Answer:
<u>d. divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group</u>
<u>Step-by-step explanation:</u>
Remember, a cluster represents a selection out of a group belonging to a larger population. Thus, cluster sampling includes the steps;
- <u> divide the population into groups;</u>
- <u>use simple random sampling to identify a proportionate number of individuals from each group.</u>
For example, A bus company wants to survey all its customers for a particular day, using cluster sampling, they will randomly select 10 trips that day and survey some or all the passengers on those trips.
Answer:
8, 64, 512, 4096

=====================================================
Work Shown:
P = 10,000 = deposit
r = 0.04 = decimal form of 4% interest rate
n = 4 = we're compounding 4 times a year
t = 5 years
-------------
A = P*(1+r/n)^(n*t) .... compound interest formula
A = 10,000*(1+0.04/4)^(4*5)
A = 12,201.9003994797
A = 12,201.90
After 5 years, there is $12,201.90 in the account.
This is assuming you do not deposit any more money, and it also assumes that you don't take any money out during the 5 year timespan either.
The diameter of the wheel is 30 inches, therefore the radius is 15 inches.
We calculate the angular velocity (w) of this using the formula:
w = v / r
w = 60 mph / 15 inches = 4 mph / inches
Since the flange is 1 inch beyond the rim, hence the effective radius for this is 16 inches.So the velocity on the outer edge is:
v = w r
v = (4 mph / inches) * 16 inchesv = 64 mph
Answer:
x = 2
Step-by-step explanation:
55-42=13
13 brought up to 14 so it can be divided by 7
14 / 7 = 2
