When analyzing data sets in pre-statistics courses, you may often need to find the range of the numbers of a given set. The value of the range indicates the degree of variety within the data set. It is a common math problem that students may encounter on many standardized tests. Once yo...
Learn how to find the value or change in value of quantities that are linearly related, and see examples that walk through sample problems step-by-step for you to improve your math knowledge and skills.
Sample mean: the average value in asample. Population mean: the average value in apopulation. Other Types Thereareother types of means, and you’ll use them in various branches of math. However, most have very narrow applications to fields like finance or physics; if you’re in elementary...
Step 2:Findf(x+h),which we will plug into our difference quotient,f(x+h)−f(x)h. Step 3: limh→0f(x+h)−f(x)h, How to Find the Derivative of a Function Using the Limit of a Difference Quotient: Vocabulary Derivative:The derivative of a function i...
This confused me at first. I originally thought the derivative would require us to bring down "u". No -- the derivative of e^foo is e^foo. No more. But if foo is controlled by anything else, then we need to multiply the rate of change by the conversion factor (d(foo)/dx) ...
1. How to Find LCM by Listing Multiples Think of the “Listing Multiples Method” as a bit like sorting out toys or candies by type or color. To start, you choose the numbers you want to find the LCM for. As an example, let’s choose 5 and 6. ...
The APR is given as an annual rate–but card issuers typically calculate the interest that you owe on a daily basis. To find this daily interest amount, they will divide the APR by 365 to generate the DPR. So, if a card has an APR of 11.24%: divide 11.24% by 365. The resulting ...
Just as we would ask students to turn to their peers in a face-to-face learning environment andmake an estimate, we asked the educators in the webinar tomake an estimateand share it synchronously in the chat. What we found in our live webinar as well as what you might also find with ...

Explanation: A common strategy to solve this question is to subtract four from the y-values of the points and add seven to the x-values of the points and then try to find the slope of the new line. However, the key to solving this problem is recognizing that a line translated means ...
