Answer:
E
Step-by-step explanation:
For all random samples of 100 garden C seedlings and 100 garden H seedlings, the average distance of all possible differences between sample proportions pˆC−pˆH from the mean of the sampling distribution is approximately 0.051.
Answer:
x < -6
Step-by-step explanation:
-2x - 4 > 8
-2x > 12
x < -6, you have to flip the inequality when you multiply or divide by a negative
Question:
The majority of U.S. car owners still buy American cars." Ideally, what would the sample be in the study that generated this stat?
answer choices
a) Everyone in the United States who owns a car
b) Everyone in the United States who owns an American car
c) A randomly selected group of car owners in the U.S.
d) A randomly selected group of Americans who own American cars
Answer:
A randomly selected group of car owners in the U.S.
Step-by-step explanation:
In this study, we are told the majority of U.S car owners still buy American cars. The sample in the study that generated this stat would be "a randomly selected group of car owners in the U.S".
⬤ Option A is incorrect, because collecting a sample from every car owner in U.S is impossible as the sample size would be rather tool large.
⬤ Option B is also incorrect because just like in option A, the sample size would be too large. Also this does not take into consideration those who don't use American cars
⬤ Option D is incorrect, this study deals with all car owners in the U.S, not Americans who own American cars. Therefore selecting a sample from Americans who own American cars would be wrong.
The quadratic function when graphed out should look like either a 'U' or an 'n' (parabola). Quadratic functions have formulas which are typically in the form of: A(x^2)+Bx+C where A, B, C are numbers and if you plot them then as mentioned before you should get a parabola.
