In a recent poll 60% of the middle school preferred pizza for lunch on Friday 27% prefer tacos and 13% preferred hotdogs the middle school have 860 students for Friday lunches how many prefer pizza

516 students preferred pizza

Step-by-step explanation:

To solve this problem we have to calculate 60% of the total students (860)

To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60

860 %60 = 860 / 100 * 60

860 / 100 * 60 =

8.6 * 60 = 516

60% of 860 is 516

this means that for Friday lunches 516 students preferred pizza

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.
