<u>So the domain is the list of x-values that are possible on a line.</u>
In this case since time is the x-axis, this means that he ran the race from 0 to 11 seconds, eliminating the first two options.
Now, a lot of races will have times going into the decimal places (tenths, hundredths, thousandths, etc). With integers however, they are whole numbers, and fractions and decimals are not considered whole numbers. With this info, we can eliminate the last option.
With the other three options eliminated, <u>your answer is C. Real numbers from 0 to 11.</u>
The point (4,7) is the only one that can be plugged into the equation and work. in this case when 4 is plugged in as X & Y is plugged in at 7 we get that 7=7, which is a true statement.
Using proportions, it is found that $55.7 billion was donated to educational organizations.
<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.
Of the $371 billion donated in total, 15% went to educational organizations, hence the amount is given by:
A = 0.15 x 371 = $55.7 billion.
Hence $55.7 billion was donated to educational organizations.
