Transactions to a computer database are either new items or changes to previous items. The addition of an item can be completed less than 100 milliseconds 81% of the time, but only 20% of changes to a previous item can be completed in less than this time. If 30% of transactions are changes, what is the probability that a transaction can be completed in less than 100 milliseconds? Round your answer to two decimal places (e.g. 98.76).
Answers
Answer:
There is a 62.7% probability that a transaction can be completed in less than 100 milliseconds.
Step-by-step explanation:
This a probability problem.
We have the following probabilities:
-70% probability that a transaction is an addition of an item.
-30% probability that a transaction is a change to an item
-81% probability that an addition can be completed in less than 100 milliseconds
-20% probability that change can be completed in less than 100 milliseconds
The probability P that a transaction can be completed in less than 100 milliseconds is:
In which is the probability that the transaction is an addition and it takes less than 100 milliseconds. So
is the probability that the transaction is a change and it takes less than 100 milliseconds. So
So
There is a 62.7% probability that a transaction can be completed in less than 100 milliseconds.

Answer:
length: 14.2 ft; width 4.2 ft.
Step-by-step explanation:
Let x represent the length of the rectangle in feet. Then x-10 represents the width, and the area is ...
area = length×width
60 = x(x -10) . . . . . substitute the expressions for area, length, width
60 = x² -10x
85 = x² -10x +25 . . . . add (10/2)² to complete the square
85 = (x -5)² . . . . . . . . . rewrite as a square
√85 = x -5 . . . . . . . . . take the square root. Only the positive root is useful for this problem
x = 5 + √85 ≈ 14.2
x-10 = 4.2
The length and width of the rectangle are 14.2 ft and 4.2 ft.

Answer:
21.45 miles
Step-by-step explanation:
Key:
t=time
d=distance
We need to find the time the lion ran first.
The time the lion ran:
13.75=50•t
13.75=50t
-50t=-13.75
t=-13.75•-1/50
t = 0.275
So the lion ran in 13.75 miles in 0.275 of an hour.
Now, we need to figure out the cheetah.
0.275•78=21.45 miles
I hope this helps :-)
