Answer:
Let X be the rectangular distribution
where X is uniformly distribute(3,1)
b=1
a=1
The PMF will be
f(x)=1/b-a
f(x)=1/3-1
f(x)=1/2
f(x)=0.5
Running = 2/3
Swimming = 5/6
5/6 - 2/3 = 5/6 - 4/6 = 1/6
Answer : She spent 1/6 hour longer swimming than running.
Answer:
x = 20/32
Step-by-step explanation:
you have to distribute first.
1) times 4 by all the nubmers and figures inside the pharanthesese and so you get 32x + 20
2) you have to solve for x and so you move the 20 to the other side and get 32x = 20
3) you then divided both sides by 32 to get x by itself and you get x = 20/32
Answer:
-72=-12y-20x
Step-by-step explanation:
-72=2y^2-16y-20x
square the 2 keeping the variable
-72=4y-16y-20x
Then combine like terms in this case the numbers followed by y's
-72=-12y-20x
This is the standard form as there is nothing else you can combine to break this down any further
