Suppose you have a wallet with $5 bills, $10 bills, and $20 bills. If the probability of picking a $20 bill is 4/15, and the probability of picking a $20 bill is 4/15, and the probability of picking a $5 bill is 1/3, what is the probability of picking a $20 bill?

Answers

The question does not make any sense. The probability of a 20 bill has already been given.

Given:
$5 bills
$10 bills
$20 bills

probability of $20 is 4/15
probability of $5 is 1/3

numerator is the number of events
denominator is the number of outcomes

the missing probability is of the $10 bill.

4/15 + 1/3 + x = 1 or 15/15

$5 bill = 1/3 x 5/5 = 5/15

15/15 - 4/15 - 5/15 = (15-4-5)/15 = (15-9)/15 = 6/15 = 2/5

the probability of $10 is 2/5


Answer:

The problem isn't copied out correctly. the first $20 should be $10

Step-by-step explanation:

5x=2x-15
y=2x-15
and y=5x

Answers

5x = 2x-15
3x = -15
x = -5

substitute x = -5 into one of your equations
so y = 5x becomes y = 5 x -5
y= -25

x=-5 and y=-25
5x=2x-15 =  x=-5

4 (x - b) =x

Answers

4 (x - b) = x            Use the DIstributive Property [(4(x) - 4(b)]
4 x - 4b = x            Add 4b to both sides
         4x = 4b + x   Subtract x from both sides
         3x = 4b         Divide both sides by 3
           x = (4b)/(3)

What is the maximum value of the cube root parent function on −27 ≤ x ≤ 0?

Answers

Answer:

0

Step-by-step explanation:

Given an interval -27≤x≤0, to get the cube root of the maximum value, first we need to know the maximum value in the range. The maximum value between -27 and 0 will be 0 which is the greatest value in that interval.

Since the cube root of 0 is 0, the cube root of the maximum value within that range is 0.

The answer should be B.0.
