You can not reduce that number because you can not divide 32 by 3 because it would just be a decimal and you can't do that
Answer: Midpoint= -13/2, -4
Step-by-step explanation:
Midpoint formula is (X1+X2)/2, (Y1+Y2)/2
So.
1. (-7+(-6))/2, (-7+(-1))/2
2. That equals -13/2,-4
Answer:
A. P(success/age≥60) = 12.5%
B. Yes, the success is independent of age.
Step-by-step explanation:
Probability of success, given that a climber is at least 60 years old is calculated using conditional probability rule
P(A|B) = P(A n B)/P(B)
Probability of success given that a climber is at least 60 years old is given by
P(success|age≥60) = P(success n age ≥ 60)/P(age ≥ 60) = 0.005/0.04
= 0.125
P(success|age≥60) = 12.5%
B. The success is independent on age
