Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
0.0713 = 7.13% probability that the result is positive.
The values of y are 7, 8.5, 10.5 and 11
<h3>How to determine the values of y?</h3>
The equation is given as:
y = 1/2x + 5
The domain is given as:
Domain = 4, 7, 11, 12
This means that
x = 4, 7, 11, 12
Substitute x = 4, 7, 11, 12 in the equation y = 1/2x + 5
So, we have:
y = 1/2 * 4 + 5 = 7
y = 1/2 * 7 + 5 = 8.5
y = 1/2 * 11 + 5 = 10.5
y = 1/2 * 12 + 5 = 11
Hence, the values of y are 7, 8.5, 10.5 and 11

Answer:
The pre-image is the point (0,11)
Step-by-step explanation:
we know that
The rule of the translation is equal to
pre-mage------> image
(x,y) -----> (x+1,y-4)
so
we have that
(x+1,y-4)=(1,7)
so
x+1=1 -----> x=1-1=0
y-4=7 ----> y=7+4=11
therefore
The pre-image is the point (0,11)
