Independent or Dependent?
You flip a coin twice.
Independent
200
Move the function up to the left 2 units.
f(x) = x2
g(x) = (x+2)2
200
True or False?
Using the slope intercept formula:
y=mx+b
m is the y-intercept and b is the slope.
FALSE.
200
True or False?
The Empirical Rule and the 68-95-99.7 Rule are the same rule.
TRUE
200
True or False?
Sample size is the number of people that are in the population.
FALSE
400
Are events A and B independent or Dependent?
Independent
400
Describe the transformation
TO
Up 8 Units
400
Is the point (2,1) a solution?
YES
400
What desmos function finds the probability or area under the curve given z-score(s).
Hint: think min:____ and max:_____
normaldist(mean,sd)
400
What is the definition of population?
The entire group that you want to draw inferences/conclusions about. This is the set you will pull a sample from.
600
Are events A and B independent or Dependent?
Dependent
600
Describe the transformation
TO
Reflected over the x-axis and down 3 units. OR up 3 units then reflected over x.
600
What is the solution?
(1,8)
600
What desmos function finds the z-score given a probability or area under the curve?
normaldist(mean,sd).inversecdf(.___)
600
What is the definition of sample?
(NOT sample size.)
The group you will collect data from. You will use the sample to draw conclusions about the population.
800
A basket contains 8 apples and 5 bananas. You randomly select one piece of fruit and eat it. Then you randomly pick another fruit. The first fruit is an apple the second fruit is a banana.
Is the event Independent or Dependent? What is the probability?
Dependent 10/39
800
Write the new equation when f(x) is moved right 8 units.
f(x) = log(x)
g(x) = log(x-8)
800
What region should be shaded? (the answer/feasible region)
2
800
What does μ and σ stand for?
μ =Mean and σ = standard deviation
800
What is the definition of bias?
In favor or against a person/group compared to another that could be considered unfair.
1000
A cooler contains 13 sodas: 4 Pepsi, 4 Mountain Dew, and 5 Coke. You randomly grab a bottle. Then you return it and mix up all the bottles. You select another bottle. The first time you pick a Pepsi the second is a Coke.
Is the event Independent or Dependent? What is the probability?
Independent 20/169
1000
Write the new equation when f(x) is reflected over the x-axis and moved down 10 units
f(x) = x
g(x) = -x-10
1000
What is the maximum value of the objective function?
The point (2,9) gives 74
1000
95% of the data falls between how many standard deviations from the mean?
2 (2 to the left of the mean and 2 to the right of the mean)
1000
What is a type of sampling method that is supposed to be unbias?
(Simple) Random Sampling
Systemic
