A submarine is searching for underwater features. It is accompanied by a small aircraft and an underwater robotic vehicle. At one time the aircraft is 200 m above the surface, the submarine is 55 m below the surface, and the underwater robotic vehicle is 227 m below the surface. (Draw a vertical number line with 0 in the middle and label it “sea level”. Now draw where each of the vehicles would be located) What is the difference in height (how far apart) between the submarine and the aircraft?

What is the distance (how far apart) between the underwater robotic vehicle and the submarine?

WILL MARK BRAINILIST PLEASE ITS ONLY 2 QUESTIONS

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.

answer: it's d

step-by-step explanation:

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
