Hãy xác định giá và lượng cân bằng của thị trường có ba hàng hóa với các hàm cung và hàm cầu của mỗi loại hàng hóa như sau:
- Hàng hóa 1: Qs1 = 3p1, Qd1 = 120 − p1 + p2 + 2p3
- Hàng hóa 2: Qs2 = −10 + 2p2, Qd2 = 150 + p1 − 2p2 + p3
- Hàng hóa 3: Qs3 = −20 + 5p3, Qd3 = 250 + 2p1 + 2p2 − 3p3

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: just trying to get points sorry : (

alaska, florida, nevada, south dakota, texas, washington and wyoming, tenessee and new hampshire.

step-by-step explanation:

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
