How can you use mean, median, range, and mode in real life and in a classroom? (explain)

To use it in a real life situation in the classroom, take all the students and line them up by their height.   If you have 5 students for example

58",60",61",62",62",  

add them together and divide by 5 to get the mean (average)

so 303 divided by 5 = 60.6  That is the mean

median is the number exactly in the middle of the list from lowest to highest

median = 61"

mode is the number that occurs the most often

So mode= 62"

Range is the difference between the highest and lowest number

range = 4"

both equations and proportions are better.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
