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.
The answer is $340. If this helps please give me brainliest answer, I would appreciate it! :)
4.75×6=28.5
6 cookies= 6x
The expression is 6x+28.5
Hello there! Your answer would be: the total bill was was $114.
Okay, so to solve this multiply the individual person's amount by the number of people there. Note that the equation says "Jacob and 5 friends" indicating that Jacob is one of these people, and there are 5 others, so we have 6 in total.
$19 x 6 = $114
So, the total bill was was $114. I hope this helped, and have a great rest of your day! :)
