3 Mean (two missing frequencies and mode) hindi Explanation YouTube

How To Find Missing Frequency When Mean Is Given - How To Find. Of number/items) so, take the sum of all objects and divide it by no. Find the missing frequencies and the median for the following distribution if the mean is 1.46.

Find the missing frequencies and the median for the following distribution if the mean is 1.46. Aboat goes downstream from one part of the river to another part of river in 16 hours it covers the same distance upstream in 20 hours if the speed of stream is 2 km per hour find. Mean = 2× 1 + 5× 2 + 4× 3 + 2× 4 + 1× 5 (how many numbers) and rather than count how many numbers there are, we can add up the frequencies: 2060 + 30f1 + 70f2 = 62.8 (50) 2060 + 30f 1 + 70f 2 = 3140. So, we have, x+y=30 we can find the other equation by equating the mean value by sum of (fm/m) then solve the 2 equations for x and y Σf = 5 + f1 + 10 + f2 + 7 + 8. I hope it was helpful, you can refer to more posts related to the statistics. After finding missing frequency determine standard deviation and coefficient of vari. Ation show your whole working for this question and i am warning: Mean = 2 + 10 + 12 + 8 + 5 14 = 3714 = 2.64.

Σf = 5 + f1 + 10 + f2 + 7 + 8. Σfx = 2060 + 30f 1 + 70f 2. Use the formula (# +#)/2=median and solve. If it is, you can take the median and the one of the two numbers you know. ← prev question next question →. To make these videos i use following products. Σf = 30 + f 1 + f 2. Only mathdude500 will answer no one will give answer show your whole working for 4th quest. Σf = 5 + f1 + 10 + f2 + 7 + 8. Aboat goes downstream from one part of the river to another part of river in 16 hours it covers the same distance upstream in 20 hours if the speed of stream is 2 km per hour find. We have a median, lower limit.
