A man starts at the point O on the map below. He chooses a path at random and follows it to point B1, B2, or B3. From that point

, he chooses a new path at random and follows it to one of the points A1 – A7. Suppose the man arrives at point A4, but it is not known which route he took, what is the probability that he passed through each of the three points: B1, B2, B3? Calculate each one.

Answer: 1 / 27

Step-by-step explanation: p (B1) = 1 / 3

p (B2) = 1 / 3

p (B3) = 1 / 3

pro (B1 X B2 X B3) = 1 / 3 X 1 / 3 X 1 / 3 = 1 / 27

Jorden drives to the store at 30 miles per hour. On her way home she averages only 20 miles per hour. If the total driving time
Trava [24]
For this case we have the following definition:
 d = v * t

 Where,
 d: distance
 v: speed
 t: time
 Clearing the time we have:
 t = d / v

 The total driving time takes half an hour:
 t = d / v1 + d / v2

1.5 = d / 30 + d / 20
 Clearing d we have:
 1.5 * 30 * 20 = 20d + 30d

1.5 * 30 * 20 = 50d

d = (1.5 * 30 * 20) / (50)

d = 18 miles
 Answer:
 
she lives 18 miles far from the store

If a company’s equity is $340,000 and liabilities are $195,000, what is the value of the company’s assets?
rewona [7]
For this case, the first thing you should keep in mind is the following definition:
 equity = assets - liabilities
 Therefore, by clearing we have:
 assets = <span>equity</span> - liabilities
 Substituting values we have:
 assets = (340000) - (195000)
 assets = $ 145,000
 Answer:
 
The value of the company's assets is:
 
assets = $ 145,000

muminat
In a large population, 61% of the people are vaccinated, meaning there are 39% who are not. The problem asks for the probability that out of the 4 randomly selected people, at least one of them has been vaccinated. Therefore, we need to add all the possibilities that there could be one, two, three or four randomly selected persons who were vaccinated.

For only one person, we use P(1), same reasoning should hold for other subscripts.

P(1) = (61/100)(39/100)(39/100)(39/100) = 0.03618459
P(2) = (61/100)(61/100)(39/100)(39/100) = 0.05659641
P(3) = (61/100)(61/100)(61/100)(39/100) = 0.08852259
P(4) = (61/100)(61/100)(61/100)(61/100) = 0.13845841

Adding these probabilities, we have 0.319761. Therefore the probability of at least one person has been vaccinated out of 4 persons randomly selected is 0.32 or 32%, rounded off to the nearest hundredths.
