The forsite company is screening three ideas for new services. resource constraints allow only one idea to be commercialized at the present time. the following estimates have been made for the five performance criteria that management believes to be most important: rating performance criterion service a service b service c capital equipment investment required 0.3 0.8 0.8 expected return on investment (roi) 0.5 0.9 0.7 compatibility with current workforce skills 0.6 0.4 0.2 competitive advantage 0.8 0.8 0.8 compatibility with epa requirements 0.2 0.7 0.7 a. calculate a total weighted score for each alternative. use a preference matrix and assume equal weights for each performance criterion. let the total of the weights equal 100. (enter your responses as integers.)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

a - base

b - exponent
