(1) Prompt the user for an automobile service. Output the user's input. (1 pt) Ex: Enter desired auto service: Oil change You en

Pavlova-9 [17]

Answer:

In Python:

service = input("Enter desired auto service: ")

print("You entered: "+service)

if service.lower() == "oil change":

print("Cost of oil change: $35")

elif service.lower() == "car wash":

print("Cost of car wash: $7")

elif service.lower() == "tire rotation":

print("Cost of tire rotation: $19")

else:

print("Invalid Service")

Explanation:

First, we prompt the user for the auto service

service = input("Enter desired auto service: ")

Next, we print the service entered

print("You entered: "+service)

Next, we check if the service entered is available (irrespective of the sentence case used for input). If yes, the cost of the service is printed.

This is achieved using the following if conditions

For Oil Change

if service.lower() == "oil change":

print("Cost of oil change: $35")

For Car wash

elif service.lower() == "car wash":

print("Cost of car wash: $7")

For Tire rotation

elif service.lower() == "tire rotation":

print("Cost of tire rotation: $19")

Any service different from the above three, is invalid

else:

print("Invalid Service")

A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter

trapecia [35]

Answer:

5 Letters

Explanation:

So we need 12 distinct codes made of a single letter or a pair of letters.

What would be the least number of letters?

Lets try with 3 letters A, B and C

The possible combinations are: A, B, C, AB, AC, BC

These are 6 codes and we need 12 so lets try more A, B, C and D

The possible combinations are: A, B, C, D, AB, AC, AD, BC, BD, CD

These are 10 codes and we need 12 so lets try more A, B, C, D and E

The possible combinations are:

A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE

Finally we got 15 distinct codes which are more than 12 so the least number of letters needed are 5.

Using formula:

Four letters = 4C1 + 4C2 = 4 + 6 = 10

Five letters = 5C1 + 5C2 = 5 + 10 = 15

You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav

asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

RAID 0: does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

RAID 1: Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

RAID 5: Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is $\frac{n-1}{n}$ of the total disks: $\frac{7}{8}$ of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.
