Answer:

I attached the answer in the picture

Explanation:

Logical True and Logical False

These are kinda strange operations. Logical true always results in True and logical false always results in False no matter the premise. These operations are often referred to as “always true” and “always false”.

Binary Operators

Binary operators require two propositions. We’ll use p and q as our sample propositions.

Negation

The negation operator is commonly represented by a tilde (~) or ¬ symbol. It negates, or switches, something’s truth value.

We can show this relationship in a truth table. A truth table is a way of organizing information to list out all possible scenarios.

AND

The AND operator (symbolically: ∧) also known as logical conjunction requires both p and q to be True for the result to be True. All other cases result in False. This is logically the same as the intersection of two sets in a Venn Diagram.

Implication

Logical implication (symbolically: p → q), also known as “if-then”, results True in all cases except the case T → F. Since this can be a little tricky to remember, it can be helpful to note that this is logically equivalent to ¬p ∨ q (read: not p or q)*.

Keeping track of common files by using a lot of computers and mobiles all through the day may be hard. A good example is when you synchronized your mobile and computer devices. If you check an email using your computer, it will also appear in your smartphone. This will be a lot easier to track your email through both of your devices than having not to be synced at all.

In cell I8, enter a nested logical function to display Need to Remodel if the apartment is unoccupied (No) AND was last remodele
galina1969 [7]

Answer:

The Function is given as

=IF(AND(E8="No",G8>10),"Need to remodel","No Change")

Explanation:

The syntax of the IF condition in excel is given as

IF(Test,If true,If false)

So here the test is an and component such that the house has to be unoccupied which is indicated as E8 because the E column contain the occupancy of the apartments, and the G8 is the last remodeling time, so the test statement is the AND operation of the conditions as

E8="No" indicating that house is unoccupied

G8>10 indicating that the last remodelling was more that 10 years ago

So the test is given as

AND(E8="No",G8>10)

Now the statement if the test true is the recommendation for to remodel, so

"Need to remodel"

Now the statement if the test is false is given as

"No Change"

So the overall function becomes

=IF(AND(E8="No",G8>10),"Need to remodel","No Change")
