If a coin is flipped 75 times, in how many ways could there be exactly two tails? a. Subscript 73 Baseline P Subscript 2 Baseline = 5256 b. Subscript 73 Baseline C Subscript 2 Baseline = 2628 c. Subscript 75 Baseline C Subscript 2 Baseline = 2775 d. Subscript 75 Baseline P Subscript 2 Baseline = 5550

answer: plz give a pic and answer choices so i can answer!

step-by-step explanation:

80 the answer is 80

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
