Answer: 
Step-by-step explanation:
Number of persons said it is legal to text while driving = 8
Number of persons said it is illegal to text while driving = 804
Total persons sampled = 804+8 = 812
Since probability =
The probability of randomly selecting someone who believes it should be legal to text while driving = 
Required probability =
The product of 12 and x can be displayed as 12x
9 less than 12x is displayed as 12x - 9
Answer: 12x - 9
This problem can be represented in a formula with fractions. To make it more simple, we are converting 5m30s to just pure seconds, which = 154 copies in 330 seconds.
You set up the formula like this: 154/330 = x/60. (it is x/60 because you want to know the x amount of copies per 60 seconds)
Cross multiply, you get 330x = 9240. Divide both sides by 330, you get:
x = 28 copies.
The final answer is 28 copies per minute
21 can go into 44 2 times
