The probability that Andrew has heart disease is 0.9. Andrew takes a test for the disease that has an accuracy rate of 75%. What is the probability that Andrew has heart disease and the test accurately predicts it?
Answer: The probability that Andrew has heart disease
Also we know that the accuracy rate of test or
The given two events are independent.
Therefore, the probability that Andrew has heart disease and the test accurately predicts it
11). X1= 1/4 and X2=7
12). X1=-4/3 and X2= 7/3
If you are taking the cm to km then it would be like this
4.5km*4.1cm= 18.45km
Answer:
(f - g)(-4) = 17
Step-by-step explanation:
To get (f - g)(x), you need to subtract f(x) with g(x).
f(x) = 2x² + 2
g(x) = -3x + 5
(f - g)(x) = (2x² + 2) - (-3x + 5)
(f - g)(x) = 2x² + 2 + 3x - 5
(f - g)(x) = 2x² + 3x - 3
Now, plug in -4 to find (f - g)(-4).
(f - g)(x) = 2x² + 3x - 3
(f - g)(-4) = 2(-4)² + 3(-4) - 3
(f - g)(-4) = 2(16) + 3(-4) - 3
(f - g)(4) = 32 - 12 - 3
(f - g)(-4) = 17
