Explanation Given Information: The provided equation is 2 x − 5 − 1 = x − 3 . Formula used: Principle of squaring states that if two numbers, a and b are equal, then their squares are also equal, that is if a = b then a 2 = b 2 also true. To solve the square root radical equation, follow the below steps: Step1: Isolate one of the radical terms from the given equation on one side of the equation. Step2: Apply the principle of squaring. Step3: Perform the step 1 and 2 again if there remains a radical expression in the equation. Step4: Simplify the equation. Step5: Verify all the obtained solutions. To apply the principal of squaring, use the given formula: ( a − b ) 2 = a 2 − 2 a b + b 2 Principle of zeroes states that if the product of two or more expressions is 0 then either one or two or all of them are 0 , that is ( x − a ) ⋅ ( x − b ) = 0 Then, either ( x − a ) = 0 or, ( x − b ) = 0 Calculation: Consider the equation, 2 x − 5 − 1 = x − 3 Since, the radical term x − 3 is already present at one side of the equation Apply the principle of squaring and use the formula ( a − b ) 2 = a 2 − 2 a b + b 2 , ( 2 x − 5 − 1 ) 2 = x − 3 2 x − 5 − 2 2 x − 5 + 1 = x − 3 2 x − 4 − 2 2 x − 5 = x − 3 Subtract 2 x from both sides of the equation, 2 x − 4 − 2 2 x − 5 − 2 x = x − 3 − 2 x − 4 − 2 2 x − 5 = − x − 3 Add 4 to both the sides of the equation to isolate the radical, − 4 − 2 2 x − 5 + 4 = − x − 3 + 4 − 2 2 x − 5 = − x + 1 2 2 x − 5 = 1 − x Now, the radical term 2 2 x − 5 is at one side of the equation

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.

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?

Answer questions 7.3.10 and 7.3.12 respectively 7.3.12. Suppose that two independent random samples (of size n1 and n2) from two normal distributions are available. Explain how you would estimate the standard error of the difference in sample means X1 − X2 with the bootstrap method.
