How do you find missed frequency if median and mode are given

The average of a set of numbers is defined as the sum of those numbers divided by the number of numbers. If the average is given, multiply that by number of items in the set including the missing number. Subtract the sum of given numbers from this quotient and the missing number is revealed.

Given the average,find the missing numbr in a set by following these steps: 1.Multiply the average by the number of items in the set. 2.Add the given numbers ni the set. 3.Find the difference of the product in step 1 and step2.

The answer depends on what information you do have.

find the frequency before finding the percent total -_- :)

That really depends on what information is given.

To calculate the frequency density we will simply divide the frequency by the class width.

valid percent = Frequency/# of non missing cases x 100

Convert it.

The inverse of frequency is the period, which is the distance between two consecutive crests. If you are given frequency (f), period = 1/f

you have to count up all of the addends

The velocity of the light waves must be given before the frequency can be find.

The formula that links frequency to wavelength is v = f * lambda, where v is speed with units of meters per second (m/s), f is frequency with units of hertz (Hz or 1/s), and lambda is the wavelength with units of meters (m). Given frequency and speed, one can easily find the wavelength by solving the given equation to get lambda = v / f. Conversely, if given wavelength and speed, one can easily find the frequency by solving the given equation to get f = v / lambda.

A=14,b=8

The median is the middle number. If there is an odd number of numbers in the set, the median is the middle number, and the only way to find the missing number is if the median is the missing number. If there is an even number of numbers in the set, the median is the average of the two middle numbers, and the only way to find the missing number is if the median is one of those two numbers. If it is, you can take the median and the one of the two numbers you know. Use the formula (# +#)/2=median and solve.

All the angles of a square are 90 degrees.

* To find the mean (or average) of a standard frequency table, you must firstly cross-multiply the frequncies with the independent variable in the left column. * Then, add up these products and divide by the total number of frequencies. * For grouped frequency tables, you must find a mid-point, a half-way value in each group, before cross-multiplying.

That will depend on the information given as for example if you are given its width and area then in order to find its length divide the width into the area.

You can use the equation v=fw. that is velocity (in meters per second) equals the frequency (in hertz) times the wavelength (in meters). so you can find the velocity of a wave with the frequency and the wavelength.

Missing....? But the answer to find the missing is normally either "algebra" or "find another equation to use."

Wavelength (Î») is the distance between repeating units of a wave of a given frequency. Usually its shown as measured from the top of one wave to the next. To find the wavelength for a given frequency, the formula is: C=Î»v C is the speed of light (3.00 x 108) and v is the frequency
