Mohamed surveyed his class on their favorite candy bar. 8 picked Snickers. 6 picked Kit Kats. 6 picked Milky Ways. If he applied the results of his survey to the whole school of 1500 people, about how many students would choose Snickers?

600 students

Step-by-step explanation:

there were 20 students surveyed because 6 + 6 + 8 = 20 there were 8/20 who picked snickers then you have to find the proportions 20 * 75 = 1500 you then multiply 8 * 75 which equals 600 so in the end out of 1500 students 600 will pick snickers

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.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
