Suppose that you have a pattern rule with an algebraic
expression.
a) What does the constant term tell you about the pattern?
b) What does the numerical coefficient tell you about the
pattern?

The constant term tells you what is constant, or what can NOT change.

The numerical coefficient tells you the constant multiplier of the variables in a term.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
