Answer:

three

Explanation:

Since there are four grades to be represented, any three letter grades can correspond, with a one-to-one mapping, to the elements in the numeric array. Any point that is not represented can be given to the fourth letter grade.

This is also possible because it has been verified that all scores are between 0 and 10. Not more.

Hope this helps!

Answer:

1 PROCESSOR :

(1 × 2.56 × 10^9) + (12 × 1.28 × 10^9) + (5 × 2.56 × 10^8) / 2 GHz = 9.6 s

2 PROCESSORS :

(1×2.56×10^9)+(12×1.28×10^9)/0.7×2 + (5 × 2.56 × 10^8) / 2 GHz = 7.04 s

Speed -up is 1.36

4 PROCESSORS :

(1×2.56×10^9)+(12×1.28×10^9)/0.7×4 + (5 × 2.56 × 10^8) / 2 GHz = 3.84 s

Speed -up is 2.5

5 PROCESSORS :

(1×2.56×10^9)+(12×1.28×10^9)/0.7×8 + (5 × 2.56 × 10^8) / 2 GHz = 2.24 s

Speed -up is 4.29

Explanation:  

The following formula is used in this answer:
