42 + 5 * 32 - 42 ÷ 23
I am going to use the PEMDAS order. Parenthesis, Exponents, Multiply, Divide, Add, Subtract
Multiply ⇒ 5 * 32 = 160
42 + 160 - 42 ÷ 23
Divide ⇒ - 42 / 23 = -1.83
42 + 160 - 1.83
Add ⇒ 42 + 160 = 202
202 - 1.83
Subtract ⇒ 202 - 1.83 = 200.17
42 + 5 * 32 - 42 ÷ 23 = 200.17

Answer: The simplified version of this is 14d²c³√66
Step-by-step explanation:
Answer:
The sample size needed is 2401.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error of the interval is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use 






The sample size needed is 2401.
