The sets of data below show the heights, in inches, of students in two different preschool classes.

A box plot titled Class 1. The number line goes from 38 to 49. The whiskers range from 39 to 48, and the box ranges from 40 to 43. A line divides the box at 41.
Class 1

A box plot titled Class 2. The number line goes from 38 to 49. The whiskers range from 38 to 49, and the box ranges from 39 to 42. A line divides the box at 41.
Class 2

The teachers of the two classes want to compare the heights of their students. Which statements about the data sets are accurate? Select three options.
Because the sets are symmetrical, the mean should be used to compare the data sets.
Because the sets do not contain outliers, the MAD should be used to compare the data sets.
Because the sets are not symmetrical, the IQR should be used to compare the data sets.
Because the sets contain outliers, the median should be used to compare the data sets.
The mean and mode cannot be accurately determined based on the type of data display.

the answer is the last three

Step-by-step explanation:

When they're not symmetric, or have outliers, you have to use IQR and the median.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
