Answer:
For each of the sample sizes given, for the population to be regarded as effectively infinite, student population has to be more than
a) 240 students.
b) 1,040 students.
c) 1,920 students.
Step-by-step explanation:
A population may be treated as infinite when the population size, N, is at least 20 times the sample size, n.
Mathematically,
(N/n) > 20
N > 20n
(a) A sample of 24 students.
If sample size = n = 24
For the population size to be effectively infinite,
N > 20n
N > 20×24
N > 480 students
(b) A sample of 52 students.
If sample size = n = 52
For the population size to be effectively infinite,
N > 20n
N > 20×52
N > 1,040 students
(c) A sample of 96 students.
If sample size = n = 96
For the population size to be effectively infinite,
N > 20n
N > 20×96
N > 1,920 students
Hope this Helps!!!
In this equation your slope is -2 meaning that you are going down 2 over 1 to the right and then you have this +6 which means that is your y intercept
If you want to graph it make your x and y chart and use easy numbers such as -1,0,1. Plot those points to your x from your equation and you should be solving for y
<span>c-b/ 3a 1st, subtract b from both sides, then divide both sides by 3a, the side with X cancels out and leaves you with c-b/3a
