So this means W(-3x) = 3x. So it's equal to 3(-3x), which simplifies to be -9x. Whenever you have a function, it looks like f(x). f doesn't have to be the letter, it can be a, b, c, or like in this case, W. It just means the output of what W(x) is if x equals the number in the parentheses, which is -3x in this case.

Katena32 [7]

Answer:

b. Because the probability of being 15 or more correct is 0.0207, it is likely that she is just guessing at the questions.

Step-by-step explanation:

-This is a binomial probability distribution with p=0.5, n=20 and x=15.

The function is expressed as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}

We calculate the probability of guessing 15 or more correctly:

P(X\geq 15)=1-P(X

The probability of passing, guessing 15+ correctly, is 0.0207. This probability is very low and it is  it is likely that she is just guessing at the questions
