Answer:

B. is exactly 1 triangle

Step-by-step explanation:

For any given triangle, the sum of the internal angles is 180^{o}. Thus from the given question, adding the given angles;

30° + 70° + 80° = 180^{o}

Therefore, only one triangle can be produced with the given measure of angles. This implies that there is exactly one triangle. So that the correct option is B.

From experience, an airline knows that only 80% of the passengers booked for a certain flight actually show up. If 9 passengers
Olenka [21]

Answer:  0.74

Step-by-step explanation:

Given : The probability that the passengers booked for a certain flight actually show up : p=0.80

The number of passengers are randomly selected : n= 9

Binomial probability formula to find the probability of getting success in x trial :-

P(x)=^nC_xp^x(1-p)^{n-x}

Then , the probability that more than 6 of them show up will be :-

P(x>6)=P(7)+P(8)+P(9)\\\\=^9C_7(0.8)^7(0.2)^{2}+^9C_8(0.8)^8(0.2)^{1}+^9C_9(0.8)^9(0.2)^{0}\\\\=\dfrac{9!}{7!(9-7)!}(0.8)^7(0.2)^{2}+(9)(0.8)^8(0.2)+(1)(0.8)^9\approx0.3020+0.3020+0.1342=0.7382\approx0.74

Hence, the probability that more than 6 of them show up = 0.74
