Answer:
Probability that a person actually has the disease given that the test indicates the presence of the disease is 0.657.
Step-by-step explanation:
We are given that a blood test indicates the presence of a particular disease 95% of the time when the disease is actually present.
The same test indicates the presence of the disease 0.5% of the time when the disease is not actually present. One percent of the population actually has the disease.
Let the Probability that person actually has the disease = P(A) = 0.01
Probability that person actually doesn't has the disease = P(A') = 1 - P(A) = 1 - 0.01 = 0.99
Also, let PD = event that there is a presence of the disease
So, Probability that test indicates the presence of the disease given the fact that the disease is actually present = P(PD/A) = 0.95
Probability that test indicates the presence of the disease given the fact that the disease is not actually present = P(PD/A') = 0.005
Now, the probability that a person actually has the disease given that the test indicates the presence of the disease = P(A/PD)
We will use Bayes' theorem to calculate the above probability.
SO, P(A/PD) =
=
= = 0.657
Hence, the required probability is 0.657.
If a single board measures 1/12 of a meter then it would take 12 boards to make a meter. Since, the stack is 2 meters high. You would multiply 12 and 2 to get 24. There is 24 boards in the stack.
Answer:
The Amount after 4 years is $2430 .
Step-by-step explanation:
Given as :
The principal amount investment = p = $2000
The rate of interest applied = r = 5%
The time for investment = t years
Let The Amount after t years = $A
<u>From Compound Interest method</u>
Amount = Principal ×
Or, A = p ×
Or, A = $2000 ×
Or, A = $2000 ×
So, The Amount after t years = A = $2000 ×
B) The principal amount investment = p = $2000
The rate of interest applied = r = 5%
The time for investment = t = 4 years
Let The Amount after t years = $A
<u>From Compound Interest method</u>
Amount = Principal ×
Or, A = p ×
Or, A = $2000 ×
Or, A = $2000 ×
i.e A = $2000 × 1.215
Or, A = $2430
So, The Amount after 4 years = A = $2430
Hence, The Amount after 4 years is $2430 . Answer
Answer:
Place the ruler such that the edge is against the object. Parallax is a distortion of view because humans see through two sources, not just one. the farther the object is away from the ruler, the more that parallax can affect the situation.
