About how many tax returns are selected by the irs for audits each year?
a) less than one percent
b) ten percent
c)twenty percent
d) twenty-five percent

Option: A is the correct answer.

A) Less than one percent.

Step-by-step explanation:

Tax returns are selected for audits in several ways.

The primary way that the IRS selects returns for audit is the Discriminate Function (DIF) system.

The DIF system uses mathematical formulas to weigh the various characteristics of tax returns and score them accordingly.

Less than one percent  of the tax returns are selected by the IRS for audits each year.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
