Answer:
74.99%
Step-by-step explanation:
We have a binomial problem, where the sample sample size is 15 and p = 80%
Find the probability that exactly 12 of the 15 consumers recognize the brand name, where n = 15 and x = 12
P (x) = nCx * [(p) ^ x] * [(1 - p) ^ (n-x)]
Replacing:
P (x = 12) = 15C12 * [(0.8) ^ 12] * [(0.2) ^ (3)]
P (x = 12) = 455 * [(0.8) ^ 12] * [(0.2) ^ (3)]
P = 0.2501
To find the probability that the number recognized by the mark is not 12, it would be
P = 1 - P (x = 12)
P = 1 - 0.2501
P = 0.7499
That is, the probability is 74.99%

a) g(2) = -4
b) g(-4) = -22
=====================================
Work Shown:
For part a, we replace every x with 2 and simplify
g(x) = -x^2 + x - 2
g(x) = -(x)^2 + x - 2
g(2) = -(2)^2 + 2 - 2
g(2) = -4 + 2 - 2
g(2) = -2 - 2
g(2) = -4
--------------
Part b is the same story, but with a different input this time
g(x) = -x^2 + x - 2
g(x) = -(x)^2 + x - 2
g(-4) = -(-4)^2 + (-4) - 2
g(-4) = -16 - 4 - 2
g(-4) = -20 - 2
g(-4) = -22
