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:
12/25
Step-by-step explanation:
multiply the fractions.
multiply the numbers.
7x8=56 (area of the rectangle of the “house” shape)
11-8=3
7x3=21x1/2 (how to find area of the triangle)
10.5
So the answer is 10.5 cm2 (centimeters squared)
Answer:
B, 118°
Step-by-step explanation:
The sum of angles on a straight line is 180° (because the measure of a straight line is 180°)
Thus:
m∠RSU + m∠UST = 180°
Substitute m∠UST with 62°.
m∠RSU + 62° = 180°
Subtract both sides by 62°.
m∠RSU = 118°
So, the answer is B, 118°
