One pitcher contains 12 glasses of lemonade . And she serves 4 glasses of lemonade .
It is given that remaining number of glasses of lemonade = g
And we need to write an solve an equation , which gives the value of g.
And g equals to the difference of total lemonade and served lemonade, that is
So she can serve 8 more glasses of lemonade .
-4(3x + 6) is not equivalent to other expressions
<em><u>Solution:</u></em>
Let us use the distributive property to get the equivalent expression
<em><u>Distributive property is represented as:</u></em>
a(b + c) = ab + ac
<h3><u>First expression:</u></h3>Using distributive property,
Solve the expression using distributive property
Thus fourth expression is not equivalent to other expressions
Simple random selection involves a selection where all the elements in the dataset have the same chance of being selected.
The selected names are:
<em>Engler, Motola, Redmond and Zenkel</em>
We have:
--- All names
---- Sample to select
There are several ways to select a sample of 4 using a simple random sample. Some ways are:
<em />
Going by the third method, the selected positions are:
4, 8, 12, 16, 20, 24, 28 and 32
Select 4 positions that can be divided by 8
8, 16, 24 and 32
So, the selected names are:
<em>Engler, Motola, Redmond and Zenkel</em>
