Answer: cumulative frequency
Step-by-step explanation:
- A frequency is the number of times a data value occurs.
- A relative frequency is the fraction or proportion of times an answer occurs.
- The cumulative frequency analysis is the analysis of the frequency of occurrence of values of a phenomenon less than a reference value.
In a data set, the cumulative frequency for a value x is the total number of scores that are less than or equal to x.
Hence, cumulative frequency represents the number of times all outcomes less than a given outcome occur.
X+3=4 the only answer is x=1 , you write out x+3=4, then you subtract 3 from each side you get x=1
Answer:
In mathematics, a coefficient is a factor linked to a monomium. Given a monomium divider, the coefficient is the ratio of the monomium by the divider. Thus the monomium is the product of the coefficient and the divider. The different coefficients will depend on the factorization of the monomium. This is usually next to the letter that accompanies the algebraic fraction. A numeric coefficient is a constant factor of a specific object. For example, in the expression 9x2, the coefficient of x2 is 9. In elemental algebra, numeric coefficients of similar terms are grouped together to simplify algebraic expressions.

Answer:
<em>Money in her purse is Rs. 500.</em>
<em></em>
Step-by-step explanation:
Let the money in her purse = Rs. 
Let the money in her Money box = Rs. 
As per question statement,
- Double the money in her purse (i.e.
) and add it to the amount in money box, she gets Rs. 1700.
........ (1)
- Triple the money in her purse (i.e.
) and add it to amount in money box (), she gets Rs. 2200.
....... (2)
<u>To find: </u>Money in her purse = ? i.e. 
Let us solve for 
using the two linear equations.
We can use substitution method here i.e. find value of one variable from one equation and then substitute that value in other equation.
Using equation (1), we get the value of as follows:
Now, let us put this value of y in equation (2) to find the value of :
<em>Money in her purse is Rs. 500.</em>
