Answer : C) 5.33 Inches

The table shows the precipitation in December, in inches, for Washington state from 2005 to 2013.

We are given with 9 values.

number of values =9

To find the mean amount of precipitation during this time we add all the precipitation then divide by number of values

Mean amount of precipitation = \frac{Sum of precipitation}{number of values}

Mean amount of precipitation = \frac{5.98+6.05+7.59 +5.27+ 3.11+7.18+ 2.95 + 7.22+2.61}{9}

= \frac{47.98}{9} = 5.32888

The mean amount of precipitation = 5.33 inches

Lilian says that 25% of a number will always be less than 75% of any other number. Complete one inequality to support Lillian's
rjkz [21]
She is incorrect cause if we take the number 20 and take 25% of it it equals 5 so now 20 is only 15. They if we take 75% away from 20 is equals 15 so then we only have 5 from 20 left. Therefore she’s incorrect because 75% leaves 5/20 and 25% leaves 15/20. Hope that makes sense.

Chose the graph that represents the equation y=|x-4|
evablogger [386]
You have not shared the graphs from which you have to choose your answer.

Why not graph y=|x-4| yourself, to help you choose the correct answer?

First, graph y=|x|.  It looks like a "v" opening up, with the vertex at (0,0).
Next, move the whole "v" graph 4 units to the right.  

Compare your result to the given answer choices.
