Evaluate 7w - 14 when w =8

Show two ways to find the same value of the expression and make sure that one way uses distributive property.

The value for  7w - 14  when w =8 is 42.

Step-by-step explanation:

First method is directly substituting the value:

Equation:   7w - 14 , for w= 8,

               = 7w - 14 = 7*8 - 14 = 42.

Using distributive property :

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products.

Equation:   7w - 14

               = 7(w-2) , for w=8,

               = 7(8-2)

               =7*8 - 7*2

               =56 - 14

               =42.

binomial distribution

median= 2

range = 7-0 = 7

how to find median?

no. of term=28

median=(28+1)/2=14.5th term

the 14th and 15th term are 2, therefore the median is (2+2)/2 = 2
