Answer:
The method for selecting a stratified sample is to order a population in some way and then select members of the population at regular intervals. - FALSE.
This can be re written as :The method for selecting a systematic sample is to order a population in some way and then select members of the population at regular intervals.
Explanation for stratified sampling:
In stratified sampling, the members of a population are divided into two or more strata with similar characteristics and then a random sample is selected from each strata. This way ensures that members of each group within a population will be sampled.
Explanation for cluster sampling:
The method for selecting a cluster sample is to order a population in some way and then select members of the population at regular intervals.
In cluster sampling, the population is divided into clusters, and all of the members of one or more clusters are selected.
Answer:
z= 38°
Step-by-step explanation:
z= 90(from right angle)+52=142
180-142=38°
To solve this, you have to know the formula for the area of a trapezoid:
In this question:
base 1 = 25
base 2 = 35
height = 12
The area is
360
Answer and Step-by-step explanation:
Area (A) = 153
Length (l) = 8 + w
Width (w) = w
A = lw
153 = (8 + w)(w)
153 = 
0 = - 153
(w - 9)(w + 17)
w = 9
w = -17
We can't have a negative length, so we only use 9.
w equals 9.
That means l equals 17 (9 + 8 = 17).
Length = 17
Width = 9
