Answer:
BD = 8.8
Step-by-step explanation:
You have a right triangle.
The hypotenuse is BD
The side opposite the 27o angle is 4
Sin(27) = opposite / hypotenuse.
Sin(27) = 0.45399
opposite = 4
hypotenuse = ?
0.45399 = 4/hypotenuse
BD = 4/0.45399
BD = 8.811
The answer is 8.8
A. 6xy(2x^2y^2-4xy^2)
If you need to multiply 6xy and 2x^2y^2 & 6xy and 4xy^2.
You will get 12x^3y^3-24x^2y^3.
b. Factorization is not complete because 6xy is not the greatest common factor.
c. Complete factor: 12x^2y^3(x-2y).

Answer:
The use of sampling would be best in the following situation:
a. The need for precise information is less important.
Step-by-step explanation:
Sampling:
It is such a process of analysis in which we divide a large proportion of data into smaller proportions called samples to determine the characteristics of that data.
- The option a is correct as in sampling, we take a smaller proportion from a large pool of data so when the precise information is less important, it is a good way to use sampling.
- The option b is not correct as the number of items comprising the population is always large.
- The option c is not correct as the likelihood of selecting a representative is relatively not small rather it is large.
- The option d is incorrect as the use of sampling is not appropriate in all of these situations.
