8
Correct answer is B
6, p, 14
14 - p = p - 6
14 + 6 = p - 6
14 + 6 = p + p
2p2
= 202
p = 10
If 23y = 1111two, find the value of y

Correct answer is C
23y = 1111two,
2 x y1 + 3 x y0 = 1 x 23 + 1 x 21 + 1 x 2o
2y + 3 = 8 + 4 + 2 + 1
2y + 3 = 15

{1, 2, 3, 5, 7, 8, 9}
Correct answer is A
T = {2, 3, 5, 7}
M = {1, 3, 5, 7, 9}
μ = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
T′ = = {1, 4, 6, 8, 9, 10}
M′ = {2, 4, 6, 8, 10}
(T′ ∩ M′) = {4, 6, 8, 10}
