Answer:
The number of movies purchased is 5
Step-by-step explanation:
40.00 + 3.50 = 43.50
43.50 + 3.50 = 47.00
47.00 + 3.50 = 50.50
50.50 + 3.50 = 54.00
54.00 + 3.50 = 57.50
so if you add 3.50 to 40, 5 times you'll get 57.50
Hope it helped
C/a is the amount they bought so it would be 0.99*c or .99 times the amount they bought same goes to .79a
Answer: The required probability is 0.1923.
Step-by-step explanation:
Since we have given that
Probability that it's a good dog = 0.4
Probability that it's a bad dog = 1-0.4 = 0.6
Probability that the dog smokes given that its a bad dog = 0.7
Probability that it smokes given that its a good dog = 0.25
According to question, probability of smoking pipe would be
P(good).P(Smoking pipe|good)+P(bad).P(smoking pipe|bad)
![0.4\times 0.25+0.6\times 0.7\\\\=0.1+0.42\\\\=0.52](https://tex.z-dn.net/?f=0.4%5Ctimes%200.25%2B0.6%5Ctimes%200.7%5C%5C%5C%5C%3D0.1%2B0.42%5C%5C%5C%5C%3D0.52)
So, Probability of getting a good dog given that it is smoking pipe is given by
![\dfrac{P(good).P(smoking\ pipe|good)}{P(smoking\ pipe)}\\\\=\dfrac{0.4\times 0.25}{0.52}\\\\=\dfrac{0.1}{0.52}\\\\=0.1923](https://tex.z-dn.net/?f=%5Cdfrac%7BP%28good%29.P%28smoking%5C%20pipe%7Cgood%29%7D%7BP%28smoking%5C%20pipe%29%7D%5C%5C%5C%5C%3D%5Cdfrac%7B0.4%5Ctimes%200.25%7D%7B0.52%7D%5C%5C%5C%5C%3D%5Cdfrac%7B0.1%7D%7B0.52%7D%5C%5C%5C%5C%3D0.1923)
Hence, the required probability is 0.1923.
Answer:
x = 69
Step-by-step explanation:
The sum of the angles round a point is 360°
Subtract the sum of the 2 given angles from 360 for x
x = 360 - (168 + 123) = 360 - 291 = 69
