An insurance company is setting out its policy for the next year. The chance that a customer (on average) survives another year
Doss [256]

Answer:

The expected loss is  E  =  $6980

Step-by-step explanation:

From the question we are told that

     The  chance that a customer  survives another year is p =0.96

     The rate at which the policy is sold is   r =  $85 per month

      The rate at which the policy is sold per year is   R =  $85 * 12 per year

                                                                                          = $1020 per year

     The amount paid the the beneficiaries is  A =$200,000

The expected value of profit/loss for this company is mathematically represented as

            E  =  R -[ (1-p)*A]

substituting values

            E  =  1020 -[ (1-0.96)*200000]

             E  =  1020 -8000

             E  =  - $6980

The negative sign shows that it is a loss

Your job is to figure out how to make a "silver mile". Here in the United States we could do this with nickels, dimes, quarters,
Ludmilka [50]

The total value of coins to create a silver mile following the specific rules stated is $38,114.18

<h3>Distance left:</h3>

63360 - 31650.48 = 31679.52 inches

A third of the distance is missing: 10559.84 inches

  • Diameter of the half-dollar: 1.205 in

This means 10,559.84 inches/ 1.205 in = 8763.35 rounded to 8764

Total distance coverd 8,764 x 1.205 in = 10560.61

Total distance left: 31679.52 - 10560.61 = 21118,91 / 4 = 5279.72

  • Diameter of quarters: 0.750 inches

This means 5279.72 / 0.750 =7039.62 rounded to 7040

7040 x 0.750 = 5280

Total distance left = 21118,91 -  5280 = 15,838.91 / 5 = 3167.782

  • Diameter of dimes: 0.705

This means 3167.82 / 0.705 = 4493.36 rounded to 4494

0.705 x 4494 = 3168.27

Total distance left = 15,838.91 - 3168.27 = 12670.64

  • Diameter of the nickel: 0.835

This means 12670.64/ 0.835 = 15174.41 rounded to 15175

<h3>How much money was used?</h3>

For this change the coins to dollars:

Susan B. Antony Silver dollars: 30462 = $30462

Half-dollars: 8764 = $4382

Quarters: 7040 = $1760

Dimes: 4494 = $561.75

Nickels: 15175 = $948.43

Total: $38114,18
