Answer:
55135 lbs (rounded to the nearest pound)
Step-by-step explanation:
diameter of tank = 15 ft
Radius = 15/2 =7.5
volume of hemisphere = 2/3 ×π× 7.5³=883.5729
total weight of water = 62.4 × 883.57 = 55134.768
55134.768 rounded to the nearest pound is 55135 lb

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:
1) undefined
2) 0
Step-by-step explanation:
Slope formula:
Problem 1:
(x1, y1) = (-7, 8)
(x2, y2) = (-7, -6)
Plug those 2 points into the slope formula and solve:
Here, you can't divide by 0, so this slope is undefined. An undefined slope would make a completely vertical line on a graph. In this case, the equation of the line would be just:
Problem 2:
(x1, y1) = (-9, -8)
(x2, y2) = (3, -8)
The slope is 0, and that would make a horizontal line on a graph. The equation would be:
You don't actually need to fully work out the slope that way. If you ever have 2 points with the same x-coordinate, the slope has to be undefined. If you ever have 2 points with the same y-coordinate, then the slope has to be 0, assuming it's linear of course. You can see that in the points given, the first 2 have the same x and the second 2 have the same y.
4x+3=3(x+3)
4x+3=3x+9
4x-3x=9-3
x=6

Answer: 36.4
Explanation:
First, you have to find how much she walked in one day(15.6/3)
which is 5.2. Then, multiply 5.2 by 7 and you get 36.4.
