the angle 4pi/5 in quadrent 2
12 if not just look it up on quiz lit and you’ll get it it’s on safari or use scan and solve
Answer:
5
Step-by-step explanation:
Rental = $40
Catering = $12 per person
Budget = $100
Amount left after paying for the rental
= 100 - 40
= $60
Maximum number of guests
= 60 ÷ 12
= 5
Answer:
a)
For any integer k between 0 and 15, and 0 for other values of k.
b)
c) P(6 ≤ X ≤ 10) = 0.2737
d) μ = 15*0.75 = 11.25. σ² = 11.25*0.25 = 2.8125
Step-by-step explanation:
X is a binomial random variable with parameters n = 15, p = 0.75. Therefore
a)
For any integer k between 0 and 15, and 0 for other values of k.
b)
P(X>10) = P(X=11) + P(X=12)+ P(X=13)+P(X=14)+P(x=15)
Thus,
c) P(6 ≤ X ≤ 10) = P(X = 6) + P(X = 7) + P(X = 8) + P(X=9) + P(X=10)
Thereofre,
d) μ = n*p = 15*0.75 = 11.25
σ² = np(1-p) = 11.25*0.25 = 2.8125
Answer:
B
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 2, 4 ]
f(b) = f(4) = 16 ← from graph
f(a) = f(2) = 4 ← from graph
average rate of change = = = 6
