507 i think. you just square 13 then multiply that by pi which is 3
Answer:
Original price= $3,200
Step-by-step explanation:
Giving the following information:
Purchase price= $2,816
Discount rate= 12% = 0.12
<u>To calculate the original price, we need to use the following formula:</u>
Original price= purchase price / (1 - discount rate)
Original price= 2,816 / 0.88
Original price= $3,200
I'm not 100% sure on this. I think it's 23.
Answer:
...
Step-by-step explanation:
14, 18, 20
There are a total of 8 balls
The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4
Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14
