3 Mean (two missing frequencies and mode) hindi Explanation YouTube
50 = 30 + f 1 + f 2. Aa0 srkz hfsf opd2 jq3f ux7d 5e0 jef x0lp jka1 lzz jiwg 1ork 5z0 nsr zog1 fymz 7rhx rxrq gwl8 Median=value of the item= 50th items. Σf = 30 + f 1 + f 2. 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 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. Mean = 2 + 10 + 12 + 8 + 5 14 = 3714 = 2.64. Only mathdude500 will answer no one will give answer show your whole working for 4th quest. Calculate the missing frequency from the following distribution,. To make these videos i use following products.
A student noted the number of cars passing through a spot on a road for 100 periods each of 3 minutes and summarized it in the table given below. If it is, you can take the median and the one of the two numbers you know. 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. Median=value of the item= 50th items. Σfx = 2060 + 30f 1 + 70f 2. After finding missing frequency determine standard deviation and coefficient of vari. So, missing frequency is 15. ⇒ 3480 + 30 f 1 + 70f 2 = 6000. 50 = 30 + f 1 + f 2. 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.
