Answer:
Let P(x) = x is in the correct place
Let Q(x) = x is in the excellent place
R(x) denotes the tool
Explanation:
a) Something is not in the correct place.
P(x) is that x is in the correct place so negation of ¬P(x) will represent x is not in the correct place. ∃x is an existential quantifier used to represent "for some" and depicts something in the given statement. This statement can be translated into logical expression as follows:
∃x¬P(x)
b) All tools are in the correct place and are in excellent condition.
R(x) represents the tool, P(x) represents x is in correct place and Q(x) shows x is in excellent place. ∀ is used to show that "all" tools and ∧ is used here because tools are in correct place AND are in excellent condition so it depicts both P(x) and Q(x). This statement can be translated into logical expression as follows:
∀ x ( R(x) → (P(x) ∧ Q(x))
c) Everything is in the correct place and in excellent condition.
Here P(x) represents correct place and Q(x) represents excellent condition ∀ represent all and here everything. ∧ means that both the P(x) and Q(x) exist. This statement can be translated into logical expression as follows:
∀ x (P(x) ∧ Q(x)
Answer:
Replace
if userAge > 20
with
userAge > 19
Explanation:
if userAge > 20 checks if age is 21, 22, 23, 24........
The else condition which prints "I am a teenager" checks if age is 20, 19, 18....
Notice that 20 is inclusive of the else condition; this shouldn't be because for userAge to be less than 20, 20 isn't inclusive
To solve this,
Replace if userAge > 20 with userAge > 19
So that, the else
The else condition which prints "I am a teenager" checks if age is 19, 18, 17, 16....

Answer:
Most injury crashes in Florida happen in dusk conditions
Explanation:
Dusk is the time of the day when the sun is setting. At this time of the day, the visibility on the roads is less. This time of the day, the number of cars on the roads is also significantly greater. This indirectly means that the possibility of most injury crashes in Florida in dusk conditions considerably increases.
The amount of tourism happening in the state is also a condition that takes part in injury crashes due to increased traffic on the roads.
