In the given equation, as the value of <em>y</em> increase, the value of <em>x</em> also
increases.
- Yes, 4·y = 16·x is a direct variation
Reasons:
A direct variation is a relationship that exists between two variables. It is
also known as a direct proportion which can be expressed as; y = k·x
Where <em>k</em> is a number
The given equation is 4·y = 16·x
Dividing both sides by 4 gives;
![\displaystyle \frac{4 \cdot y}{4} = \frac{16 \cdot x}{4} = \frac{4 \times 4 \cdot x}{4}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B4%20%5Ccdot%20y%7D%7B4%7D%20%20%3D%20%5Cfrac%7B16%20%5Ccdot%20x%7D%7B4%7D%20%3D%20%5Cfrac%7B4%20%5Ctimes%204%20%5Ccdot%20x%7D%7B4%7D)
Which gives;
y = 4·x
Comparing the above equation with the equation for a direct variation gives;
y = 4·x
y = k·x
Therefore;
k = 4
The equation, y = 4·x, and therefore, the equation from which it is derived, 4·y = 16·x, is a direct variation.

Câu trả lời:
0,7
Giải thích từng bước:
Xác suất để một sự kiện xảy ra = 0,3
Cho sự kiện = A
P (A) = 0,3
Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;
P (A ') = 1 - P (A)
Vì thế,
P (A ') = 1 - 0,3 = 0,7
Answer:
min = a_1
for i:= 2 to n:
if
< min then min = ![a_i](https://tex.z-dn.net/?f=a_i)
return min
Step-by-step explanation:
We call the algorithm "minimum" and a list of natural numbers ![a_1, a_2, \cdot\cdot\cdot, a_n.](https://tex.z-dn.net/?f=a_1%2C%20a_2%2C%20%5Ccdot%5Ccdot%5Ccdot%2C%20a_n.)
So lets first set the minimum to ![a_1](https://tex.z-dn.net/?f=a_1)
min = a_1
now we want to check all the other numbers.
We can use a simple for loop, to find the minimum
min = a_1
for i:= 2 to n:
if
< min then min = ![a_i](https://tex.z-dn.net/?f=a_i)
return min
