Explanation Given Information: The provided equation is N 4 − 7 = 8 . Formula used: To solve the equation and prove the solution, follow the steps as mentioned below. Step 1 : Rearrange the unknown values to the left side and known values to the right side of the equation by using the following sequence of order to solve the equation. (a) Paranthesis, if any then clear it before performing the next operations by mutiplying the coefficient with each term inside the paranthesis. (b) In order to solve the equations with more than one operation, apply opposite operations from the provided operation in the equation, that is, addition if substraction is in the equation and multiplication if division is provided in the equation and vice versa. Step 2 : Prove the solution by substituting the value obtained from step 1 in the original equation then check the left and right of the equation if, they are equal then the answer is correct. Calculation: Consider the provided equation, N 4 − 7 = 8 To arrange the known values to the right side and unknown to the left side apply the opposite operation of subtraction, add 7 to both sides, N 4 − 7 = 8

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

To the Internal Revenue Service, the reasonableness of total itemized deductions depends on the taxpayer’s adjusted gross income. Large deductions, which include charity and medical deductions, are more reasonable for taxpayers with large adjusted gross incomes. If a taxpayer claims larger than average itemized deductions for a given level of income, the chances of an IRS audit are increased. Data (in thousands of dollars) on adjusted gross income and the average or reasonable amount of itemized deductions follow.

7.2.10 Researchers in the Hopkins Forest also count the number of maple trees (genus acer) in plots throughout the forest. The following is a histogram of the number of live maples in 1002 plots sampled over the past 20 years. The average number of maples per plot was 19.86 trees with a standard deviation of 23.65 trees. a. If we took the mean of a sample of eight plots, what would be the standard error of the mean? b. Using the central limit theorem, what is the probability that the mean of the eight would be within 1 standard error of the mean? c. Why might you think that the probability that you calculated in (b) might not be very accurate? 2. A normal population has mean 100 and variance 25. How large must the random sample be if you want the standard error of the sample average to be 1.5?
