Some of the eggs at a market are sold in boxes of six. the number, x, of broken eggs in a box has the probability distribution given in the following table.

x 0 1 2 3 4 5 6
p(x=x) 0.8 0.14 0.03 0.02 0.01 0 0

(find the expectation and variance of the number of unbroken eggs in a box)

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.
