The first step in this equation is to Subtract 18 from both sides of the equation.
Answer:
x ≤ 7.5
Step-by-step explanation:
First, get x alone by multiplying both sides by 3 (to get rid of the fraction)
3 (1/3x) ≥ 3(2.5)
x ≤ 7.5
(The sign will flip whenever you multiply or divide in an inequality)
Since the sign is 'less than or <u>equal to</u>' you need a closed dot on 7.5, and it will be a ray pointing left, because x will be a number smaller (aka less than) than 7.5
#1: The whole value of data is 21.
There are 21 data values on the dot plot.
#2: The number of data values is 14.
#3: The unit is: 21 ÷ 14.
And it is 1.5.
#4: A statistical question can be answered by collecting data and where there will be variability in that data.
For example, how many students enjoy playing game?
Answer:
Four more than three times a number is greater than twenty-two.What is the number?
The number is greater than 6.
Step-by-step explanation:
Given:
Four more than three times a number is twenty-two.
Let the number be 'x'.
Three times of 'x' = '3x'
Four more means further four is added.
So,
The number is 
According to the question.
⇒ 
⇒ 
...Subtracting 4 on both sides
⇒ 
⇒ 
...Dividing 6 on both sides
Now if it says that it is greater than 22 then we will use 
sign.
So the number is greater than 6 'x' > 6.
