Answer:
A- 0.125
B- Success of climbing mount Everest is independent of age.
Step-by-step explanation:
A.
Let x denote success in climbing Mount Everest
Let y denote the climber is at least 60 years old.
Therefore,
P(x) = 0.31
P(y) = 0.04
P( x ∩ y) = 0.005
Probability of success when the climber is at least 60 years old =
P( x ∩ y) ÷ P(y) = 0.005 ÷ 0.04 = 0.125.
B.
The success rate is independent of age as there are both success and failure rates across board on the scale of ages of climbers.
The answer is c F(x)= x2-5 and g(x)=c+4
The answer is simply all you do is subtract 72 from 97 and you'll have the answer which is 25, so the temperature decreased by 25 degrees
Answer:
72
Step-by-step explanation:
70-(-2)=70+2=72
