Answer:
3.14 (or pi ) feet
Step-by-step explanation:
Entire circle circumference = pi *d = 8 pi feet
45 degrees is a fraction of the entire 360 degrees of the circle
45 / 360 * 8 pi = pi = 3.14 ft
Answer:
-21
Step-by-step explanation:
because theres two negitives so it makes it a positive
1728 cubic centimeters
12 with the exponent of 3 would basically be 12x12x12 but easier i put 12x12=144x12= which is 1728
cuz if its just 12x12 thats just the area of one side, if its 12x12x12 its the volume of the whole cube/rectangular prism
Answer:
Independent Sampling
Step-by-step explanation:
There are two scenarios for independent sampling .
Testing the mean we get the differences between samples from each population. When both samples are randomly inferences about the populations. can get.
Independent sampling are sample that are selected randomly. Observation does not depend upon value.Many analysis assume that sample are independent.
In this statement 90 dash are divides into two groups Group 1 and Group 2 . Both are standardized that mean both are randomly selected. Means are observed. Observation doesn't depend upon value. So this style of sampling is independent Sample.
