Answer:
the minimum sample size n = 11.03
Step-by-step explanation:
Given that:
approximate value of the population standard deviation 
= 49
level of significance ∝ = 0.01
population mean = 38
the minimum sample size n = ?
The minimum sample size required can be determined by calculating the margin of error which can be re[resented by the equation ;
Margin of error = 
n ≅ 11.03
Thus; the minimum sample size n = 11.03
Okay to have a complete triangle with 3 angles it must add up to 180° So therefore if you have 30° For each angle which adds up too 90°. We're are still missing 90 more degrees. So that means we can't make a triangle at all.

Answer:
20
Step-by-step explanation:
617/28= 22 (rounded too)
617/32= 19 ( rounded too)
19-22 is teh amount of classes that can be filled with 28 to 32 students.
20 is correct because it is around the amount of classes that there can be. !4 is too little so the number of students should be smaller.
30 and 60 classes are to big. there would only be about 10 or 20 kids per class
Answer:
Using the Pythagorean Theorem:
15^2 = 12^2 + base^2
base^2 = 225 -144
base^2 = 81
base = 4
