Such relationship with regards to the change in the value of a variable when the values of the related variables change, is termed as variation. This can be explained by an example of simple equation
y = mx
where m is a constant. If we assume that the value of m as 5 then the equation becomes as y = 5x.
What is equation of variation example?
For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is
y = 3x
.
How do you write a variation equation?
The formula
y=kxn y = k x n
is used for direct variation. The value k is a nonzero constant greater than zero and is called the constant of variation.
What is variation with example?
The individual members of a species also have differences in characteristics. For example,
humans have different coloured eyes
, and dogs have different length tails. This means that no two members of a species are identical. The differences between the individuals in a species is called variation.
What is the direct variation equation?
The general form of a direct variation formula is
y = k x y=kx y=kx
, where x and y are variables (numbers that change) and k is a constant (a number that stays the same).
What are the 4 types of variation?
Examples of types of variation include
direct, inverse, joint, and combined variation
.
What is the formula for joint variation?
Equation for a joint variation is
X = KYZ where K is constant
. One variable quantity is said to vary jointly as a number of other variable quantities, when it varies directly as their product.
What are types of variation?
- Continuous Variations: They are also called fluctuating variations because they fluctuate on either side (both plus and minus) of a mean or average for the species. …
- Discontinuous Variations:
What is joint variation examples?
When a variable is dependent on the product or quotient of two or more variables, this is called joint variation. For example,
the cost of busing students for each school trip varies with the number of students attending and the distance from the school
.
What are the 3 types of variation?
For a given population, there are three sources of variation:
mutation, recombination, and immigration of genes
.
What is the law of variation?
The Law of Variation is defined as
the difference between an ideal and an actual situation
. Variation or variability is most often encountered as a change in data, expected outcomes, or slight changes in production quality. Variation usually occurs in four separate areas: Special causes. Common causes.
Which of the following is an example of variation?
Answer: examples of genetic variation include
eye colour
,blood type ,camouflage in animals and leaf modification in plants.
Which of the following is a direct variation?
Some examples of direct variation problems in real life:
The number of hours you work and the amount of your paycheck
. The amount of weight on a spring and the distance the spring will stretch. The speed of a car and the distance traveled in a certain amount of time.
What is a good definition of variation?
Variation, in biology,
any difference between cells, individual organisms, or groups of organisms of any species caused
either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).
