Answer:
(S, FS, FFS, FFF)
Step-by-step explanation:
According to the Question,
- Given, A person must enter a 4 digit code to gain access to his cell phone. He will enter codes until he is successful.
- however, he cannot try more than 3 times or the phone will lock him out.
- Let, S denote a successful attempt and F denote a failed attempt.
So, the sample space for this random experiment is
{S, FS, FFS, FFF}
The person stops trying when he successfully enters the code or when he has failed at all 3 attempts .
Answer: First we evaluate g(0), then plug the value into f(x).
g(0) = -2(0) + 7 = 7.
Thus, we need to do f(7).
f(7) = 3(7)-4 = 21 - 4 = 17.
Step-by-step explanation: Hope it helped :)
Answer:
± 2
Step-by-step explanation:
let the number be n , then
n² - 4 = 0 ( add 4 to both sides )
n² = 4 ( take square root of both sides )
n = ± = ± 2
The number is - 2 or 2
Answer:
C) 15
Step-by-step explanation:
This is an isosceles triangle (two of the three angles are equal) so two of the sides are also equal. x is the same length as 15.
