Using proportions, it is found that:
2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.
3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For each of Alan and Bree, we have to find the proportions of words typed per second and mistakes per second.
Then, for Alan:
- Words typed per second: 5/6 = 0.83.
- Mistakes per second: 2/6 = 0.33.
For Bree:
- Words typed per second: 9/8 = 1.13.
- Mistakes per second: 3/8 = 0.375.
Then:
2. Bree types at a faster rate, as her ratio of 1.13 words per second is greater than Alan's rate of 0.83 words per second.
3. Bree also makes mistakes at a raster rate, as her rate of 0.375 mistakes per second is greater than Alan's rate of 0.33 mistakes per second.

We know that
the points where the graph of the function crosses the y-axis is when <span>a function is evaluated with a zero, these points represent the y-intercept of the function
</span>
therefore
the answer is
Represent the y-intercept of the function
I believe it is B. Sorry I’m not the best at math but hope this helps !!
100,000,000+70,000,000+6,000,000+ 900,000+40,000+5,000+500+90+6= 176,945,596
I hope this helped
