Answer: D: 3/8
Step-by-step explanation:
m = y2 - y1 / x2 - x1
Plug in the coordinates into formula.
3(6-4x)-27x+10x-31 =
18-12x-27x+10x-31 distributed. =
-13 - 29x
Answer:
0.0512
Step-by-step explanation:
Probability of making a correct guess ; p = 1 / 5 = 0.2
q = 1 - p = 1 - 0.2 = 0.8
Number of questions, n = 5
Using the binomial probability relation :
P(x = x) = nCx * p^x * q^(n-x)
P(x = 3) = 5C3 * 0.2^3 * 0.8^2
P(x = 3) = 0.0512
Answer:
The sampling technique used is the systematic sampling.
Step-by-step explanation:
Systematic sampling as the name implies is the application of a system so select samples, like having a people in a line, and a system is used to select the sample, like counting one to three and picking every third person in the line. This kind of sampling is bias because everyone is not giving equal opportunity of selection.
