Answer:
{7x^2+168x+840}/{x+12}
Step-by-step explanation:
120 is the right answer that is what my teacher told me
I could be wrong, but I would say it's 18.325
The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.
Given:
Random number=10
mean of x=2
population=125
mean of p=2.7
Using this formula
Sampling error=x− μ
Where:
x= sample mean=2
μ=population mean=2.7
Let plug in the formula
Sampling error=2-2.7
Sampling error=-0.7
Inconclusion the sampling error is A.-0.7.

Answer:
87% full
Step-by-step explanation:
<u>To find the solution:</u>
- Use the equation p·x=y where x = 13,920 and y = 16,000
- Since you are trying to find the percent, divide both sides of the equation by 13,920. p · 13,920(÷13,920) = 16,000(÷13,920)
- The step above cancels out the 13,920 leaving you with the answer. p=0.87
- 0.87 = 87%
