Answer:
Multiply 4 by the difference of 10 and 3, then add 5
Answer:
~ 5(x-5)
Explanation:
~ Always find GCF to factorize a number, here it’s 5
~ Now inside the bracket the x stays the same but 25 divided by 5=5
~ Now we have 5(x-5)
Answer:
a) 0.23
b) The 95% confidence interval for the population proportion is (0.1717, 0.2883).
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
.
Point estimate
The point estimate is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval for the population proportion is (0.1717, 0.2883).
Answer: domain: x>-3
range: y > -1
Step-by-step explanation:
Zero is the only thing that makes sense
