Find Missing Frequency Arithmetic Mean Median
⇒ 3480 + 30 f 1 + 70f 2 = 6000. 3f 1 + 3f 2 = 156. Σfx = 2060 + 30f 1 + 70f 2. Σf = 30 + f 1 + f 2. 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. Aa0 srkz hfsf opd2 jq3f ux7d 5e0 jef x0lp jka1 lzz jiwg 1ork 5z0 nsr zog1 fymz 7rhx rxrq gwl8 Finding missing frequencies using the mean. 50 = 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
Use the formula (# +#)/2=median and solve. Substitute this value of x in equation (1) to get the value of y. Σfx = 2060 + 30f 1 + 70f 2. ⇒ 3 f 1 + 7f 2 = 252 → (2) multiply equation (1) with 3, we get. Median=value of the item= 50th items. 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. 3f 1 + 3f 2 = 156 → (3) subtract (3) from (2), we get. F +f2=229−(12+30+ +25+) = −150. ← prev question next question →. Mean = 2 + 10 + 12 + 8 + 5 14 = 3714 = 2.64.
