Answer:
x = 10
Step-by-step explanation:
130 = 8x + 50
<u>Step 1: Solve for x</u>
130 - 50 = 8x + 50 - 50
80 / 8 = 8x / 8
10 = x
Answer: x = 10
Yes, they are independent because P(A) ⋅ P(B) = P(A ∩ B)
M/k=x
(m)m/k=x(m)
k=xm
Because you are diving one the side where m/k, you need to multiply m to both sides to get rid of it on one. Therefore, you are left with K=XM
The best way is to completely randomize the people you pick, and get a large array of diverse people. People of different ages, sizes, living in different places. You can do this by gathering all of the people’s phone numbers, randomizing them, then calling quite a few. Make sure you get many people. This way, it will be unbiased.
