The error is that -2 times -5 is 10 not -10. Then carry on from there because that error meant the rest is wrong as well.
Answer:
True
Step-by-step explanation:
We know Billy is paid $32 for 8 hours of work.
All we have to do is divide 32 by 8 to see if whether he gets paid 4 dollars an hour,
32/8
==> 4
This is true
Answer:
Step-by-step explanation:
a) It is a binomial distribution.
n = 25
p = 0.15
b) mean = np = 25 * 0.15 = 3.75
variance = np(1 - p)
= 25 * 0.15 * (1 - 0.15)
= 3.1875
c) P(X = x) = nCx * px * (1 - p)n - x
P(X < 4) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)
= 25C0 * (0.15)^0 * (0.85)^25 + 25C1 * (0.15)^1 * (0.85)^24 + 25C2 * (0.15)^2 * (0.85)^23 + 25C3 * (0.15)^3 * (0.85)^22 = 0.4711
d) P(X = 3) = 25C3 * (0.15)^3 * (0.85)^22 = 0.2174

Answer:.8
