One household is to be selected at random from a town. The probability that the household has a cat is 0.20.2 . The proba

Answer:

There is a 50% probability that the household has a dog, given that the household has a cat.

Step-by-step explanation:

We solve this problem building the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a household has a cat.

B is the probability that a household has a dog.

We have that:

$A = a + (A \cap B)$

In which a is the probability that a household has a cat but not a dog and $A \cap B$ is the probability that a household has both a cat and a dog.

By the same logic, we have that:

$B = b + (A \cap B)$

The probability that the household has a cat or a dog is 0.5

$a + b + (A \cap B) = 0.5$

The probability that the household has a dog is 0.4

$B = 0.4$

$B = b + (A \cap B)$

$b = 0.4 - (A \cap B)$

The probability that the household has a cat is 0.2.

$A = 0.2$

$A = a + (A \cap B)$

$a = 0.2 - (A \cap B)$

$a + b + (A \cap B) = 0.5$

$0.2 - (A \cap B) + 0.4 - (A \cap B) + (A \cap B) = 0.5$

$A \cap B = 0.1$

What is the probability that the household has a dog, given that the household has a cat?

20% of the households have a cat, and 10% have both a cat and a dog. So

$P = \frac{A \cap B}{A} = {0.1}{0.2} = 0.5$

There is a 50% probability that the household has a dog, given that the household has a cat.

A rare coin appreciates at a rate of 5.2% a year. If the initial value of the coin is $500, after how many years will its

Kisachek [45]

Answer: 36 years

Step-by-step explanation:

Exponential equation to represent growth:-

$y=A(1+r)^t$ , where A is the initial value , r is the rate of growth and t is the time period.

Given : A rare coin appreciates at a rate of 5.2% a year. If the initial value of the coin is $500.

i.e. Put A= 500 and r= 0.052 in the above formula.

The amount after t years:

$y=500(1.052)^t$

Inequality for value cross $3,000 mark:

$3000$

Divide both sides by 500

$6$

Taking log on both sides , we get

$\log6\dfrac{0.778151250384}{0.0220157398177}=35.345223773\\\\t\approx36$

Hence, it will take approx 36 years to cross the $3,000 mark.
