Answer:
0.314 = 31.4% probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:

In which
is the decay parameter.
The probability that x is lower or equal to a is given by:

Which has the following solution:

The probability of finding a value higher than x is:

In this question:

What is the probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours?

In which


So

0.314 = 31.4% probability that a randomly selected person in this city will have a commute time between 0.4 and 1 hours
Answer:
I got the answer of 21.99115. Do I need to round too? If so, look up a rounding calculator and you can put in that decimal number and round to what the question says to round to.
I hope this helps!
Answer:
Your final equation would be 192 ÷32 to get 6 as your height
Step-by-step explanation:
v=l×w×h
So if the area is 32 you could do 4×8 to get your area of 32. Take 192 and divide it by 32 to get the height.
Answer:
-3
Step-by-step explanation:
go DOWN 3 and side 1 so -3/1 or -3
Answer:
s / ( 2 pi * h) = r
Step-by-step explanation:
s = 2 * pi * r * h
Divide each side by 2 * pi * h
s / 2 pi h= 2 * pi * r * h/ ( 2 pi h)
s / ( 2 pi * h) = r
