Generate the first five random numbers (0 to 1) using Linear Congruential method. Given: a = 7, c = 6, m = 17, X0 = 110
1 please answer this question by code of R studio
Create a numeric vector (which is x) starts from -2 to 3 by .1 (increment).
1. How many elements did x have?
2. let s = 6. How to extract the first s elements of x? How to extract the last s elements of x?
3. How to extract all the elements of x that are within .6 of the median of x?
A wireless data terminal has three messages waiting for transmission. After sending a message, it expects an acknowledgement from the receiver. When it receives the acknowledgment, it transmits the next message. If the acknowledgment does not arrive, it sends the message again. The possibility of successful transmission of a message is 'p' independent of other transmissions. Let K = [K1 K2 K3]^T be the three dimensional random vector in which Ki the phone ring is the total number of transmissions when a message i is received successfully. The PMF for the number of transmissions when message i is received successfully is below. For p=0.8, find the expected value vector E[K], the covariance matrix CK, and the correlation matrix RK.

- A wireless data terminal has three messages waiting for transmission. After sending a message, it expects an acknowledgement from the receiver. When it receives the acknowledgment, it transmits the next message. If the acknowledgment does not arrive, it sends the message again. The possibility of successful transmission of a message is 'p' independent of other transmissions. Let K = [K1 K2 K3]^T be the three dimensional random vector in which Ki the phone ring is the total number of transmissions when a message i is received successfully. The PMF for the number of transmissions when message i is received successfully is below. Let J3 = K3-K2, the number of transmissions of message 3; J2 =K2-K1, the number of transmissions of message 2; and J1 = K1, the number of transmissions of message one. Derive a formula for PJ(j), the PMF of the number of transmissions of individual messages.arrow_forwardUse the linear congruential generator to obtain asequence of 10 random numbers, given that a 17, c 43,m 100, and x0 31.arrow_forwardFor Even Roll Number (2)Write standard Basis of P4(x)?arrow_forward
