Ответ:
The average number of machine cycles per instruction for this microprocessor is 5.8.
Step-by-step explanation:
To find the average number of machine cycles per instruction for this microprocessor, we multiply each number of cycles for it's relative frequency.
We have that:
25% require 2 cycles.
20% require 3 cycles.
17.5% require 4 cycles.
12.5% require 8 cycles.
25% require 12 cycles.
So the average number is:
Ответ:
Option C is correct.
Step-by-step explanation:
Given: terms of the Sequence is -2 , 4 , 10 , 16 , ...
To find: 50th term of the sequence.
Clearly given Sequence is an AP.
So, First term, a = -2
Common difference, d = 16 -10 = 6
Now we know that,
Therefore, Option C is correct.
