Answer:
The calculated 99% confidence interval is wider than the 95% confidence interval.
Step-by-step explanation:
We are given the following in the question:
95% confidence interval for the population proportion
(0.65, 0.69)
Let 
be the sample proportion
Confidence interval:
Let x be the standard error, then, we can write
Solving the two equations, we get,
99% Confidence interval:
Putting values, we get,
Thus, the calculated 99% confidence interval is wider than the 95% confidence interval .
Answer:
12x-1
Step-by-step explanation:
step 1: (2 • (3x - 5)) + 3 • (2x + 3)
step 2: 2 • (3x - 5) + 3 • (2x +3)
final result = 12x-1
Answer: 10
Step-by-step explanation:
My answer is correct because, if x=5 then were just multiplying 2 times 5 since 5 is not on the top like 
because if it was that means we have to multiply 2 by itself 5 times. But since its not a exponent you just multiply 2 times 5. And 2 x 5= 10.

Answer:
The Answer is: a^2 + 2ab + b^2
Step-by-step explanation:
Multiply the first factor resulting in the a squared, then the two inner factors resulting in ab + ab, finally the last term, resulting in b squared. Then combine terms:
(-a - b)(-a - b) =
a^2 + ab + ab + b^2 =
a^2 + 2ab + b^2
Hope this helps! Have an awesome day! :-)
