Answer:
10 seconds
Step-by-step explanation:
I am not exactly sure what the question is, but if you are asking how much time it would take to print 300 copies, you would first set up an equation and solve for x.
450/15 = 300/x
x = 10
Convert to improper fraction then add together.
2 3/4 yards = 11/4
1 1/2 yards = 3/2
Then convert 3/2 into quarters = 6/4
Then add together 11/4 + 6/4 = 17/4 and convert back to mixed number
17/4 = 4 1/4 yards
That is cross mulpication
Answer:
that put into the advanced course is 396.75
Step-by-step explanation:
The computation of that put into the advanced course is shown below:
P(X>60)
= P((X - mean) ÷ s > (60 - 50) ÷ 10)
= P (Z > 1)
= 0.1587
It could be checked by the standard normal table
Now that put into the advance course is
= 2,500 × 0.1587
= 396.75
Hence, that put into the advanced course is 396.75
Look at the right and see how the numbers are going down 1,000 each number.
I hope this helps you out
