0.15 as fraction or multiply 3/8 and 2/5
105 m = 2.5 h
x miles = 1 hour
You cross multiply since it's a proportion:
2.5 * x
105 * 1
=
2.5x = 105
Then you divide everything by 2.5
The answer is 42
Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
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 z-score that has a p-value of 
.
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that 
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
The first missing number in the sequence is 35, and the last missing number is 77.
<h3>Next number of the given sequence</h3>
The two missing numbers in the given sequence is calculated as follows;
= ? 49 63 ?
The given sequence is factor 7 which increases by 2
= 7 x 5 7 x 7 7 x 9 7 x 11
= 35 49 63 77
Thus, the first missing number in the sequence is 35, and the last missing number is 77.
