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

What is 18x-9(x-1)=5(3x+3)

Answers

Answer:

-4

Step-by-step explanation:

18x - 9(x - 1) = 5(3x + 3)

Step 1: Distribute

18x - 9x - 9 = 15x + 15

Step 2: Combine like terms

9x - 9 = 15x + 15

Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side

9x - 9 = 15x + 15

-9x -9x

-9 = 6x + 15

-15 -15

-24 = 6x

/6 /6

-4 = x

What is the surface area of the figure? A. 408 ft2 B. 458 ft2 C. 545 ft2 D. 720 ft2

Answers

There are 2 faces 7 x 5

$2*(5*7)=2*35=70ft^2$

There 2 faces 5 x 5

$2*(5*5)=2*25=50ft^2$

there are 3 faces 5 x 12

$4*(5*12)=4*60=240ft^2$

There are 2 faces 7 x 7

$2*(7*7)=2*49=98ft^2$

Now only we have to sum all of them together

$98+240+50+70=458ft^2$
