Suppose you have 20 tiles with the numbers 1-20. The theoretical probability that a tile chosen at random is a 5 is 1/20. If you

pick a tile randomly 20 times, replacing the tile each time, will you get a 5 once? Explain.
Can y'all help me with this? Probability is not my strong suit =/
Thanks! =D

Number of tiles = 20

Theoretical Probability (5) = 1/20

If you picked 20 times:

1/20 x 20 = 1

Answer: There is a probability that you will pick 5 once.

A firm has a beta of 1.3 and a debt-to-equity ratio of .4. The market rate of return is 11.6
Citrus2011 [14]

Beta= 1.3

Debt to equity ratio= 0.4

Market rate of return= 11.6%

= 11.6/100

= 0.116

Tax rate= 32%

= 32/100

= 0.32

Risk free rate=  3.3%

= 3.3/100

= 0.033

Pretax cost of debt= 7.2%

= 7.2/100

= 0.072

The firm's WACC can be calacluated as follows

RS= 0.033+1.3(0.116-0.033)

= 0.033+1.3(0.083)

= 0.033+0.1079

= 0.1409

WACC= (1/1.4)(0.1409)+(2/1.4) (0.072)(1-0.32)

= (0.7142)(0.1409) + (1.4285)(0.072)(0.68)

= 0.1006+0.0699

= 0.1705(100)

= 17.05%

Hence the firm's WACC is 17.05%

5 In a scale drawing of an airplane, 1 inch equals 3 meters. The length of the actual plane is 17 meters. What is the length of
Whitepunk [10]

Answer: 5 2/3 inches

Step-by-step explanation:

From the question, we are informed that the scale drawing of an airplane is:

1 inch = 3 meters.

Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:

= 17/3

= 5 2/3 inches

Scott likes to run long distances. He can run 20 km in 85 minutes. He wants to know how many minutes (m) it will take him to run
melisa1 [442]

Answer:

221 minutes

Step-by-step explanation:

52 divided by 20 would be 2.6 then you take the 85 and mulitpy it by 2.6 because 52 is 2.6 times more than 20. so 85 times 2.6 would be 221 minutes.

A car and truck are 540 miles apart. The two vehicles start driving toward Each other at the same time. The car drives at a spee
mina [271]

Answer:they would meet after 4.5 hours

Step-by-step explanation:

At the point where they will both meet, they would have covered a total distance of 540 miles.

Let t represent the time it will take the car and the truck to meet.

Distance = speed × time

The car drives at a speed of 65 miles per hour. Distance covered by the car in t hours would be

65 × t = 65t

The truck travels at a speed of 55 miles per hour.

Distance covered by the truck in t hours would be

55 × t = 55t

Therefore,. 65t + 55t = 540

120t = 540

t = 540/120 = 4.5 hours
