Answer:
The 90% confidence interval is 0.575 to 0.625.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.
In which
Z is the zscore that has a pvalue of .
For this problem, we have that:
90% confidence interval
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 90% confidence interval is 0.575 to 0.625.
<span>y = –2x + 5
–5y = 10x + 20
replace </span>y = –2x + 5 into –5y = 10x + 20
–5( –2x + 5 ) = 10x + 20
10x - 25 = 10x + 20
-25 = 20...can't be...
answer is <span>D. no solution</span>
Both the original and the inverse are functions because for each value of C there is a unique value of F and vice-versa.
i.e.
<span>B. Original is a function; inverse is a function </span>
