or
-4x + 8
Are all functions also relations?
Yes
What is the formula for the area of a rectangle?
A = l x W
What is the name of the theorem associated with the formula a2+b2=c2
The Pythagorean Theorem
Which sample is better for making a prediction?
Sample A) A random sample of 500 pencils from 20 machines.
Sample B) A random sample of 500 pencils from 1 machine.
Sample A, This sample gives you a much more diverse sample group because we are selecting from different Machines

b. A graph
c. An Equation
d. A Theorem
D. A Theorem.
What is the Formula for the Area of a circle?
A = (pi)r2
What is the line that is drawn on a scatter plot that shows the trend of the data?
The Line of Fit
or

Find the difference:
(4b - 3) - (7b + 6)
-3b - 9
or
-3(b + 3)
What is the formula associated with slope intercept form?
y = mx + b
What is the formula for the Surface area of a cylinder?
Surface Area = 2(pi)r2 + h(2(pi)r)
What is the product of repeated factors?

You randomly draw a lane number for a 100-meter race. Then your friend randomly draws a lane number for the same race. Are the events independent or dependent? Why?
Dependent, You're both choosing positions for the same race.
Solve the inequality.
3(x + 4) >= 12
x >= 0
You see a graph of a vertical line, is that graph a linear function? Why or why not?
Vertical lines, while being straight, fail the vertical line test and are not functions. If a graph is not a function, it cannot be a linear function.
What is the formula for the surface area of a Rectangular Prism?
The more you conduct an experiment, the closer to the Theoretical probability of the event you get. What is this term referred to as?
The Law of Large Numbers
You want to estimate the number of books students in your school read over the summer. you survey every fourth students who enters the school. Is the sample random? Why?
Yes, because you're sample size will represent the school and the way the students are selected is random.
A music teacher budgets $150 for new books. The minimum cost of a new book is $12, so she buys 12 books. Is this the minimum or maximum number of books?
The Maximum, if she were to buy one more, she would be spending at least $156.
From our practice of graphing and writing linear equations, not all linear equations represent functions, provide an example to back up this claim.
x = c, where c is a constant (this is a vertical line.)
Find the surface area of a rectangular prism with the following dimensions.
