Answer:
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:
![M = 0.25*2 + 0.2*3 + 0.175*4 + 0.125*8 + 0.25*12 = 5.8](https://tex.z-dn.net/?f=M%20%3D%200.25%2A2%20%2B%200.2%2A3%20%2B%200.175%2A4%20%2B%200.125%2A8%20%2B%200.25%2A12%20%3D%205.8)
Answer:
Sally's method
Step-by-step explanation:
Something squared is a number times itself. The square root is the reverse. Michael's method is wronh because he is dividing by 2 (multiplying by½), which is not how you find the square root.
Answer: 149
Step-by-step explanation:
out of 80 students, 20 said that they prefers cats, then the relative frequency is:
p =20/80 = 0.25
then, out of the 597 students a estimate of:
N = 0.25*597 = 149.25 like cats
We should round it down so we have a whole number, then we have a estimate of 149 students.
Answer:
11
Step-by-step explanation:
23-1=22
22/2=11
For this case we have the following linear equation:
d = 15.7p + 2.0
Where,
p: number of people
d: total bill
We note that the slope of the equation is:
m = 15.7 $ / person
Therefore, the amount of the bill increases if the number of people grows.
Answer:
b) The model predicts that for each additional person at a table, the total bill increases by $ 15.70.
