In a certain population of mussels (mytilus edu- lis), 80% of the individuals are infected with an intestinal parasite.13 a marine biologist plans to examine 100 ran- domly chosen mussels from the population. find the probability that 85% or more of the sampled mussels will be infected, using the normal approximation without the continuity correction.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
