Answer:
Please read the answers below
Step-by-step explanation:
Let's use x for writing the inequalities asked:
A number is less than 2:
x < 2
A number is greater than 6 and less than or equal to 9:
6 < x ≤ 9
The first one is 2x^2+2x-2
the second one is 2x^2-2x-2
the third one is 6h+6k
<span>No, you can't make a prediction from a scatter plot that doesn't show any associations. There have to be associations in order to form a trend. If there is no trend, there is no way to make a prediction. A scatter plot is similar to a line graph where you can mark the appropriate data points in order to see if a trend is developing.</span>

Answer:
51.1 ≈ r
Step-by-step explanation:
"A bicycle wheel travels 321 in for each revolution"- means that 321 is the circumference of the wheel that is a circle.
C = 2· π· r
What is the radius of the wheel ?
321 = 2· π· r, divide both sides of the equation by 2 π
(321/2·π) = r , use calculator, solve and round the answer
51.1 ≈ r
