Hi!
First, find the total percent of vehicles with at least 3 people.
15% + 7% + 3% = 25%
Now find 25% of 420
Set up a proportion and cross multiply to solve.

25 * 420 = 10500
10500/100 = 105
The answer is 105 vehicles contained at least 3 people.
Hope this helped! :)

Answer:

Step-by-step explanation:
In order to evaluate a function at a given x-value, plug in that value into the actual function

Answer: Answer: x^2 - 1 is not a polynomial as after simplifying it there will be no variable.
Step-by-step explanation:
Answer:
we determine that none of the ordered pair is a solution of
as none of the ordered pairs satisfy the equation.
Step-by-step explanation:
Considering the equation

- Putting (-5,2) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (0,-5) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (5,1) in the equation


∵ L.H.S ≠ R.H.S
FALSE
- Putting (7,5) in the equation


∵ L.H.S ≠ R.H.S
FALSE
From the above calculations, we determine that none of the ordered pair is a solution of
as none of the ordered pairs satisfy the equation.
