23 and 29 are the two numbers that are prime
We can solve this problem by referring to the standard
probability distribution tables for z.
We are required to find for the number of samples given the
proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value
of z equivalent to:
z = 1.96
Since the problem states that it should be within the true
proportion then p = 0.5
Now we can find for the sample size using the formula:
n = (z^2) p q /E^2
where,
<span> p = 0.5</span>
q = 1 – p = 0.5
E = estimate of 5% = 0.05
Substituting:
n = (1.96^2) 0.5 * 0.5 / 0.05^2
n = 384.16

Step-by-step explanation:
A pint has 2 cups
2 cups = 1 pint
1 cup = 1/2 pint
1/4 cup = 1/2 ÷ 4 = 1/2 * 1/4 = 1/8 pint
Answer:
6.4 minutes ( or 6 minutes and 24 seconds)
Step-by-step explanation:
Filling up the jug means the empty space is 0, hence V = 0.
<em>We plug in 0 into V and solve for t to get the time required to fill it up:</em>
Hence it will take 6.4 minutes to fill up the jugs.
<u>Note:</u> 0.4 minutes in seconds is 
seconds
