HELP! I will give BRAINLIEST!! Please EXPLAIN Olga tried to solve an equation step by step. Equation: 1/4 ( 1/3k + 9) = 6 Step 1: 1/3k + 9 = 24 Step 2: 1/3k = 15 Step 3: k = 5 Find Olga's mistake. Step 1 Step 2 Step 3 Olga did not make a mistake.

Olga's mistake was in Step 3 because she divided the entire equation by 3 instead of dividing it by 1/3.

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.

x = 25/2304
