The value of p would be 40. This is because the ratio of p:q = 10:5. this could be simplify into p:q = 2:1. Applying the ratio p:20 = 2:1, P=40.
Answer:
We need a sample size of at least 719
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 margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
How large a sample size is required to vary population mean within 0.30 seat of the sample mean with 95% confidence interval?
This is at least n, in which n is found when
. So

Answer:the length of the rectangle is 28
The width of the rectangle is 16
Step-by-step explanation:
The given equations are set up to determine the dimensions of a rectangle. L represents the length of the rectangle. W represents the width of the rectangle. Let us label
2L + 2W = 88 as equation 1.
We would substitute L = W + 12 into equation 1, it becomes
2(W + 12) + 2W = 88
2W + 24 + 2W = 88
4W + 24 = 88
4W = 88 - 24 = 64
W = 64/4 = 16
Substituting W = 16 into L = W + 12, it becomes
L = 16 + 12 = 28
The answer is a fraction 24 over 7 or 24/7
