Answer:
6.5 x 10^-7
Step-by-step explanation:
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>
La respuesta es 112, es una regla de tres simples
11w times 6x
240w times 18y
you always use the last numbers and that would equal...
____________________________________________________________
66x times 4320y=
285120 divide it by 6= 47520
then by 12
47520 divided by 12=
3960-80= 3880
3880 divided by 16 times 4
your answer is 970y
Answer:
X^2-18x+81
OR
(X-9)^2
Step-by-step explanation:
X(x-9)-9(x-9)=
x^2-9x-9x+81
X^2-18x+81
