Julio is trying to decide between 4 different vendors for a new it system. vendor a is less expensive than vendor c. vendor c is more expensive than vendor b. vendor b is less expensive than vendor d. vendor d is less expensive than vendor a. if julio wants to purchase the least expensive system, which vendor will he pick?

Awell-diversified portfolio needs about 20-25 stocks from different categories.

You need to design a circuit that implements the functions in the following table: s0 s1 function0 0 a + 10 1 a – b1 0 a + b1 1 a – 1s0 and s1 are 1-bit control inputs to select the function of the circuit. inputs a and b are 4-bitnumbers in 2s complement form. the output is also a 4-bit number in 2s complement form.you are allowed to use only one ttl 7483 4-bit adder to implement all the functions. but anynumber of other components (except the adder) can be used.hint: design a combinational logic circuit to modify the input b and the “carry input” of theadder depending on the control inputs s0 and s1.important: lab grade will depend on the working of the circuit & will be checked of by your labinstructor.1. is the output valid for the following input combinations: a. s0 = 0, s1 = 0, a = 7, b = 3? b. s0 = 0, s1 = 1, a = 7, b = 3? c. s0 = 1, s1 = 0, a = -4, b = -5? d. s0 = 1, s1 = 1, a = -8, b = 6? 2. what is the range of inputs (for both a and b) that will produce the valid output for all the functions?

Which statement is true of web-based social media? a.they allow consumers to interact with and update content. b.they cannot be updated easily, as compared to print media. c.they are expensive to produce and maintain, as compared to print and television. d.they can exist independent of the internet.
