400 Hamburgers
600 Hot dogs
Divide 2,400 by two because that's how many items they sold. You'll get 1,200.
Divide 1,200 by 3 because that's how much a hamburger costs and you'll end up with 400
Divide 1,200 by 2 because that's how much a hot dog costs and you'l end up with 600
To check, multiply 400x3 and 600x2
Then add the sums together- 1,200+1,200= 2,400
You made a mistake with the probability 
, which should be 
in the last expression, so to be clear I will state the expression again.
So we want to solve the following:
Conditioned on this event, show that the probability that her paper is in drawer 
, is given by:
(1) 
and
(2) 
so we can say:
is the event that you search drawer 
and find nothing,
is the event that you search drawer and find the paper,
is the event that the paper is in drawer 
this gives us:
Solution to Part (1):
if 
, then 
,
this means that
as needed so part one is solved.
Solution to Part(2):
so we have now that if = , we get that:
remember that:
this implies that:
so we just need to combine the above relations to get:
as needed so part two is solved.
Answer:
b=11.6m
Step-by-step explanation:
If this is a right triangle;
a^2+b^2=c^2
A and B are both LEGS, while C is the HYPOTENUSE
(8.7^2)+b^2=(14.5^2)
b^2=(14.5^2)-(8.7^2)
b^2=134.56
b=plus or minus 11.6
Because length can't be negative, it's +11.6
Used to quantify the rate of energy transfer
