Rudolph and his 4 friends threw a party and evenly shared the cost. They spent $515 on food and $250 to rent the hall. The DJ played for 4 hours and charged them $175 per hour. How much did each friend contribute? SHOW YOUR WORK BELOW *

366.

Step-by-step explanation: $515 and $250 is $765. $175 times 4 hours of playing is $700. $700 Plus $765 is $1465. $1465 divided by 4 equals $366.25 from each friend.

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.

okay..i will pick 8!
