square of x.If z= 252 when y= -7 and x= -3 , find z when x = -2 and y= 2
Answer:
i think its D. i might be wrong sorry.

Answer:
k is 16 so now u would plug it in.
Step-by-step explanation:
3 is 65 and 9 is 65 because they are alternate interior angles
