Answer: Even
Step-by-step explanation:
Look at the ones place of each number, which in this case is 8 and 6.
8 + 6 = 14, which is an even number. This makes the sum of both numbers also an even number.

Answer:
b = 2
Step-by-step explanation:
In order to find the value of b, we have to isolate b on one side of equation first
So,

Multiplying 2 with b-1

Adding 2 on both sides

Dividing by 5 on both sides

So the value of b is 2 ..
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
Answer:
616/2500
Step-by-step explanation: You first have to find the number of times a Blue marbles was chosen: 22
Then find the total number of marbles that were chosen. Make a fraction out of it: 22/50
You then see how many times tails was flipped: 28
Do the same thing again: 28/50
Then multiply the two fractions together:
22/50 * 28/50 = 616/2500
