Answer:
The 99% confidence interval is between 62.36%(lower bound) and 89.64%(upper bound).
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 
.
A sample of 65 students from the freshmen class is used and a mean score of 76% correct is obtained.
This means that 
99% 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:
0.6236*100 = 62.36%
0.8964*100 = 89.64%
The 99% confidence interval is between 62.36%(lower bound) and 89.64%(upper bound).
The answer is rotation then translation. (:
Answer:If you are using a calculator, simply enter 770×100÷70, which will give you the answer.

Answer:
B
Step-by-step explanation:
In this problem we have points of the form (x^0,y^0) cama Y0 what we must do is replace it of appointing a function Y = 3^x replace x^0 with x and y^0 with 1. The point belongs to the function only if the right side of the equality is equal to the left side
Answer:i believ the its the last one
Step-by-step explanation:
For end behaviour, note the leading coefficient and the degree. The degree is odd and the leading coefficient negative, hence it would rise to the left and fall to the right.
