Graph the function. f(x) = 3 sin (x)
Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.

Step-by-step explanation:

Mean line: y = -3

Period: 2pi ÷ ½ = 4pi

Amplitude = 5

Use the following points to sketch:

(0, -3)

(3.14, 2)

(6.28, -3)

(9.42, -8)

(12.56, -3)

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.
