find the mean of those squared deviations. step 4: finally, take the square root obtained mean to get the standard deviation. q2 what does standard deviation tell you? standard deviation tells us how far is the mean from each observation in the given data set. in other words, it shows ...
is the data set. as we know, a data set or set of values can have more than one mode if more than one value occurs with equal frequency and number of time compared to the other values in the set. hence, here both the number 4 and 15 are modes of the set. example 3: find the...
This is the equation we need to remember. Once we know it, we can rearrange to find the other two.Examples of Working Out Watts, Amps and Volts for Appliances How to Work Out Watts Watts = Volts x Amps e.g. A 120 volt appliance takes 2 amps, what is the power?Power...
Complete the following nuclear equation: ___ + \; _{2}^{4}He \to \; _{20}^{42}Ca + \; _{1}^{1}H. How do you find the period for both cosine and sine function? How do you find the frequency of a tone given a period of 50 milliseconds? How...
sine wave is swept through all the frequencies of interest while an analyzer tracks the output to measure the frequency response. In most cases, the ideal system will produce the same amplitude at all frequencies, so the output equals the input. This is often called a “flat” frequency ...
The equation: F=-Kx is used to define a linear simple harmonic motion (SHM), wherein F is the magnitude of the restoring force; x is the small displacement from the mean position; and K is the force constant. The negative sign indicates that the direction of force...
(to represent the total number of degrees possible in an angle) by the frequency of your wave. Multiply the number that you receive after multiplying the first two variables by the time delay that was given above. When all of these numbers are multiplied together, you will find the phase ...
from Chapter 3 / Lesson 5 12K Did you know that not all years have the same number of days? In this lesson, you'll find out about what a leap year is, how many days it has, and why those extra days are needed. Related to this QuestionWhat...
