Answer 1

Answer:  3) 6:23      4) .42        5) .30

Step-by-step explanation:

3) Less than 3 means 0, 1, or 2 cars

   0, 1, or 2 cars            Total cars

=     2 + 1 + 3      :      2 + 1 + 3 + 7 + 10

=       6               :           23

4) Less than 6 means: 1, 2, 3, 4 or 5

$\dfrac{1,2,3,4,5}{Total}\quad =\dfrac{5}{12}\quad =\large\boxed{0.42}$

5) Monday = 150, Friday = 150, Total = 1000

$\dfrac{\text{Monday + Friday}}{Total}\quad =\dfrac{150+150}{1000}\quad =\dfrac{300}{1000}\quad =\large\boxed{0.30}$
