Mathematics
1 answer:
UkoKoshka [18]2 years ago
5 0

Answer:

38. <1 = 38^{o}, <2 = 32^{o}, <3 = 110^{o}

39. <1 = 71^{o}, <2 = 28^{o}, and <3 = 81^{o}

Step-by-step explanation:

38. Sum of angles in a triangle = 180^{o}

So that;

38 + 110 + <2 = 180^{o}

148 + <2 = 180^{o}

<2 = 180^{o} - 148

<2 = 32^{o}

Thus,

<1 = 38^{o} (alternate angle principle)

<3 = 110^{o}

Therefore;

<1 = 38^{o}, <2 = 32^{o}, <3 = 110^{o}

39. <2 = 28^{o} (alternate angle principle)

So that;

sum of angles in a triangle = 180^{o}

<1 + <2 + 81 = 180^{o}

<1 + 28^{o} + 81 = 180^{o}

<1 + 109 = 180^{o}

<1 = 180^{o} - 109

   = 71^{o}

<1 = 71^{o}

<3 = 81^{o}

<1 = 71^{o}, <2 = 28^{o}, and <3 = 81^{o}

Consider the random experiment of tossing 3 fair coins and observing how many of them come to rest with the heads side of the co
zaharov [31]

Answer:

b. S = AUB

Step-by-step explanation:

Since the coins are tossed  3 times and each coin has head, H and tail, T(2 sides), the sample space is S = 2 × 2 × 2 = 2³ = 8

All the possible outcomes are HTT, HHT, HHH, THH, TTH, HTH,THT and TTT

Since S denote the sample space

S = {HTT, HHT, HHH, THH, TTH, HTH,THT, TTT}

Since A denote the event that at least 1 of the coins comes to rest with its heads side upwards, the possible outcomes are HTT, HHT, HHH, THH, TTH, HTH and THT

So, A = {HTT, HHT, HHH, THH, TTH, HTH,THT}

Also B denote the event that none of the coins comes to rest with its heads side upwards, that is no heads. The possible outcome is TTT

So, B = {TTT}

Since S denote the sample space

S = {HTT, HHT, HHH, THH, TTH, HTH,THT, TTT}

So, A ∪ B = {HTT, HHT, HHH, THH, TTH, HTH,THT} ∪  {TTT} = {HTT, HHT, HHH, THH, TTH, HTH,THT, TTT} = S

So, S = A ∪ B

So, S = A ∪ B does not denote an abuse of notation.

The answer is b.
