Answer:
D; is the right answer hope it helps ;)
Step-by-step explanation:
Answer:
f(x) =g(x) only when x = 0, or x = 1, when x = 3, they are not equal.
Step-by-step explanation:
They aren't equal because:
f(3) = 2(3) + 1
6 + 1 = 7
g(3) = 2(3)2 + 1
2x9 + 1
18 + 1 = 19
they are not equal at 3.
hope this helps
Answer:
2996
Step-by-step explanation:
5x + 4x = 6741
9x = 6741
x = 6741/9
x = 749
to get the no votes,
4x i.e 4*749
=> 4*749 = 2996
hope this helps :)

Answer:
a) 33.33%)
b) 135 minutes
c) 8.66 min
d) 50%
Step-by-step explanation:
a) the probability for a uniform distribution is
P(b<X<a) = (a-b)/(c-d) , where c and d are the maximum and minimum values
therefore the probability that the flight is more than 140 minutes ( and less than 150 since it is the maximum value)
P(140<X<150) = (a-b)/(c-d) = (150-140)/(150-120) = 10/30 = 1/3 (33.33%)
b) the mean (expected value) for a uniform probability distribution is
E(X) = (c+d)/2 = (120+150)/2 = 135 minutes
c) the standard deviation for a uniform probability distribution is
σ²(X)= (c-d)²/12 = (150-120)²/12 = 75 min²
σ = √75 min² = 8.66 min
b) following the same procedure as in a)
P(120<X<135) = (a-b)/(c-d) = (135-120)/(150-120) = 15/30 = 1/2 (50%)
