Based on the times that the machine produces cookies that have the optimal amount of chips, the proportion produced daily with the optimal number of chips is 62.5% or 0.625.
<h3>What is the proportion of cookies with optimal chocolate chips?</h3>
This can be found by the formula:
= (Hours that optimal cookies are produced) / Hours that the machine runs per day
5:30 am is the same as 5.5 hours because 30 minutes is half an hour.
1:30 pm is also the same as 13.5 hours by the above rule and in 24 hour notation.
Proportion of optimal cookies is therefore:
= (11 am - 6am) / (13.5 - 5.5)
= 5 / 8
= 0.625
= 62.5%

The answer is five times a number, subtracted from four, is eleven.
A stem and leaf plot is a table where each of the data is divided into two parts. The stem, that is the first digit and the leaf is the last digits. Let's say that we have the following set of data.
If we want to make a stem and leaf plot of that data, we first write a column where we place the first digit of each number without repetition, like this:
These are the stems. Now the leaves are the last digit of each number put in order next to the corresponding first digit, like this:
