A student is attempting to solve the equation below for the variable x. Which of the statements below best applies to the mathematical work shown? Given \sqrt(2x+22)=5 I square both sides, which gives me the equation 2x + 22 = 25. I can then solve for x, yielding x = –9.5 as my final answer. A. The student did not correctly square both sides of the equation. B. The student did not properly isolate the variable after squaring both sides of the equation. C. The student omitted a negative solution to the equation. D. The mathematical work is correct.

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.
