Answer:
The correct code for this question:
g=float(input("Enter your English test grade:")) #take input from user.
#check conditions
if (g>=100 and g<=90):
print ("A")
#g greater then equal to 100 and less then equal to 90.
if (g>=89 and g<=80):
print("B")
#g greater then equal to 89 and less then equal to 80.
if (g>=79 and g<=70):
print("C")
#g greater then equal to 79 and less then equal to 70.
if (g>=69 and g<=65):
print("D")
#g greater then equal to 69 and less then equal to 69.
if(g<=64):
print("F")
#g less then equal to 64.
else:
print ("Not a grade")
#not a grade or fail.
Explanation:
In this program, we use to take a value from the user and check the value from the various conditions. To check all the condition we use if-else statement and AND operator that check to the range to together.
If -else is a conditional operator. In that, If block is used to check the true part and else part takes false value, and AND is a logical operator that check the two range together
Answer:
The TCP/IP is the transmission control protocol and internet protocol and in the TCP/IP model the transport layer is the second layer.
The primary responsibility of this layer is that it is basically used to deliver messages to the host and that is why it is known as end to end layer.
It basically provide the point to point connection between the destination to server host for delivering the various types of the services efficiently and reliably.
In the TCP/IP model the transport layer are basically responsible for transferring the data or service error free between the server to destination host.
Liquidity Effect. When the Fed pursues a tight monetary policy, it takes money out of the system by selling Treasury securities and raising the reserve requirement at banks. This raises interest rates because the demand for credit is so high that lenders price their loans higher to take advantage of the demand.
