Did the test and past the grade your in
Replace f(x) with f(3)
f(3) = -3x - 2
This means that you replace any x values with 3
f(3) = -3(3) - 2
Now solve. Multiply first then subtract
f(3) = -9 - 2
(f3) = -11
Simple...
you have:
The best you can do here is simplify the root--->>
You must find a number that is a perfect square--->>
As we know 4 is a perfect root
leaving you with....
Thus, your answer.
Answer:
The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
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:
95% confidence level
So , z is the value of Z that has a pvalue of , so .
72% of Americans said that they had at least one credit card
This means that
Give the 95% margin of error for this estimate.
The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
104??? Don't you mean 10^4?
<span>2.3 x 10^4 times 3 million is 6.9*10^(4+6) = 6.9*10^10 answer</span>
