Is 4 hours greater or less than 14,400 seconds? (Or equal too)

DochEvi [55]

Answer:

Equal to.

Step-by-step explanation:

The easiest way to figure this out is to convert 14,400 seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour. So, divide 14,400/60, which is 240. This is now 240 minutes. To figure out minutes into hours, divide 240/60, which is 4. 4=4, so 4 hours equals 14,400 seconds.

Leto [7]

Answer:

The probability that the diagnosis is correct is 0.95249.

Step-by-step explanation:

We are given that the American Diabetes Association estimates that 8.3% of people in the United States have diabetes.

Suppose that a medical lab has developed a simple diagnostic test for diabetes that is 98% accurate for people who have the disease and 95% accurate for people who do not have it.

Let the probability that people in the United States have diabetes = P(D) = 0.083.

So, the probability that people in the United States do not have diabetes = P(D') = 1 - P(D) = 1 - 0.083 = 0.917

Also, let A = event that the diagnostic test is accurate

So, the probability that a simple diagnostic test for diabetes is accurate for people who have the disease = P(A/D) = 0.98

And the probability that a simple diagnostic test for diabetes is accurate for people who do not have the disease = P(A/D') = 0.95

Now, the probability that the diagnosis is correct is given by;

Probability = P(D) $\times$ P(A/D) + P(D') $\times$ P(A/D')
