A restaurant manager recorded the drinks ordered by 150 customers. Each customer ordered one drink. The results are shown in the circle graph below. How many customers ordered juice, tea or water?

82% of people ordered juice, tea, and water

Step-by-step explanation:

123 customers

Step-by-step explanation:

12%tea+30%juice+(100-12-30-18=40) 40% water=

82%

82% of 150

150*0.82

123

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.
