Machine A working alone can complete a job in 3 1/2 hours. Machine B working alone can do the same job in 4 2/3 hours. How long

SIZIF [17.4K]

Answer:

B) 2 hours

Step-by-step explanation:

If machine A complete a job in 3 1/2 hours or 7/2 of an hour

means that in one hour finished 1÷ 7/2 or 2/7

If machine B complete a job in 4 2/3 hours or 14/3 of an hour

means that in one hour finished 1÷ 14/3 or 3/14 of an hour

Then the two machines working together in one hour will make

2/7 + 3/14 = (4 + 3)/ 14

or 7/14 = 1/2

half of the job. Therefore these two machines working together will take two hours

In a city, 60% of the residents live in houses and 40% of the residents live in apartments.Of the people who live in houses, 20%

DIA [1.3K]

Answer:

0.75 or 75%

Step-by-step explanation:

The probability that a resident lives in a house and owns their own business is:

$P(H\cap B)=0.6*0.2\\P(H\cap B)=0.12$

The probability that a resident lives in an apartment and owns their own business is:

$P(A\cap B)=0.4*0.1\\P(A\cap B)=0.04$

Therefore, the probability that a person lives in a house, given that they own their own business is:

$P(H|B) = \frac{P(H\cap B)}{P(H\cap B)+P(A\cap B)}\\P(H|B) = \frac{0.12}{0.12+0.04} \\P(H|B) = 0.75$

The probability is 0.75 or 75%.
