I want to ask the percentage of frequency words in English, for example, never is 0% Ask% of commonly, often, sometimes, hardly ever, etc

Some grammarians often use percentages to express the frequency of the above time adverbs, that is: always-100%, normally-90%, often-60%, some times-30%, hardly-10%, never-0%
always 100%, usually 70% often50% sometimes 30%
What are the words of frequency in English
Frequency words like "often" often
Frequent
Always, always
Never
Seldom hardly
Usually, it's similar to often
Sometimes, occasionally
Few of them
Ever, once a day, twice a day
Every day; week, month
Always, always, often, sometimes, occasionally
If the function f (x) = 1 / √ ax ^ 2 + 4ax + 3 is defined as R, the value range of real number a is obtained
F(x)=1/√(Ax²+4Ax+3)
Because the domain of F (x) is r
So ax & # 178; + 4ax + 3 > 0
When a = 0
When a > 0, △ = (4a) &# 178; - 12a
From the meaning of the title, we can see that ax & # 178; + 4ax + 3 > 0 holds when x ∈ R
If ﹤ a ≠ 0, then ﹤ a ≠ 0
When a = 0, 3 ＞ 0 is always true. To sum up, 0 ≤ a ＜ 3 / 4
The inverse function of the function y = f (- x) defined on the real number set R is y = f ^ (- 1) (- x) (- 1 on the upper right - x on the true number)
Then y = f (x) is an odd function. Why?
Y = f ^ (- 1) (- x) gives - x = f (y)
That is, the inverse function of y = f ^ (- 1) (- x) is y = - f (x)
That is, f (- x) = - f (x)
So f (x) is an odd function
It is known that the number corresponding to point a on the number axis is 1, and the number corresponding to point B is - 2,
The little white rabbit starts from point B and moves at a speed of 3 units per second. If they start to move for 3 seconds at the same time, please answer (1) when they are farthest apart, what are the corresponding numbers of the positions of the tortoise and the little white rabbit? (2) when they are nearest, what are the corresponding numbers of the positions of the tortoise and the little white rabbit?
(1) When they are farthest apart, the number corresponding to the location of the tortoise is 4, and the number corresponding to the location of the rabbit is -- 11
(2) When they were closest, the turtle's position was 1 / 4, and the rabbit's position was 1 / 4
The rabbit starts from point B and moves at a speed of 3 units per second. If they start to move for 3 seconds at the same time, please answer (1) when they are farthest apart, what are the corresponding numbers of the positions of the tortoise and the rabbit? (2) When they are closest to each other, what are the numbers corresponding to the positions of the tortoise and the rabbit?
Moving in the same direction or in the opposite direction?

Given the function f (x) = LG (MX & sup2; - MX + 3), if the range is r, the range of M is obtained
Then the real number MX & sup2; - MX + 3 belongs to (0, positive infinity)
M = 0, not true
M is not 0. For the parabolic function MX & sup2; - MX + 3, in order to get (0, positive infinity), the opening must be upward, and there is an intersection point with the X axis, then M > 0, Δ > 0, and the solution is OK
Solve the inequality | Log1 / 3x | (where 1 / 3 is the base and X is the real number) + | Log1 / 3 (3-x) | (where 1 / 3 is the base and 3-x is the real number) ≥ 1
Solve the inequality | Log1 / 3x | + | Log1 / 3 (3-x) | ≥ 1, because some mathematical symbols cannot be typed, so please see the explanation in brackets,
Why is x (3-x) less than or equal to 1 / 3?
Because there are absolute values, it needs to be discussed
The first assumption is that both the preceding and the following terms are greater than zero, but it is not true
If the former is greater than zero and the latter is less than zero, the absolute value is removed, and it is easy to combine the two
3 assume that the first term is less than zero and the second term is greater than zero
The special case of one item being zero
Simple x is greater than 0, X is less than 3, the absolute value of X (3-x) is less than or equal to 1 / 3, and then find the intersection
The absolute value of x-3 is greater than x-3
The number corresponding to point a on the number axis is - 1. A bug starts from point a and crawls along the number axis at a speed of 5 units per second to the back of point B,
How many units of length did the bug crawl? How many units of length did the bug crawl? What is the number corresponding to point B? (it is necessary to have the process of answering questions and ensure that it is correct.)
solution
The length of the insect is 45 * 9
The number corresponding to point B is 45 / 2-1 = 21.5
Look where it's going! Climbing left is - 23.5, climbing right is 21.5
