Question asked:
What is the probability that the lecture continues for at least 90 seconds beyond the end of the hour?
Answer:
90 seconds = 1.5 minutes
,
between limits 1.5 to 2
Applying limits, we get:
So,
Answer is:
0.5781

1. A college professor never finishes his lectures before the end of the hour but always finishes his lectures within 5 minutes after the hour. Let X = the amount of over-time the professor lectures for, with pdf (probability density function) kx2 0 < x < 5 otherwise a. Find the value of k and draw the corresponding density curve between 0 and 5. (Remember that the total area under the graph of f(x) is 1.) b. Which of the...
Suppose a professor never finishes his lecture before the end of the hour but always finishes within 4 minutes after the end of the hour. Let X - (elapsed time between end of hour and end of lecture) have the following probability density function: f(x) = kx for (0 SXS 4) with f(x) = 0 otherwise. a.) Determine the value of k.

"Time headway" in traffic flow is the elapsed time between the time that one car finishes passing a fixed point and the instant that the next car begins to pass that point. Let X = the time headway for two randomly chosen consecutive cars on a freeway during a period of heavy flow (sec). Suppose that in a particular traffic environment, the distribution of time headway has the following form. k. X > 1 f(x) = 6 10 X51 (a)...

The arc length of a space curve depends on the parameterization. d. The curvature of a circle is the same as its radius. e. The normal component of acceleration is a function of both speed and curvature. 2. Projectile Motion: A projectile is launched with an initial...
Page 1 Question 1 Suppose we take repeated random samples of size 20 from a population with a Select all that apply. mean of 60 and a standard deviation of 8. Which of the following statements is 10 points true about the sampling distribution of the sample mean (x)? Check all that apply. A. The distribution is normal regardless of the shape of the population distribution, because the sample size is large enough. B. The distribution will be normal as...
