What is the formula for finding work?Work in PhysicsThere can be many forces acting on a body. To find the net effect of all the forces on the body, we have to look at each force individually first, and then add the result of each force....
The formula for finding z-scores is the following: X represents the data point of interest. Mu and sigma represent the mean and standard deviation for thepopulationfrom which you drew yoursample. Alternatively, use the sample mean and standard deviation when you do not know the population values...
Now that you know how to find the average—in other words,how to calculate the mean of a given set of data—it’s time to test what you’ve learned. In this section, we'll give you four math questions that involve finding or using the mean. The first two questions are our own, w...
Put the data set in ascending order. This can be done with software such as Excel, or by hand (for smaller distributions). Use the formula for percentile, and find the appropriate value in the sorted data set. Recall that the formula for finding the {eq}p^{th} {/eq} percentile of ...
Linear approximation is used to estimate the value of a function near a particular point. This is useful when the exact value of the function at that point is difficult or tedious to find. What is the linear approximation formula? The formula for finding the linear approximation of a function...

This would mean that teachers are left with one less year to provide students with the skills for algebraic success. Thus there is a need to focus on elementary level professional development to enhance understanding of math content.Fratt
For finding out the number of students in the class that scored higher or lower than Emily, we will look at the normal distribution table. In this case the Z-value comes to 0.2514. It means that the probability of a score being higher than 0.67 is 25.14%. It shows that approximately 25...
