Answer:
0.16807 ; 0.83193
Step-by-step explanation:
Given that:
Number of trials, n = 5
Probability of success, p = 0.30
P(r = 0)
Using the binomial probability relation :
P(x =r) = nCr * p^r * (1 - p)^(n - r)
(a) Find P(r = 0).
P(r = 0) = 5C0 * 0.3^0 * (0.7)^(5- 0)
= 1 * 1 * 0.16807
= 0.16807
(b) Find P(r ≥ 1) by using the complement rule
P(r ≥ 1) = 1 - P(r = 0)
P(r ≥ 1) = 1 - 0.16807
P(r ≥ 1) = 0.83193
So all you have to do here is,
Whats 5% of 4321
Witch = $216.05
Y=f+cx where f is her fixed income and c is the commission she earns per sale...
we can say, to make it just like the point slope form of the line:
y=cx+f, so we first need to find the slope...c=110-95=125-110=15 so
y=15x+f, now we can solve for her fixed income using (1,95)
95=15(1)+f
f=80 so
y=15x+80 (so C. is the answer)
