Answer:

Well, I would definitely advise him to buy USB hubs.

Explanation:

USB hub is a device that can give additional USB slot for the user just by consuming one single slots. In recent years, USB hubs can contain more than 9 slots with different variety, including HDMI and DVI that is required by this particular friend.

Using this device will make it easier to plug in and plug out all the devices he wants to his laptop since it all connected to one single hub.

Since he only has the budget under 100$ , Dell DA300 6-in-1 USB-C Hub could be a good option for Him.

(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:

#1

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

print("You entered: "+service)

#2

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

<em>if service.lower() == "oil change":</em>

<em>    print("Cost of oil change: $35")</em>

For Car wash

<em>elif service.lower() == "car wash":</em>

<em>    print("Cost of car wash: $7")</em>

For Tire rotation

<em>elif service.lower() == "tire rotation":</em>

<em>    print("Cost of tire rotation: $19")</em>

Any service different from the above three, is invalid

<em>else:</em>

<em>    print("Invalid Service")</em>

<em></em>

Write a SQL statement to display the WarehouseID, the sum of Quantity On Order, and the sum of QuantityOnHand, grouped by Wareho
mariarad [96]

Answer:

The corrected question is:

Write an SQL statement to display the WarehouseID, the sum of QuantityOnOrder and sum of QuantityOnHand, grouped by WarehouseID and QuantityOnOrder. Name the sum of QuantityOnOrder as TotalItemsOnOrder and the sum of QuantityOnHand as TotalItemsOnHand. Use only the INVENTORY table in your SQL statement.

Answer to this corrected question:

SELECT WarehouseID,

SUM(QuantityOnOrder) AS TotalItemsOnOrder,

SUM(QuantityOnHand) AS TotalItemsOnHand

FROM INVENTORY

GROUP BY WarehouseID, QuantityOnOrder;

According to the given question:

SELECT WarehouseID,

SUM(QuantityOnOrder) + SUM(QuantityOnHand) AS TotalItemsOnHand    

FROM INVENTORY

GROUP BY WarehouseID, QuantityOnOrder;

Explanation:

  • In the SQL statement SELECT statement is used to select the data from the table. Here the SELECT statement is used to select WarehouseID, Sum of the columns QuantityOnOrder and QuantityOnHand from INVENTORY table.
  • The sum of QuantityOnOrder and QuantityOnHand columns are given the name of TotalItemsonHand (In case of the corrected question the sum of column QuantityOnOrder is named as TotalItemsOnOrder and the column QuantityOnHand is named as TotalItemsOnHand ) using Alias AS. Alias is the temporary name given to the columns or table to make them  more readable.
  • GROUP BY statement is used to arrange or "group" same data and is often use with aggregate functions like SUM function here. So the grouping here is done based on two columns WarehouseID and QuantityOnOrder.
  • SUM function in this SQL statement is an aggregate function to calculate the sum of all value in the columns QuantityOnOrder and QuantityOnHand.
