In the town, the weather pattern has three categories each day: Windy, Rainy or Sunny. The weather pattern each day follows a Markov chain model. If it is windy on a day, the following day will be sunny for sure; if it is rainy, the following day will be rainy with probability 0.25 otherwise sunny; and if it is sunny, the following day will be windy with probability 0.25, Rainy with probability 0.25 and sunny otherwise. A worker is paid $175, $125 and $75 on days work depending on if it is Windy, Rainy or Sunny, respectively.
a. Write the transition matrix for this weather pattern
b. How much does the worker get paid on an average day?

Jack wants to build a circuit to shift 4 bits (I0 to I3 from left to right) in a circular way. One extra bit (S) is used to control the direction of shifting. When S = 0, the bits should be shifted left, otherwise right. The outputs are O0 to O3 from left to right. For example, when shifted right, 0011 would become 1001; when shifted left, 0011 would become 0110.
Please help Jack get started by providing the fourth and 20-th row of the truth table for O2, and the fourth and 20-th row for O1. Each row should be formatted as (S,I0,I1,I2,I3,Output) and the rows should be separated by comma. The answer should look like (0,0,0,0,0,0),(1,1,1,1,1,1),(0,0,0,0,0,0),(1,1,1,1,1,1). All inputs as 0 is the first row and all inputs as 1 is the last row in the truth table.

An unbalanced three-phase wye-connected and grounded load is connected to a balanced three-phase four-wire source. The load impedances are Za = 14+j3 Ω , Zb = 5-j24Ω and Zc =1+j14 Ω and the phase a line voltage has an effective value of 18 Kv: use line-to-neutral voltage of phase A as a reference.
Find the line and neutral current, also find the reactive power delivered to load and power factor.
