Answer:
B all real numbers greater than 0
Answer: 28
EXPLANATION:
16 ÷ 64 = 4
7 x 4 = 28
Answer:
The estimate of a population proportion is approximately 541.
Step-by-step explanation:
We can solve the the problem by using the formula for minimum sample needed for interval estimate of a population proportion which is given by the formula
n = pq ((Z/2) / E)^2
As, p is not defined so we use the standard p and q which is 0.5 and 0.5.
The reason for this is we have to choose form 0.1 to 0.9 both values of p and q, we will find the maximum value of pq occurs when they both are 0.5.
Next, we will find the value of (Z/2) by looking at the Z-table, we will find that at 98% confidence (Z/2) = 2.326. Now we start substituting the values in the above formula
n = (0.5)×(0.5) × (2.326/0.05)^2
n = 541.027
n ≅ 541.
(5•4)-8 the answer is 12 because 5 times 4 is 20. Then 20 minus 8 is 12.
3.124 * 10^-4
since your decimal is coming forward you need the exponent to be negative
