Given that X <span>be the number of subjects who test positive for the disease out of the 30 healthy subjects used for the test.
The probability of success, i.e. the probability that a healthy subject tests positive is given as 2% = 0.02
Part A:
</span><span>The probability that all 30 subjects will appropriately test as not being infected, that is the probability that none of the healthy subjects will test positive is given by:
</span>
<span>
Part B:
The mean of a binomial distribution is given by
</span>
<span>
The standard deviation is given by:
</span>
<span>
Part C:
This test will not be a trusted test in the field of medicine as it has a standard deviation higher than the mean. The testing method will not be consistent in determining the infection of hepatitis.</span>
D. 100/135 the rest of them equal 135%
Answer:
84
Step-by-step explanation:
women=x
daughter=y.
x=2y.
x-21=3(y-21).
2y-21=3y-63.
42=y.
x=84.
Hope this helps plz hit the crown :D
Answer:
The slope of the line is and the equation of the line is .
Step-by-step explanation:
From table we understand that slope of the line is constant, that is, for each change of there is one and only change in , fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:
(1)
Where:
- Initial and final x-coordinates of the line.
- Initial and final y-coordinates of the line.
If we know that and , then the slope of the line is:
From graph we conclude that x-intercept of the line is . Hence, the equation of the line is and we proceed to plot the expression with the help of a graphing tool.
