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
Answer:
Acute
Step-by-step explanation:
The last angle is 71 which is less than 90
Answer: 72/48 unless you have to simplify which would be 3/2 or do you want decimal?
Step-by-step explanation:
Answer:
the factors of 12 are 1, 2, 3, 4, 6, and 12. So the greatest common factor of 9 and 12 is 3. So you divide both sides by 3. So the simplest form of 9/12 is 34.
Step-by-step explanation:
hope his correct, .. sorry if not <33
can you mark branliest if right?
You would do 12 divided by 25 which equals 0.48 and keep on doing that the next one is 0.52 and last is 0.53 meaning the best is the 12 muffins
