Consider the following sets of sample data: A: $29,900, $29,200, $26,100, $39,300, $24,200, $37,300, $34,300, $29,700, $35,100, $21,100, $38,800, $25,100, $27,200, $29,100

B: 3.42, 3.53, 4.41, 3.95, 3.18, 4.85, 3.13, 4.23,3.53, 4.72, 3.24

Step 1 of 2: For each of the above sets of sample data, calculate the coefficient of variation, CV. Round to one decimal place.

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
