Answer:
SA = 2280 cm²
Step-by-step explanation:
bottom & top = 40 x 12 x 0.5 x 2 = 480
sides = (13x20) + (40)(20) + (37)(20) = 1800
1800 + 480 = 2280 cm²
A
The absolute value of -27 is 27, so it is the same number
Answer:
8% probability that he or she actually has the disease
Step-by-step explanation:
We use the Bayes Theorem to solve this question.
Bayes Theorem:
Two events, A and B.
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
If a randomly chosen person is given the test and the test comes back positive for conditionitis, what is the probability that he or she actually has the disease?
This means that:
Event A: Test comes back positive.
Event B: Having the disease.
Test coming back positive:
2% have the disease(meaning that P(B) = 0.02), and for those, the test comes positive 98% of the time. This means that
For the 100-2 = 98% who do not have the disease, the test comes back positive 100-77 = 23% of the time.
Then
Finally:
8% probability that he or she actually has the disease
Heres a tip, multiply the numbers without any decimals then when done, add how many decimal places there are in total.
Ex:16.28 x 4 = 65.12
1625 x 4 = 6512
