Answer:
The minimum sample size is n = 75 so that the desired margin of error is 5 or less.
Step-by-step explanation:
We are given the following in the question:
Population variance = 484
Standard deviation =
Confidence level = 0.95
Significance level = 0.05
Margin of error = 5
Formula:
Margin of error =
Putting values, we get
Thus, the minimum sample size is n = 75 so that the desired margin of error is 5 or less.
41 students
-
304: total students
17: riding in car
7: number of buses
-
304 - 17 = 287
287 divided by 7 = 41
Start off by adding 33 + 6 which is 36 and so that’s how you find what d equals
1 batch need 3/4 gallon of milk
She has 1/4 gallon cup
(3/4) divided by (1/4)
A technique in math is just flip the divider which is (1/4) to (4/1)
so it becomes (3/4) multiply (4/1) = (3x4) / (4x1) = 12/4 = 3 times for one batch
She needs three batches so 3 x 3 = 9 times to fill the measuring cup to make all 3 batches of milkshake.
