It takes 4 minutes to fil an empty aquarium to a depth of 2/4 meters. what is the unit rate in minutes per meter ? write your an

Kruka [31]

The unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.

We have,

Time taken to fill an aquarium to a depth of $\frac{2}{4}$ m = 4 minutes,

So,

Time = 4 minutes,

And,

Depth = $\frac{2}{4}$ m,

Now,

The unit rate in minutes per meter,

So,

We will Now convert given depth fraction,

i.e.

Depth = $\frac{2}{4}$ = 0.5m,

So,

It takes 4 minutes to fill a half meter,

Then,

To fill a meter it will take = $\frac{4}{\frac{2}{4} }$ = 8 minutes

So,

The unit rate in minutes per meter is 8 minutes per meter.

Hence we can say that the unit rate in minutes per meter for filling the given aquarium to a depth of 2/4 meters will be 8 minutes per meter.

In a survey of a town, 56% of residents own a car, 21% of residents owns a truck, and 4% of residents own both a car and a truck

rodikova [14]

Answer:

A. 7%

Step-by-step explanation:

We build the Venn's diagram of these probabilities.

I am going to say that:

A is the probability that a resident owns a car.

B is the probability that a resident owns a truck.

We have that:

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

In which a is the probability that a resident has a car but not a truck and $A \cap B$ is the probability that a resident has both a car and a truck.

By the same logic, we have that:

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

4% of residents own both a car and a truck.

This means that $A \cap B = 0.04$

56% of residents own a car

This means that $A = 0.56$ . So

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

$0.56 = a + 0.04$

$a = 0.52$

What is the conditional probability that a person who owns a car also owns a truck?

$P(B|A) = \frac{A \cap B}{A} = \frac{0.04}{0.56} = 0.07$

So the correct answer is:

A. 7%
