Is linear equation easy?

**Linear equations** are easy to solve .They are a type of **mathematical **equation that involve one or more variables, in which all terms are of the first degree.

The** general form** of a linear equation is Ax + B = C, where A, B and C are numerical coefficients and x is a variable. Linear equations can be solved by first rewriting the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Then, the y-intercept can be determined by substituting in a value for x and solving for y. To find the slope, two points on the line must be chosen, and the formula m = (y2 - y1)/(x2 - x1) is used to calculate the slope. Once the slope and y-intercept are known, the equation can be written in its **slope-intercept **form and solved for x.

Linear equations can also be solved using the **substitution method**, where one of the variables is substituted with a numerical value. This method can be used when the equation is already written in its standard form, Ax + B = C. By solving for x, the value of x can be found and substituted back into the equation to find the value of C.

Finally, linear equations can also be solved using the elimination method, which is used when there are two linear equations with two unknowns. The two equations are added together, and the **coefficients** of one of the variables are **eliminated**. This method is useful for solving systems of linear equations.

Which function is always discontinuous?

A function can have an **asymptote **if it approaches a horizontal or vertical line but never touches it. There are several types of functions that can have asymptotes, including rational functions, exponential functions, and logarithmic functions.

A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.

There is no function that is always **discontinuous**. A function is either continuous or discontinuous at a particular point, but it is not necessarily either one at all points.

For example, the function f(x) = x^2 is continuous at all points, but the function g(x) = |x| is discontinuous at x=0.

On the other hand, there are **functions **that are discontinuous at an infinite number of points, such as the Dirichlet function, which is defined as follows:

f(x) = { 1 if x is irrational

{ 0 if x is rational

This function is discontinuous at all rational points, but it is continuous at all irrational points

Is arithmetic mean 10 and standard deviation is 20 then coefficient of standard deviation?

The **coefficient of variation** is 200%.

The **coefficient of variation** is the** ratio** of the standard deviation to the mean. One form of measure of **dispersion** is the coefficient of variation. A number called a measure of dispersion is used to assess the** degree **of **data variability**. As a result, the coefficient of variation is used to assess how much data deviate from the mean or **average value. **The **acronym **CV stands for coefficient of variation.

Given that,

what is the solution of 10(w+3)=70

**Answer: w = 4**

**Step-by-step explanation:**

**To solve the equation 10(w+3) = 70, we will work to get w by itself:**

**1. Divide by 10. This will get us closer to w.**

**(10( w + 3))/10 = 70/10**

**w + 3 = 7**

**2. We now have the equation w + 3 = 7. All we need to do now to get w by itself (or isolate it) is to subtract 3.**

**(w + 3) - 3 = 7 - 3**

**w = 7 - 3**

**w = 4**

**3. We can check our solution by inputting our found value, w = 4, into the equation.**

**10( 4 + 3 ) = 70**

**10(7) = 70**

**70=70**

**Because both sides of the equation are true, our solution of w = 4 is correct.**

**Answer: w = 4**

**Step-by-step explanation:**

10(w+3)=70

10w + 30 = 70

Consider five-digit integers that have the following properties. Each of the digits is

1, 2 or 3, and each of 1, 2, 3 occurs at least once as a digit; also, the number is not

divisible by 2 nor divisible by 3.

What is the difference between the largest and the smallest of these integers?

O

**Answer:**

22098

**Step-by-step explanation:**

You want the **difference** between the **largest and smallest** **5-digit numbers** whose digits are **from the set {1, 2, 3} **and include each of these at least once. The numbers **cannot be divisible by 2 or 3**.

The number will be divisible by 3 when its sum of digits is a multiple of 3. Since 1, 2, and 3 are prescribed digits, the remaining two digits must not have a total of 3 or 6. The largest possible remaining digits are {2, 3}, and the smallest remaining digits are {1, 1}. (Using {3, 3} for the largest digits would give a number divisible by 3.)

The number will be divisible by 2 if the least significant digit is 2. The largest and smallest digits are not 2, so that will not be an issue.

LargestThe largest number will place the largest available digit in the place with the highest place value: 33221.

SmallestThe smallest number will place the smallest available digit in the place with the highest place value: 11123.

DifferenceThe desired difference is the difference of these numbers:

33221 -11123 = **22098 . . . . difference of largest and smallest**

The **difference **between the **two **numbers will be 1998.

A **numeral **system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set in a consistent manner using digits or other **symbols**. In different numeral systems, the same sequence of symbols can represent different numbers.

Given that Consider five-digit integers that have the following properties. Each of the digits is 1, 2 or 3, and each of 1, 2, 3 occurs at least once as a digit; also, the number is not divisible by 2 nor divisible by 3.

The largest number will be 3211.

The smallest number will be 1213.

The difference between the largest and the smallest number will be calculated as,

D = 3211 - 1213

About what percent of 212 is 400?

**Answer:**

**Step-by-step explanation:**

If you're wondering about what percent of 212 is 400, the answer is 189.3%. This means that 400 is 89.3% higher than 212. It’s easy to see that, when compared side by side, 400 is a much bigger number, almost twice as great as 212. Put another way, if you divide 400 by 212, you get 1.89—that’s your answer! Clearly, 400 is a great deal larger than 212 and this difference in size can be expressed as a percentage increase of 189.3%.

Approximately 19.05% of 212 is 400.

**Answer:**

**Step-by-step explanation:**

Solution for 212 is what percent of 400:

212:400*100 =

(212*100):400 =

21200:400 = 53

Now we have: 212 is what percent of 400 = 53

Question: 212 is what percent of 400?

Percentage solution with steps:

Step 1: We make the assumption that 400 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=400$.

Step 4: In the same vein, $x\%=212$.

Step 5: This gives us a pair of simple equations:

$100\%=400(1)$.

$x\%=212(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{400}{212}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{212}{400}$

$\Rightarrow x=53\%$

Therefore, $212$ is $53\%$ of $400$.

the answer is 53 or 188.68%

At each interval fall. Bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins (intervals) must be contiguous and often (but not necessarily) the same size.

If the bins are the same size, bars are drawn across the bins, with heights proportional to **frequencies** (number of cases in each bin).
