Answer:
5/8 of a cup
Step-by-step explanation:
What you do is you add 1/2 and 3/4 together.
1/2+3/4=5/4.
Noel used half of 5/4 so you would multiply it by 1/2
5/4*1/2=5/8 is your answer.
Answer: That’s weird I don’t see an option for the answer I got, I’m positive it’s correct though. It’s 24/25 or 0.96 in decimal form
Step-by-step explanation:
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:
Solutions are x =4 and y = 1
Step-by-step explanation:

In this equation substitute
, we get

now substitute y =1 in x equation,

Solutions are x =4 and y = 1
-1/4 the negative reciprocal of the slope of the red line
