The slope is 20/13. Yes, the slope is steeper because without the lip on the slide you would travel downward faster.
<h3>
Answer: $5.16</h3>
==================================================
Work Shown:
72% = 72/100 = 0.72
72% of $3.00 = 0.72*3.00 = 2.16
The price increases by $2.16 to get the final answer of 3.00+2.16 = 5.16 dollars
-------
We can find this answer through this alternative route:
1.72*3 = 5.16
The multiplier 1.72 represents an increase of 72% since 1.72 = 1 + 0.72 = 100% + 72% = 172%
The prime numbers on the dice are 1,2,3,5 and 7 , the theoretical probability is

, which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is

, which is 75%, the difference between the experimental probability and the <span>theoretical probability is 12.5%.</span>
