Answer:
x= √10/2
Step-by-step explanation:
if you use trig. functions:
sin 45° = opposite side /hypothenuse = x/√5
sin 45° = √2/ 2
√2/2 = x/√5 multiply both sides by √5
x= (√2*√5)/2 = √10/2
if you use that is a 45-45-90 special triangle
the sides are x, and hypothenuse must be x√2 in this type of triangles so in our case:
x√2 = √5 divide both sides by √2
x= √5/√2 multiply by √2/√2 which =1 and help us get rid of the radical from the denominator
x= (√5*√2)/ (√2*√2) = √10/2
Answer:
a) 0.9548
b) 0.0452
Step-by-step explanation:
Specificity of test:
The specificity of a test is the true negative rate, that is, the proportion of people without the disease that test negative.
Sensitivity of test:
The sensitivity of a test is the true positive rate, which is the proportion of people with the disease that test positive.
a. What proportion of the people who test positive for Malaria would we expect to actually have the disease?
This is the sensitivity of the test, which is of 95.48%, so the proportion if 0.9548.
b. What proportion of people who test positive for Malaria will not have the disease?
True positive rate is of 95.48%.
1 - 0.9548 = 0.0452
So the proportion of people who test positive for Malaria will not have the disease is 0.0452.
