The probabilities of a test are represented by I for infected; U, uninfected; D, infection detected; and N, no infection detected. What is the symbolic way to represent the probability of a true positive? P(I⋂D) P(I⋂D)P(D) P(U⋂N)P(N) P(I⋃D)

Answers

Answer 1
Answer:

Answer:

The symbolic way to represent the probability of a true positive is:

               P(I∩D)

Step-by-step explanation:

The representation is given as follows:

I for infected; U, uninfected; D, infection detected; and N, no infection detected.

We are asked to find which expression represents the probability of a true positive.

i.e we are asked to find the probability that a person who is infected is also detected.

Let P denote the probability of an event.

        Hence, the expression is:

           P(I∩D)
Answer 2
Answer: \mathbb P(I\cap D)

Damari inflates a spherical balloon to twice its original radius. Explain to Damari why the surface area is 4 Tims as big when the radius is doubled.

Answers

The easiest way is to show him the formula for the area of a sphere:

Area = 4 π (radius)²

That's a good thing to discuss, because it's a good thing to remember,
and discussing it will help him remember it.

The important part to look at is the part where it says " (radius)² " .
That tells you that if you multiply the radius by (Anything), then
the area is multiplied by (Anything)² .

Since he multiplied the radius by 2, the area was multiplied by (2)² = 4 .
Surface area is directly proportional to the square of radius.

Thus, when radius is doubled, Surface area becomes 2² = 4 times.

A circular track has a circumference of 1/4 mile. What is the radius?

Answers

The formula for circumference is C = 2 \pi r. We know the circumference and therefore we can plug that into the formula and solve for the radius.

(1)/(4) = 2 \pi r

Lets divide by 2 first.
(1)/(8)= \pi r

Next, lets divide by pi.
(1)/(8 \pi)= r
Thus the answer is (1)/(8 \pi) of a mile, which is approximately (1)/(25.13) of a mile.
