Answer:
107810
Step-by-step explanation:
You can use the order of operations! So we start with 99^3/9. That is 99^2*11. So now let’s do 99/99, it’s 1. So 99^2*11 is 107811, so the answer is 107810.
Answer:
There are 12 students in each group
Step-by-step explanation:

48/4= 12
Hope this helped. ;)
Margin of error = +/- Z*SD/sqrt (n)
Where, Z = 1.96 at 95% confidence interval, SD =standard deviation = 589 dollars, n= sample size (to be calculated)
For the values given;
132= 1.96*589/Sqrt (n) => Sqrt (n) = 1.96*589/132 = 8.7458 => n= 8.7458^2 = 76.49
Rounding up to near a person, n (sample size)= 77 students
That would be : (171 + x) / 2
Remember, the formula for circumference is c = πd. If your diameter is 8 inches, then your circumference is 8π inches.
