Let n be the number of expected free throw until she makes the first throw. 

Suppose the number of throws are 10, Then she will make 8 of the 10 throws. On 5 throws, she make 4 (80% of 5) and on 2 throws, she makes 1.6, it means one throw. We deduce that the expected number of free throws until she makes one is 2.

emmasim [6.3K]

Answer:

Step-by-step explanation:

At the lying lemon used car company each salesperson makes $5.75 per hour and receives 6 1/2% commission on sales. Converting

6 1/2% to decimal, it becomes 6.5%

If a Salesperson worked for 8 hours, the amount that he would earn would be

8 × 5.75 = $46

If the salesperson sold a car for $9290, his commission would be

6.5/100 × 9290 = 0.065 × 9290 = $603.85

Total amount that the sales person would earn is

46+ 603.85 = $649.85

Finding Present Value In Exercise,complete the table to determine the amount of money P that should be invested at rate r to pro
valkas [14]

Answer:

Step-by-step explanation:

The principal was compounded monthly. This means that it was compounded 12 times in a year. So

n = 12

The rate at which the principal was compounded is 4%. So

r = 4/100 = 0.04

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. The total amount is given as $100000.

1) When t is 1,

100000 = P(1+0.04/12)^12×1

100000 = P(1+0.0033)^12

100000 = P(1.0033)^12

P = 100000/1.04

P = $96154

2) When t is 10

100000 = P(1+0.04/12)^12×10

100000 = P(1+0.0033)^120

100000 = P(1.0033)^120

P = 100000/1.485

P = $67340

3) When t is 20

100000 = P(1+0.04/12)^12×20

100000 = P(1+0.0033)^240

100000 = P(1.0033)^240

P = 100000/2.2

P = $45455

4) When t is 30

100000 = P(1+0.04/12)^12 × 30

100000 = P(1+0.0033)^360

100000 = P(1.0033)^360

P = 100000/3.274

P = $30544

5) When t is 40

100000 = P(1+0.04/12)^12 × 40

100000 = P(1+0.0033)^480

100000 = P(1.0033)^480

P = 100000/4.862

P = $20568

6)When t is 50

100000 = P(1+0.04/12)^12 × 50

100000 = P(1+0.0033)^600

100000 = P(1.0033)^600

P = 100000/7.22

P = $13850
