All things Quadratic
This is the name of the graph of a quadratic function.
What is a parabola?
This type of sampling technique might survey the 1st 75 people at the mall to find out their favorite restaurant in the food court.
What is convenience?
This linear equation reflects over the y-axis, gets wider by 1/2, and rises 2 on the y-axis.
What is y=-1/2x+2?
In a normal distribution, this is value of the mean, median, and mode.
What is 0?
These type of events cannot occur at the same time?
What is mutually exclusive events?
This is the transformation from y=x^2 for y=x^2+2.
What is moved 2 units up?
This sampling technique will create strata or categories combined with a random sampling to survey the population desired.
What is stratified sampling?
This is the equation of the line that goes through the points (4,2), (-1,-3).
What is y=x-2?
Normal distribution uses these 2 measures when labelling a normal distribution curve.
What is mean and standard deviation?
This is the type of probability that we expect to occur when a die is rolled, a card is drawn, a coin is flipped, or a spinner is spun.
What is theoretical probability?
What is moved 3 units right?
This sampling technique assigns a random number to each person in the population, chooses a place to start, then chooses the nth person repeatedly until the sample size is reached.
What is systematic?
This linear trend line has x increasing and at the same time has y decreasing. Is it trending positive or negative?
What is negative?
These are 3 characteristics of a normal distribution.
What are symmetrical, bell-shaped, and mean=median=mode?
The theoretical probability of P(even) on a fair 6-sided die.
What is 1/6?
These are the transformations from y=x^2 for
y=-x^2+4.
What is reflected over the x-axis and moved up 4 units?
This sampling technique uses a random number generator to choose the sample size for the survey.
What is simple random?
This point is the solution for y=x-3 and y=2x+4.
What is (-7,-10)?
This value is calculated to standardize 2 dissimilar types of data.
What is a z-score?
Using a fair 6-sided die and a fair 2-sided coin, the theoretical probability of P(odd) and P(heads).
What is 3/12 or 1/4?
This is the ordered pair of the vertex for the quadratic function y=(x+4)^2-2.
What is (-4,-2)?
Sampling techniques create this to represent the desired population.
What is the sample size?
In a system of inequalities, all solutions will be here.
What is in the shaded area or on the solid line?
This is the z-score if the test score is 84, the mean is 87, and the standard deviation is 2.5.
What is -1.2?
This is how many ways you can order 6 names on a roster.
What is 720?
