What is the period of the sinusoidal function

Step-by-step explanation:

On the given graph the period is the distance between maximum points -7 and 3:

The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.

From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units

Therefore, 10 units is the right answer.

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.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
