Answer:
Correct option: (a) 0.1452
Step-by-step explanation:
The new test designed for detecting TB is being analysed.
Denote the events as follows:
<em>D</em> = a person has the disease
<em>X</em> = the test is positive.
The information provided is:
Compute the probability that a person does not have the disease as follows:
The probability of a person not having the disease is 0.12.
Compute the probability that a randomly selected person is tested negative but does have the disease as follows:
Compute the probability that a randomly selected person is tested negative but does not have the disease as follows:
Compute the probability that a randomly selected person is tested negative as follows:
Thus, the probability of the test indicating that the person does not have the disease is 0.1452.
Answer:
5 blocks south and 4 blocks west
Step-by-step explanation:
Answer:
AB = 4.73
Step-by-step explanation:
Given BC = 2 and A = 25
°
To find AB we have to use sin function in trig equation:
sin A = BC/AB
sin 25° = 2/AB
Multiply both sides by AB
AB x sin 25° = 2
AB x 0.42 = 2
Dividing the equation by 0.42
AB = 4.73
To find the x intercept, set y = 0. To find the y intercept set X = 0.
X intercept: 0 = 2/3x + 6 and then solve for x.
Y intercept: y = 2/3 (0) + 6 and then solve for y.
You divide by 2 until you can't divide by 2 anymore.
Hope this helps.
