Answer:
For The value of a = 0 and c = 0 , The given expression equality is true
Step-by-step explanation:
Given expression as :
= a - 2
Or, 3 a² + ac + 2 c - 6 a = ( a - 2 ) × ( 3 a - c )
Or, 3 a² + ac + 2 c - 6 a = 3 a² - ac - 6 a + 2 c
Or, ( 3 a² + ac + 2 c - 6 a ) - ( 3 a² - ac - 6 a + 2 c ) =0
Or, ( 3 a² - 3 a² ) + ( ac + ac ) + ( 2 c - 2 c ) + ( - 6 a + 6 a ) = 0
or, 0 + 2 ac + 0
Or, 2 ac = 0
∴ a =0 and c = 0
Hence For The value of a = 0 and c = 0 , The given expression equality is true . Answer
Answer:
Mean deviation of 80, 88, 93, 95 is 5
Step-by-step explanation:
Step 1: find the mean
Mean = Sum of items/ Number of items
Mean = 80+88+93+95 = 356
Mean = 356 / 4 = 89
Step 2: find the mean deviation
Mean Deviation = ∑i = 0n |xi − μ| / N
Mean Deviation = | (89-80) + (89-88) + (89-93) + (89-95) | /4
Mean Deviation = 5
