A ratio shows us the number of times a number contains another number. The proportion of students that are in middle school and chose french fries is 0.14.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
Given that the number of students are in middle school and choose french fries is 56, while the total number of students is 400. Therefore, the proportion of students that are in middle school and chose french fries are,
Proportion = (Number of students in middle school who choose french fries) / (Total number of students)
= 56 / 400
= 0.14
Hence, the proportion of students that are in middle school and chose french fries is 0.14.

I believe the correct answer from the choices listed above is the third option. The first step on solving 5 – 2x < 8x – 3 would be 5 < 10x – 3. The first step is to add both sides with the term 2x. Hope this answers the question. Have a nice day.
Answer:
See Below.
Step-by-step explanation:
We are given the function:
And we want to show that it has at least one zero between <em>x</em> = 1 and <em>x</em> = 2.
Because the function is a polynomial, it is everywhere continuous.
Evaluate the function at <em>x</em> = 1 and <em>x</em> = 2:
And:
Therefore, because the function changes signs from <em>x</em> = 1 to <em>x</em> = 2 and is continuous on the interval [1, 2], by the intermediate value theorem, there must exist at least one zero in the interval.
