Correct Answer:
c.
SELECT InvoiceNumber, VendorName
FROM Invoices JOIN Vendors ON Invoices.VendorID = Vendors.VendorID
WHERE InvoiceTotal IN (SELECT MAX(InvoiceTotal) FROM Invoices)
Explanation:
All options only differ on the WHERE clause:
a: WHERE InvoiceTotal = MAX(InvoiceTotal)
Fails because aggregate functions (like MAX, COUNT, etc) have to be used on the SELECT clause.
b: WHERE InvoiceTotal = (SELECT MAX(InvoiceTotal))
Fails because the SELECT clause is incomplete.
c: WHERE InvoiceTotal IN (SELECT MAX(InvoiceTotal) FROM Invoices)
This one is correct, and returns the InvoiceNumber and VendorName register with the largest value on the InvoiceTotal field.
Answer:
a) 228
b) 940
c) 255
Explanation:
To convert a hexadecimal number to decimal, multiply each hex digit by 16^(position-1) and add the components.
For example, 0x 34 = 3* 16^(2-1) + 4*16^(1-1) = 48 + 4 = 52
Evaluating the given numbers:
a) 0xE4 =>
E corresponds to 14. So the decimal representation is 14*16 + 4 = 228
b) 0x3AC =>
A corresponds to 10 and C to 12. So the decimal representation is 3*16^2 + 10*16 + 12 = 940
c) 0xFF =>
F corresponds to 15. So the decimal representation is 15*16 + 15 = 255

Explanation:
Answer:
1080 x 1920
800 x 600
Explanation:
These are the screen sizes that you can find in the list of the screen sizes, which can be easily found in the document that lists all the screen sizes. You will certainly find the 1080 x 1920 and also the 800 x 600, however, you will not find the 320 x 240 and 800 x 600. The last two are the standard screen sizes and hence are not the correct options. The correct options are as listed above.
