What is the significance of the ordered pair (3, 0) to the graph?
a. its the vertex
b. it is an x-intercept
c. it is the y-intercept
d. it is the maximum point

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.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
