Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.
Answer:
x = variable (a symbol, usually a letter, representing possible inputs)
4 = constant (numbers that stand alone and have a fixed value)
3 = coefficient (number multiplied by variable)
try 5.5 or 5 1/2 I hope this helps!
