Answer:
The answer is: -3
Step-by-step explanation:
The expected value is given by adding the values of posible gain mutiplied by the probability of getting that gain so you lose the $4 you pay to play the game with probability 1-1/100=99/100 and you gain 100-4=96 dollars if you win with probability 1/100, so
![E(X)=(-4)\dfrac{99}{100}+(100-4)\dfrac{1}{100}=-3](https://tex.z-dn.net/?f=E%28X%29%3D%28-4%29%5Cdfrac%7B99%7D%7B100%7D%2B%28100-4%29%5Cdfrac%7B1%7D%7B100%7D%3D-3)

answer:
8 pennies,16 dimes,13 nickels,13 quarters
Step-by-step explanation:
total number of coins = 50
16% are pennies
16% of 50
16/100 x 50=(16x50)/100=800/100=8
Pennies = 8
32% are dimes
32% of 50
32/100 x 50=(32x50)/100=1600/100=16
Dimes = 16
5 more nickels than pennies
Pennies = 8
nickels = 8 + 5 = 13
nickels = 13
8+16+13=37
50 - 37 = 13
13 quarters
pennies = 8, dimes = 16, nickels = 13, quarters = 13
8.5X60 = 510 feet/min
510X60 = 30,600 feet/hour
