Answer:

And using this formula we have this:

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917
Step-by-step explanation:
Let X the random variable of interest that a woman must wait for a cab"the amount of time in minutes " and we know that the distribution for this random variable is given by:

And we want to find the following probability:

And for this case we can use the cumulative distribution function given by:

And using this formula we have this:

Then we can conclude that the probability that that a person waits fewer than 11 minutes is approximately 0.917

Answer: 40 balloons
Step-by-step explanation:
x=number of balloons
2*4=8
x=(64-50-8)/0.15
x=6/0.15
x=40
Cut 5/12 of his lenght
remain 7/12 of his lenght
7/12*L - 6/7 *7/12*L=2 1/2 m
7/12*L(1-6/7)=7/12*L(7/7-6/7)=7/12*L*1/7=L/12 =2 1/2
⇒L=2 1/2 m *12=5/2*12=30 m
Original length was 30 m
