We can use cluster sampling here. In this case, the population is divided into sampling units or clusters, for example, zone within educational or geographical areas. Having divided the population into clusters, we can use simple random sampling to select the clusters to be examined. Consider Asian American as one cluster, African american as another cluster and so on. According to the size of the cluster randomly select individuals from each cluster for a total of 100 individuals.
Generally there would be bias in accordance to the differnce in ethnicity. Also if the selected students are in a younger, then the teachers opnion would play a very big role there.
The question itself is a source of bias and it seems to give an idea to the students to think in these lines. The question can be better worded to get a correct answer. Even if there is equal opportunity, some students may read the question and give a negative answer.
Answer:
A. 84 cubic inches
Step-by-step explanation:
Volume = volume of triangular prism + volume of rectangular prism
✔️Volume of triangular prism = ½*b*h*l
b = 4 in.
h = 4.5 in.
l = 4 in.
Volume of triangular prism = ½*4*4.5*4 = 36 in.³
✔️Volume of rectangular prism = L*W*H
L = 4 in.
W = 4 in.
H = 3 in.
Volume of rectangular prism = 4*4*3 = 48 in.³
✔️Total volume = 36 + 48 = 84 in.³

Ote: (21/n)n = 21)
Numbers 21/n and n
Question States***
(21/n) = 4n - 5
21 = 4n^2 - 5n
4n^2 - 5n - 21 = 0
(4n + 7) (n - 3) "Find the integers" n = -7/4 will Not work
n = 3 and the other number is 7 21%2F3
Scale in terms of cm to m= 1/5
In every meter there are 5 cm
Considering this, if the dimensions are 15cm and 20cm, you would need to multiply them by 5 to convert them to meters
15*5= 75 20* 5=100
Dimensions- 75ft by 100ft
