Answer:
The correct option is 4.
Step-by-step explanation:
Given information:
Bring lunch : 46 males, 254 females
Buy lunch : 176 males, 264 females
Total number of peoples is

Total number of males is

The probability of male is

Since probability of males is 0.3, therefore options A and C are incorrect.
Total number of persons who buys lunch is

The probability of persons who buys lunch is

We need to find the probability of P(male | buys lunch).
According to the conditional probability, we get

P(male | buys lunch)
P(male | buys lunch)
P(male | buys lunch)
Therefore the correct option is 4.
Answer:
see explanation
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Summing the 3 angles and equating to 180 gives
2x + 3 + 4x + 2 + 2x - 1 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
∠A = 2x + 3 = (2 × 22) + 3 = 44 + 3 = 47°
∠B = 4x + 2 = (4 × 22) + 2 = 88 + 2 = 90°
∠C = 2x - 1 = (2 × 22) - 1 = 44 - 1 = 43°
15. 6x + 12
16. 12y - 4
17. - 15p - 21
18. 24 - 8x
19. 7 - 42c
20. -20 + 15y
21. 3(x + 4)
22. 5(3 - 2k)
23. 3(3a + 5)
24. - 2(10 + 3b)
25. B) 4(2n - 5)
26. D) 8(3 - 2r)
