Answer: 0.00067 minutes
Step-by-step explanation: if the proportion of customers who wait more than 15 minutes is 0.01, then the time interval between each waiting customer 15/0.01 = 1500 minutes.
The distribution that defines this question is that of an exponential.
An exponential distribution is dependent on the fixed time rate at which the event is occurring (λ)
For this question of ours, λ = 1500 minutes.
The mean of an exponential distribution is given as
u = 1/ λ = 1/1500 = 0.00067 minutes.
Answer:
2
Step-by-step explanation:
parallel lines have same slope.
y = 2x + 5
y = mx + b
m is the slope
b is y-intercept
Answer:
GH = 22.5
Step-by-step explanation:
Since ∆ABC is similar to ∆FGH, therefore:
Plug in the values
AC = 12 cm
FH = 18 cm
BC = 15 cm
GH = ??
Plug in the values
.
Cross multiply
12*GH = 270
Divide both sides by 12
GH = 22.5

Answer:
9:29 PM
Step-by-step explanation:
Let us add the number of minutes the first act, interval and second act lasted:
46 + 20 + 53 = 119 minutes
Converting this to hours and minutes:
60 minutes = 1 hour
119 minutes = 1 hour 59 minutes
Therefore, the time that the second act ends is:
H M
7 : 30 PM
+ <u> 1 : 59</u>
<u> 9 : 29 </u>
<u />
The second act will end by 9:29 PM
