Answer:
b= 5
c = 10, x=7 hypotenuse = 7
Step-by-step explanation:
A 30-60-90 triangle has the ratios of x-x-2x so if x=5, then 5-5 - 10
for a 45-45-90, if one leg is 7, so is the other x so hypotenuse is 7
Answer:
B
sqrt of 1000= 31.6m
A=pi r2
1000pi= pi r2 (pi cancels)
1000=r2 (take square root of both sides)
r= 31.6m

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
