Answer:
15.6
Step-by-step explanation:
the angle = 180-61-42=77°
x = 14.sin 77/sin 61
= 14×0.97/0.87
= 15.6
7 x 10x10x10 = 7000 third power only means the number of 10's so
Answer:
- p(12 are truthful) ≈ 0.0687
- p(≥ 1 are not) ≈ 0.9313
Step-by-step explanation:
The probability the test says 1 is truthful is 0.8, so the probability that all 12 will be judged truthful is ...
0.8^12 ≈ 0.0687
The probability that at least one will be judged untruthful is the complement of this:
1 - 0.0687 = 0.9313
The probability that the lie detector says all 12 are truthful is about 0.0687.
The probability that lie detector says at least 1 is deceptive is about 0.9313.
Answer:
- The graph cannot represent a normal density function because it is not symmetric.
Step-by-step explanation:
The second and third descriptions are false on their face: neither describes a characteristic of the graph shown. A normal distribution is symmetric about the mean; this graph is not symmetric, so cannot represent a normal distribution.
The value of y, when solving the equation appears to be 3/4 when setting up and solving the equation.
I hope this helps, have a great day, and God bless.
