A circular mirror has the diameter of 12 inches. what is the area in square inches?

1 answer:

5 0

Hello!

To find the area of a circle you do $\pi r^{2}$

Where r stands for radius.

The radius is just half the diameter

So you put that into a calculator and get 113.1 $in^{2}$

Hope this helps!

Answer:

Explained below.

Step-by-step explanation:

The complete question is:

Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior. He records how long they slept (in hours), how many bananas they ate, gender, age (in years), and the specific breed of monkey.

(a) What are the individuals in this data set?

(b) Identify the variables that were recorded, and indicate whether each one is categorical or quantitative?

Solution:

(a)

The term "individuals", in statistics, implies or denotes the objects or people included in a statistical study.

In this case it is provided that Mr. Molesky observes a group of monkeys for 24 hours to learn about their behavior.

So, the "individuals" in this data set are the monkeys.

(b)

Categorical variables belong to a certain category or label values. Such as gender of a person, state from which a person is from, color of the marble and so on.

Quantitative variables are those variables that assume numerical values and represent some sort of measurement. Such as height, weight, annual income of the people working at the same place and so on.

In this case the variables are:

Number of bananas the monkeys ate - Quantitative variable

Gender - Categorical variable

Age (in years) - Quantitative variable

Specific breed of monkey - Categorical variable

Write 8/4 as a mixed number. how did you come to your answer

Sergeeva-Olga [200]

To write in the mixed fraction you have to simply divide 8 and 4.
To right in the mixed number we need to know numerator, denominator and divisor.
So in your problem our divisor is 4,
so now lets divide it
$\frac{8}{4}$
$= \frac{2}{1}$

So, now we have to write it as mixed number..
mixed number will be
$2 \frac{0}{8}$

Hope this helped you.. :)
