The surface area would be 166.
In a parallelogram, opposite sides have the same length.
3x + 9 = 5x -5
group like terms on one side
9 + 5 = 5x -3x
14 = 2x
x is 7.
Since AB is 5x -5
AB = 5(7) -5
AB = 30.
BX is half of the line DB. So BX = DX
5y = 7y - 10
10 = 7y -5y
10 = 2y
y =5.
Since BX = 7y - 10
BX = 7(5) -10
BX = 25

Step-by-step explanation:
Answer:
(a) 0.139258
(b) 0.0064827
Step-by-step explanation:
Let the probability that each member makes a correct decision be and the probability that each member makes an incorrect decision be .
From the question,
p and q are mutually exclusive. Hence,
(a) For majority rule, it means at least 4 members decisions are taken. Taking "C" to mean "correct" and "I" to mean "incorrect", we could have 4C against 3I, 5C against 2I, 6C against 1I and 7C against 0I.
The probability of the correct decision being made is
(b)
