Giving 20 points
Can someone explain to me how to get the mean of a data set.

Im doing stem and leaf plots as well as just lines of numbers and i don't quite understand how to get the mean.

you have to add all plot points then divide by how many plots

Step-by-step explanation:

example 1 2 3 4 four points add them 1+2+3+4 10 divide that by 4 because how many there are u get 2.5

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

yes. we do proportions in probabilities.
