In (A) statistics class Wilson's students earn a higher ratio of a's to b's.
<h3>
What are ratios?</h3>
- A ratio in mathematics describes how many times one number contains another.
- For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.
- Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
To find the higher ratio:
Given -
- Geometry class = a:b = 12:20 = 3:5
- Statistics class = a:b = 11:15
As we can observe that 3:5 < 11:15.
Therefore, in (A) statistics class Wilson's students earn a higher ratio of a's to b's.

Answer:
5 pounds per bag simplified from 30 pounds per 6 bags

Answer: 12 men would be needed to repair the same road in 3 1/3 hrs. Inverse proportion because usually in work,food and time its inversly proportional.
8 hours --> 5 men
1 hour --> 5*8 = 40 men
3 1/3 hours --> 40/ (3 1/3) men
--> 12 men
There are 
ways of picking 2 of the 10 available positions for a 0. 8 positions remain.
There are 
ways of picking 3 of the 8 available positions for a 1. 5 positions remain, but we're filling all of them with 2s, and there's 
way of doing that.
So we have
The last expression has a more compact form in terms of the so-called multinomial coefficient,
Answer:
A repeating decimal can be written as a fraction using algebraic methods, so any repeating decimal is a rational number.
Marco is wrong cuz its not repeating
