The second hand in a clock is spun and the outcome α is the second where the hand comes to rest. Let Zbe the minute where the hand comes to rest. Find the pmf of Z. Find the conditional pmf of Z givenA= {first 20 minutes}; given B= {2 ≤ α ≤ 200}
In Problem, let A = {hand rests in last 10 minutes} and B = {hand rests in last 5 minutes}. Find P[B|A] for parts a, b, and c.ProblemConsider Problem where the minute hand in a clock is spun. Suppose that we now note the minute at which the hand comes to rest.(a) Suppose that the minute hand is very loose so the hand is equally likely to come to rest anywhere in the clock. What are the probabilities of the...
Please do by hand. Thanks in advance.
8. Let X and Y be random variables with a bivariate normal distribution with parameters • px = 5 • Ox= 3 • My = 3 • Oy = 2 • p=.4 a) Find the expected value and variance of Z=4X-Y. b) Find the covariance of X and Z. c) Identify the distribution of Y. d) Identify the distribution of Y|X = 5.
2. A particle moves in the x-y plane. Its coordinates are given as functions of time t(2 0) b x(t)-R(at-sina)t), )Sketch the trajectory of the particle. This is the trajectory of a point on the rim of a wheel y(t)-R(1-cosω t), where R and ω are constants. (a) (3 that is rolling at a constant speed on a horizontal surface. The curve traced out by such a point as it moves through space is called a cycloid. (b) (5 Find...
Calc III... I've tried inputting
(((x+1)^2)+((y-6)^2)+((z+5)^2))-86, and the input in the picture
below,neither are correct.
Answer Preview Entered Result x² + 2x + y? + z² + 10z – 12y – 24 (x^2)+2*x+(y^2)+(z^2)+10*z-12*y-24 incorrect The answer above is NOT correct. (1 point) Find the equation of a sphere if one of its diameters has endpoints: (-6, 10, -7) and (4, 2, -3). x^2+2x+y^2+z^2+10z-12y-24 Note that you must move everything to the left hand side of the equation and that we...
