There were 425 tickets sold for the annual everglades middle school talent show. if this is 85% of the tickets available, how many tickets went unsold? a. 15. b. 75. c. 55. d. 35.

425/85*100 = 500 thus: 500-425 =75 Tickets.

Step-by-step explanation:

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.
