Suppose a book author can be identified by an AuthorID and each book can be identified by an ISBN. Besides the identifier, an au

Scrat [10]

Answer:

a) We know that atleast one or more author writes a book.

Symbol to indicate one or more is (B)

So the correct option is B

b) We know that zero to multiple books are written by any author.

Symbol to indicate zero or more is (A)

So the correct option is A

c) The fourth option is correct if we replace by many to many relationship and generate a new entity.

So the relationship betweem author and contract is one to many. So we know that there is atleast one author that represent in symbol d and books has atleast 0 that represent in symbol c.

So Fourth Option is correct d at blue side and c at red side.

d) There are two forirgn keys in table Contract one is from AuthorId and other is ISBN.

So correcct option is C

A positive integer is called a perfect number if it is equal to the sum of all of its positive divisors, excluding itself. For e

Ad libitum [116K]

i = 1

while i < 10001:

total = 0

x = 1

while x < i:

if i % x == 0:

total += x

x+=1

if total == i:

print(str(i)+" is a perfect number")

i += 1

When you run this code, you'll see that 6, 28, 496, and 8128 are all perfect numbers.

In cell F29, use an IF function to display the correct Shipping Charge, based on the amount of the Discounted Total. If the Disc

sladkih [1.3K]

Answer:

= IF(B29 >= B28,0,(0.05 * B29))

Explanation:

Given

Free Shipping Minimum = B28

Shipping Charge = F29

Required

Write a formula in F29 to calculate the total shipping charge based on the condition in the question.

To solve this, the following assumption needs to be made.

It'll be assumed that cell B29 contains the value for Discounted Total.

So,

Discounted Total = B29

The condition in the question says

1. If Discounted Total (B29) is greater than or equal to the Free Shipping Minimum (B29), then Shipping Charge (F29) is 0

This can be represented as

If(B29 >= B28)

F29 = 0

2. Else (i.e. if (1) above is false), Shipping Charge (F29) equals 5% of Discounted Total (B29)

This can also be represented as

F29 = 0.05 * B29

Writing the formula in (1) and (2) together in Excel format;

= IF(B29 >= B28, 0, (0.05 * B29))

The above formula will give the desired result based on the condition in the question.

Take for instance;

Free Shipping Minimum = B28 = 28

Discounted Total = B29 = 30

Since 30 >= 28, the value of F29 will be 0 because it satisfies condition 1.

But if

Free Shipping Minimum = B28 = 30

Discounted Total = B29 = 28

Since 28 < 30, the value of F29 will be 5% of 28 = 1.4 because it satisfies condition 2
