Tutorial Question A survey of consumer profile of 3 commodities, A, B & C
among 140 consumers revealed the following conditions:
14 patronise B only
39 patronise C only
9 patronise A & C but B
14 patronise A & B
82 patronise either B or C or both but not A
60 patronise either A or B or both but not C
Calculate:
(i) The number of consumers who patronize all the
products
The number of those who patronize at least 2 products
(111) The number of those who patronize one product.
(ii)​

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
