Linear Equations

Let's see how you are going...

Multiple Choice

Solve:
2(2x + 3) = -6(x + 9)

• 1.2
• 6
• -6
• 7.5

Linear Graphs

What do we know...

Multiple Choice

Write the equation for this graph? 

• y = - 10x + 60
• y = - 5x + 60
• y = - ¹/₂ x + 60
• y = - x + 60

Multiple Choice

If m=3 and c=6, what is the correct equation?

• y = 3 - 6
• y = 3x - 6
• y = 3x + 6
• y = 6x + 3

Statistics

What do we know...

Multiple Choice

Use the 1.5 IQR rule to determine if there are any outliers for the following numbers:

84, 88, 72, 74, 98, 35, 94

• Yes, 35 is an outlier.

• Yes, 33 is an outlier.

• Yes, 98 is an outlier.

• There are no numbers less than 39 or greater than 124, therefore there are no outliers.

How to find Outliers using 1.5 IQR rule

Step 1: IQR X 1.5

Step 2: Q1 - (IQR X 1.5)

Step 3: Q3 + (IQR X 1.5)

Any number in the data set that is below or above these numbers are outliers.

Example 5: Find Outliers

Find the outliers for the following data set.

{35,16,17,17,19,9}

What does a Box and Whisker Plot includes?

Other Names:

Lower Extreme = Least Value = Minimum

Lower Quartile = First Quartile = Q1

Median = Q2

Upper Quartile = Third Quartile = Q3

Upper Extreme = Greatest Value = Maximum

Multiple Choice

Which has a larger IQR?

• Zach
• Steven
• They have the same IQR

What is the least number of dogs that attended Doggie Day Care in a week?

Stem and Leaf Plot

is a convenint way to organize data using numerical order and place value

Indices

What do we know...

Multiple Choice

Simplify

 $\frac{2mn^3}{\left(3mn^{-2}\right)^2}$  

•  $\frac{2m^2n^5}{3}$  
  

•  $\frac{2m^2n^3}{3}$  
  

•  $\frac{2n^7}{9m}$  

•  $\frac{2mn^3}{9}$  

Multiple Choice

A population of 1500 deer decreases by 1.5% per year. At the end of 10 years, there will be approximately 1290 deer in the population.

Which function can be used to determine the number of deer, y, in this population at the end of t years?

• $y=1500(1-0.015)^t$

• $y=1500(0.015)^t$

• $y=1500(1+0.015)^t$

• $y=1500(1.5)^t$
