Step-by-step explanation: 56
The answer for that question is about 3 I think is this mathswatch
Answer:
Step-by-step explanation:
The basic cost of the Snout is 45.99
15% of that amount = 45.99*15/100 = <u> 6.90</u>
Total Cost 52.89
You could figure out the total cost a slightly different way.
You could set up
Cost = snout (1 + 15%)
Cost = snout(1 + 15/100)
Cost = snout( 1 + 0.15)
Cost = 45.99(1.15)
Cost = 52.89
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%)
