Answer:
There are 35990 ways in which 2 or 3 nodes fail
Step-by-step explanation:
Given : A computer network has 60 switching nodes.
To Find : In how many ways can 2 or 3 nodes fail?
Solution:
We are supposed to find no. of ways can 2 or 3 nodes fail.
So, we will use combination here .
No. of ways can 2 or 3 nodes fail=
Formula :
No. of ways can 2 or 3 nodes fail=
=
Hence there are 35990 ways in which 2 or 3 nodes fail
Answer:
Cost before tax = $25,665.57
Step-by-step explanation:
Given:
Costs of car = $27,449.80 including sales tax
Sales tax = 6.5%
We need to find cost of car before tax.
6.5% of car cost =
Where x is the percentage value.
6.5% of car cost =
6.5% of car cost =
6.5% of car cost =
The tax on the car is $1784.237.
So, the cost of the car before tax is.
Cost before tax = cost of car - cost of tax
Cost before tax = 27449.80 - 1784.237
Cost before tax = 25665.57
Therefore, the cost of the car before tax is $25,665.57
Answer:
The rate of jet in still air is 850 mile per hour
The rate of jetstream is 150 mile per hour.
Step-by-step explanation:
Given as :
The distance cover against jetstream = 5600 miles
The time taken against Jetstream = 8 hours
The distance cover with jetstream = 4000 miles
The time taken with the jetstream = 4 hours
Now , let The speed of jet in still air = x mph
The speed of jetstream = y mph
As , Speed =
So, According to question
x - y =
Or, x - y = 700 mph
x + y =
Or, x + y = 1000 mph
So, ( x - y ) + ( x + y ) = 700 + 1000
Or, 2 x = 1700
∴ x = = 850 mph
And y = 1000 - 850 = 150 mph
Hence The rate of jet in still air is 850 mile per hour and The rate of jetstream is 150 mile per hour. Answer
