Answer:
Option d.
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 
.
The margin of error is:
79 percent of adults age 18 years and older in the United States use the Internet.
This means that 
98% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Which of the following should be used to find the sample size (n) needed?
We have to find n for which 
So the equation is:
Option d.
Answer:
FALSE

Answer: 28x+30
Explanation: we divide (3x^3-2x^2+4x-3) by (x^2+3x+3) Using long division
3x-11
___________________
(x^2+3x+3) 3x^3-2x^2+4x-3
-(3x^3+9x^2+9x)
__________________
-11x^2-5x-3
-(-11x^2-33x-33)
____________
28x+30
So our remainder will be 28x+30
For the first problem, your answer is D, 16, because -5+8=3, and 3+ |-13|=16, because the absolute value of -13=13
for the 2nd, B is the correct answer. -4.37 is smaller than -1.63,
the 3rd one is C, 19. -14+19=5,
the 4th one the answer is D, -20.1 because 12.7+ -20.1=-7.4
1=D
2=B
3=C
4=D
Each would be 20 cents.
So why did he change his mind about the apples?
