Answer:
Equal to.
Step-by-step explanation:
Absolute value is when a number is changed into it's exact opposite, however, the absolute value of any number is always a positive number.
((b+2)(b+12)/(b+2)(b+3))*(b+3)
= (b+12)
Answer:
A sample size of 6755 or higher would be appropriate.
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 M is given by:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
52% of Independents in the sample opposed the public option.
This means that
If we wanted to estimate this number to within 1% with 90% confidence, what would be an appropriate sample size?
Sample size of size n or higher when . So
A sample size of 6755 or higher would be appropriate.
Step-by-step explanation:
The numbers between the squares are the possible answers.
For example, 2/3 ÷ 3/4 is either 1/2 or 8/9.
2/3 ÷ 3/4
2/3 × 4/3
8/9
The answer is 8/9, so you'll move up to the next square.
That's is the commutative property of multiplication
