Answer:
1 quarter pound = 0.25 of a pound.
Give that:
Total amount of ground beef = pound
From 3.5 pound of beef we have to make burgers using 0.25 pound of beef in one burger
We have to find how many burgers can be made:
We have to divide 3.5 pound by 0.25 pound
i.e,
⇒14 quarter pounds burger can be made.
Therefore, 14 quarter pound burgers can George make out of 3 1/2 pounds of ground beef

Answer:

Step-by-step explanation:
Given that a shuttle launch depends on three key devices that may fail independently of each other with probabilities 0.01, 0.02, and 0.02, respectively.
Required probability = the probability for the shuttle to be launched on time
= Probability that all three do not fail
Since each key device is independent of the other
we have
prob that all three do not fail = 
That is the answer it was to long to write down
I am unsure about the very last problem but I can help with the first two
1) (y+1)+4
If we combine the numbers 1 and 4, we get +5 and can isolate the numbers from the variable.
This would give us

2) (6*r)*7
remember that we do not have to explicitly state 6*r
Instead, we can write it as 6r
this helps us get rid of the parentheses
now we can write it as

I hope this helps!:)
Answer:
f^-1(x) = (x -2)/3
Step-by-step explanation:
To find the inverse function, swap x and y, then solve for y.
y = 3x +2 . . . . given function
x = 3y +2 . . . . inverse relation
x -2 = 3y . . . . subtract 2
(x -2)/3 = y . . . divide by 3
f^-1(x) = (x -2)/3 . . . . in functional form
