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
Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
Answer:
$14771055
Step-by-step explanation:
14 times 10= 140ft
140ft in yards is 46.67 in yards
46.67 times 31.65 =14771055
V^2 = 252
v^2 - 252 = 0
(v - sqrt252)(v + sqrt252) = 0
so the 2 solutions are sqrt252 and - sqrt252
= 15.87 and -15.87 to nearest hundredth.
I believe the answer is 38
