<u>Functions to model reality </u>
There are situations in real life where some variables depend on other(s) and that dependency can be determined as a practical rule or from a well-known theory. The expression who relates those variables are commonly called functions and they become a very useful tool to analyze, explain and predict the behavior of such events.
We know the monthly budget of a company is x dollars. $20,700 out of it is spent on salaries. After deducting salaries, the remaining budget is
One-fifth of it is spent on office supplies, so the required function is
Answer:
The coordinates of point E on CD are .
Step-by-step explanation:
Let be , and . The given ratio can be translated vectorially into this:
And let consider that each point is a vector with respect to origin:
and
Then,
The coordinates of point E on CD are .
Answer:
4 blu-rays
Step-by-step explanation:
*Note: I'm rounding up to full dollars to make this easier. You will get the same answer, whether you round up or not.
First, get rid of the shipping cost from the budget.
$150 - $10 = <u>$140 left for blu-rays</u>
Then divide $140 by $30, which is the price for a single blu-ray to get the number of blu-rays Chris can get.
$140 ÷ $30 ≈ 4.6 repeating. You can't have a fraction of a movie, so Chris can get 4 blu-rays
Firstly, round 63 and you get 60, then, round 42 and you get 40. Finally, add 60 and 40. Your answer will be 100.

A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.
<h3>What is a median?</h3>
A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.
