Well, 0.03= 3%
So i divided 8.4 by 100 and i got 0.084.
Then I multiplied that by 3 (because 3%) and i got the answer of 0.252
Answer:
Hi!
To solve this we can begin by adding 20 to both sides
30t = 90
Next we divide both sides by 30
t = 3

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:
1/4
Step-by-step explanation:
use PEMDAS first.
P=parenthesis
E=exponents
M= multiplication
D= division
A= addition
S=subtraction
you see a parenthesis so you have to distribute 4 to the variables in the parenthesis. 4 time x is 4x. 4 times 3/2 is 6. after distribution you get 4x+6=7. subtract 6 on both sides. 4x=1. divide 4 on both sides. x=1/4.
