Answers

Answer 1

Answer: Mode is the number that occurs most often. Out of those numbers, 72 would be the mode. But since that's not an option, I would say 84.

Answer 2

Answer: the mode is 72 because 72 appears three times and the others are shown twice but 72 isn't an answer and the only other one with the most often is 84 which appears twice so the answer would be A

Which is greater 6km or54,000 mm

Answers

1 km = 1,000,000 millimeters
6 km = 6 * 1,000,000 millimeters = 6,000,000 mm

6,000,000 mm is greater than 54.000 mm

Therefore, 6 km is greater than 54,000 mm,

1km = 1000000mm
6km= 6000000mm
6000000mm > 54000mm
so 6km is greater than 54000mm

I am so confused on functions! Please help!

Answers

Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like f(x)= 23y-5 (that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise.

Is 0.23 a rational number ?

Answers

The given number 0.23 which is the form of decimal is a rational number. The statement is true.

The number in the form of $(p)/(q)$ , where p is numerator and q is denominator and the denominator is not equals to zero, is called as rational number.

The given number 0.23 is a rational number which can be written as $(23)/(100)$ in the fraction form, where 23 is the numerator and 100 is the denominator, which is not equal to zero. So, the number can be considered as a rational number.

Thus, 0.23 is a rational number.

Yes, $\boxed{0.23}$ is a rational number.

Further explanation:

Real numbers includes all the rational numbers (integers and fraction) and all the irrational numbers.

Rational number is any number which can be expressed in the form of $(p)/(q)$ where $p$ and $q$ are integers and $q$ is non-zero and $(p)/(q)$ should be in the simplest form.

And those real numbers which are not expressed in the form of rational number are called irrational numbers.

For example: $\pi$ , $√(2)$ , $√(5)$ .

Here, the number is $0.23$ and which is in the form of decimal.

Express the number $0.23$ in the form of fraction as follows:

$0.23=(23)/(100)$

This implies that $(23)/(100)$ is the fraction form of $0.23$ .

Therefore, the fraction $(23)/(100)$ is in the form of $(p)/(q)$ where, $p$ is $23$ and $q$ is $100$ .

Also, here $q$ which is $100$ is non-zero.

Thus, $0.23$ can be written in the form of rational number.

Hence, $0.23$ is a rational number.
