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:
f=2
Step-by-step explanation:
0.3+0.5f-0.7
Move the varibale (0.5f) to the left-hand side and change it's sign to negative.
-0.5+0.3+-0.7
Move the constant to the right hand side and change it's sign
-0.5f=-0.7-0.3
Calulate the differnce
-0.5f=-1
divide both sides by -0.5
F=2
