A box contains 14 nickels, 15 dimes and 6 pennies. if a coin is picked at random from the box, what is the average value of the
Sidana [21]

Answer:

$0.0646 is the expected value of the draw.

Step-by-step explanation:

1 nickel = 5 cents

1 dime = 10 cents

1 penny = 1 cent

Total number of coins = 14+15+6=35

Probability that a nickel is selected is = 14/35

Probability that a dime is selected is = 15/35

Probability that a penny is selected is = 6/35

So, the expected value of the draw will be =

\frac{14}{35}*5+\frac{15}{35}*10+\frac{6}{35}*1

\frac{70}{35}+\frac{150}{35}+\frac{6}{35}=\frac{226}{35}

= 6.457 cents ≈6.46 cents

So, in dollars it is = \frac{6.46}{100} = $0.0646

So, $0.0646 is the expected value of the draw.

Answer:

  2.48×10^13 miles

Step-by-step explanation:

There are about (365.25 days)(86400 seconds/day) = 31,557,600 seconds in one year. There are 1609.344 meters in one mile. So, the conversion can be written as ...

  (4.22 ly) (3×10^8 m/s) (3.15576×10^7 s/yr) / (1.609344×10^3 m/mi)

  = 4.22×3×3.15576/1.609344×10^(8+7-3) mi

  ≈ 24.8×10^12 mi

4.22 light years is about 2.48×10^13 miles
