Here is a table of values for y = f(x).
x 0 5 10 15 20 25 30 35 40
ax) 5 6 7 8 9 10 11 12 13
mark the statements that are true.
a. f(5)=6
b. f(15)=8
c. the range for f(x) is all real numbers
d. the domain for f(x) is the set (5 6 7 8 10 11 12 13)

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.

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
