Can a -150/10 be classified as both a rational number and a integer
irakobra [83]
Yes! This is because -150/10 can be simplified to be -15, which is a rational number.

The word “rational” sounds like another math word you’ve heard of before. Do you know what it is?

Well, it’s “ratio”!! Ratios can be seen in the forms x:y and x/y.


ANY RATIONAL NUMBER HAS THE ABILITY TO BE WRITTEN AS A RATIO!! This will completely exclude numbers with super long decimal points (ex: 1.2345678809928374737272828...)

This number also meets the requirements of being an integer. An integer is any whole number (this excludes decimals and fractions)

I know it’s written as a fraction. However, the fraction could be simplified, making it -15, which means this is both a rational number and an integer!!

Thank you for helping me :D
Aleonysh [2.5K]
The answer is both sets of statistics give the same information:

First, find the mean: 2 • 5 = 10, 3 • 4 = 12, and 10 • 1 = 10

10 + 12 + 10 = 32

Ten dots altogether : 32 ÷ 10 = 3.2

Mean = 3.2

Second, find the median: 2, 2, 2, 2, 2, 3, 3, 3, 3, 10

2, 2, 2, 2, <em>2, 3,</em> 3, 3, 3, 10

2 + 3 = 5

5 / 2 = 2.5

Median - 2.5

What is the effect on the graph of the function f(x) = x when f(x) is replaced with −f(x) + 5?
prohojiy [21]

Answer:

The function f(x) translated left by 5 units and then it is reflected across the x-axis.

Step-by-step explanation:

The original equation of the graph of the function is f(x) = x ........ (1)

If we replace f(x) by [- f(x) + 5] then the equation becomes - f(x) + 5 = x  

⇒ f(x) = - (x - 5) ..... (2)

So, comparing equations (1) and (2), we can conclude that the graph of the function f(x) translated left by 5 units and then it is reflected across the x-axis. (Answer)
