Multiple 2x * 5x =10x^2
Multiple 2x * -1 = -2x
Multiple 6 * 5x = 30x
Multiple 6 * -1 = -6
Add 30x + (-2x) = -28x
10x^2 + 28x -6 is the final answer
Answer:
a) 0.1091
b) 0.9994
c) 0.5886
Step-by-step explanation:
X = the number of fish out of 20 that die after 24 hours
x = 0, 1, 2, . . . , 20
X~ Binomial (n= 20, p =0.20)
P(14 survive) = P(X = 6)
=
=0.1091
Similarly we can find out
P(at least 10 survive) = P( X <= 10 ) = (Using technology) = 0.9994
P(at most 16 will survive) = P(X <= 16) = (Using technology) = 0.5886
A represents it, since it’s on the negative side
Answer: I think 59/100
