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.
Answer: 4,772.8 cm2
Step-by-step explanation:
Hi, to answer this question we have to calculate measures of the rectangular label:
The width of the label is equal to the height of the can (8 cm), and the length is equal to the perimeter of the top or bottom of the can.
Perimeter of a circle (circumference): 2 π radius
Replacing with the values given:
C = 2 (3.14) 5 = 31.4 cm
So, the area of one label is:
Area of a rectangle: length x width = 31.4 x 8 = 251.2 cm2
Multiplying for the number of labels (19)
251.2 x 19 = 4,772.8 cm2
Feel free to ask for more if needed or if you did not understand something.
Answer:
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.
Hope this helps you.
