The probability that a wildcat well will be productive is 1/13. Assume that a group is drilling wells in various parts of the country so that the status of one well has no bearing on that of any other. Let X denote the number of wells drilled to obtain the first strike.
(A) Verify that X is geometric, and identify the value of the parameter p.
(B) What is the exact expression for the density for X?
(C) What is the exact expression for the moment generating function for X?
(D) What are the numerical values of E[X], E[X^2], sigma^2, and sigma?
(E) Find P[X greaterthanorequalto 2].

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

pretty sure 750 each month!

step-by-step explanation:

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
