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.
Answer:
a =-6
Step-by-step explanation:
4a+5=2+3.5a
Subtract 3.5a from each side
4a-3.5a+5=2+3.5a-3.5a
.5a +5 = 2
Subtract 5 from each side
.5a +5-5 = 2-5
.5a = -3
Divide each side by .5
.5a/.5 = -3/.5
a =-6
745 is the answer
basically,
775 - 15 l-2l (absolute value = positive number)
so
775 - 15 (2)
MULTIPLY -15 X 2 -----> -30
775 - 30
= 745
Answer:
Pretty sure part A is 2t+ 2< $ 56.00
Part B is 10.75 plus 9.50 x 2 = 29.75 60 she can buy 6 dark roast
I don't know how to do it on a graph but I think theres a place called tiger algebra and they plot it for you if you put the equation in
Hope this helps
