Answer:
0.1562 = 15.62% probability that a person who tests positive actually has the disease.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Tests positive
Event B: Has the disease.
Probability of a positive test:
100 - 8 = 92% of 0.6%(person has the disease).
3% of 100 - 0.6% = 99.40%(person does not have the disease). So
Probability of testing positive and having the disease:
92% of 0.6%. So
Probability that a person who tests positive actually has the disease.
0.1562 = 15.62% probability that a person who tests positive actually has the disease.
Answer:
a² + b² = c²
Step-by-step explanation:
The sum of the legs squared is equal to the hypotenuse squared.
a² + b² = c²
Where a and b are legs.
c is the hypotenuse.
Yes a negative x a negative ( eg -2 x -3 ) = a positive ( eg 6 )
From the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.
The leading cause of train derailment will be the cause on the pie-chart that has the largest sector.
From the pie-chart given, the largest sector in the diagram is the sector for "Human Error."
This means that the leading cause is definitely "Human Error."
The central angle of the sector for "Human Error." is between 90 degrees and 180 degrees. That's less than half a full circle and less of a quarter circle. The best estimate from the given options is <u>165 degrees.</u>
Therefore, from the pie-chart given, the best estimate for central angle for the leading cause which is "Human Error" is: B. 165 degrees.
