Answer:
Evaluating the piecewise function when X =3, we get f(3) = 7
Step-by-step explanation:
Given the following piecewise function
f(x)= { 2x+1; where x > 0
-3 when x ≤ 0
Evaluate the function when X = 3
We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0
We can't use -3, because x ≤ 0, and 3 is not less than 0.
Now, evaluating the function:
So, Evaluating the piecewise function when X =3, we get f(3) = 7

Shaniya owns a company that rents cars called Car Go. The following bar graph summarized the type of vehicles rented last week. Based on the data, what is a reasonable estimate of the probability that a van is the next of the vehicle rented?
The graph is attached down
Answer:
The probability that a van is the next type of vehicle rented is 25% or
Step-by-step explanation:
Probability of an event = outcomes of the event ÷ total outcomes
From the attached graph
∵ The number of cars rented is 8
∵ The number of vans rented is 5
∵ The number of trucks rented is 4
∵ The number of motorcycles rented is 3
- Add all of them to find the number of vehicles rented
∴ The number of vehicles rented = 8 + 5 + 4 + 3 = 20
To find the probability of that a van is the next type of vehicle rented divide the number of the vans by the number of the vehicles
∵ The number of vans = 5
∵ The number of vehicles = 20
∴ P(van) =
- Divide up and down by 5 to simplify it
∴ P(van) =
- To change it to percent multiply it by 100%
∴ P(van) = × 100% = 25%
The probability that a van is the next type of vehicle rented is 25% or
