Answer:
Your answer is 40%
Step-by-step explanation:
It is 20 units between Z and B.
We add 2 more points, and one of them is at the the halfway point of the entire line.(M)
One of them is only 2 units away from B.(N)
That means our line is halved, so from 20/20 possible places a point could go and land in the right area is now 10/20.
Minus 2 from that; to take into count of the N to B, and you have 8/20
8/20 is just 40%
D, it decreases by 6 every time while the others are multiplied by number
1) -1/20
2) -1
3) 1/16
4) 15
5) 19
6) 1/2
7) 19
8) -13
9) -19
10) 1

Answer:
865
Step-by-step explanation:
We have that in 95% confidence level the value of z has a value of 1.96. This can be confirmed in the attached image of the normal distribution.
Now we have the following formula:
n = [z / E] ^ 2 * (p * q)
where n is the sample size, which is what we want to calculate, "E" is the error that is 2% or 0.02. "p" is the probability they give us, 5 out of 50, is the same as 1 out of 10, that is 0.1. "q" is the complement of p, that is, 1 - 0.1 = 0.9, that is, the value of q is 0.9.
Replacing these values we are left with:
n = [1.96 / 0.02] ^ 2 * [(0.1) * (0.9)]
n = 864.36
865 by rounding to the largest number.
