Answer:
length = 9 units
Step-by-step explanation:
l = length
n - 6 = width
A = n(n - 6)
A = n² - 6n
27 = n² - 6n
n² - 6n - 27 = 0
(n + 3)(n - 9) = 0
n = -3, n = 9
length must be 9 because it cannot be a negative value
Answer:
0.1552
Step-by-step explanation:
Hi!
Give a random person, lets call:
D = the person has the disease
¬D = the person doesnt have the disease
T = the test on this person is positive (detects the disease)
¬T = the test on this person is negative
We are give the conditional probabilities:
P(T | D) = 0.9
P(¬T | ¬D) = 0.9
P(D) = 0.02
From those we know that:
P(T | ¬D) = 0.1
P(¬T | D) = 0.1
We must find P(D | T). For that we use Bayes theorem:
