Select ALL the correct answers. Select the scenarios that correctly represent the given graph. The radioactivity of a substance decreases by 10% every year. The amount of money in an account decreases for a few months and then increases. The sale of a product increases at first and then decreases. The height of a stone shot by a catapult reaches a maximum height and then falls on the ground. The speed of a car increases constantly by 10 miles per hour.

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.

step-by-step explanation:

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
