Ben plans to sign up for a language class that will cost at least $195. his father gives him $75 and he earns $28 from mowing the lawn for his neighbors. which inequality represents how much more money he needs to save before taking the class?
x + 75 + 28 ≤ 195
x + 75 + 28 ≥ 195
x - 195 ≤ 75
x - 75 - 28 ≥ 195

Ben would want to make at least $195, so you would want to use the inequality that allows him to have $195 and over. This means that you have two choices:

x+75+28 ≥ 195

x-75-28 ≥ 195

The answer should be x+75+28 ≥ 195, because it's the sum of the money that Ben has received, plus the amount that he still needs in order to have at least $195.

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.
