Answer: The answer is 30%.
Step-by-step explanation: Given that there is a group of 10 light users and 10 heavy users. We are to find the probability that exactly 3 of the 20 users are HIV positive.
We have the following four possible cases -
(i) All 3 are light users.
(ii) 1 is a light user and 2 are heavy users.
(iii) 2 are light users and 1 is a heavy user.
(iv) All 3 are heavy user.
Since there is a 45% chance of a light user to be HIV positive and 55% chance of a heavy user to be HIV positive, so the required probability is given by
Thus, the probability is 30.
Answer:
And the answer for this case would be :
after round the value
Step-by-step explanation:
We have the following data set given:
31, 33, 36, 41, 34
If we want to find the standard deviation we need to find first the sample mean with this formula:
And replacing we got:
Now we can find the sampel deviation with this formula:
And replacing we got:
And the answer for this case would be :
after round the value
Answer:
Quadrant IV
Step-by-step explanation:
Quadrant I = (+ , +)
Quadrant II = (- , +)
Quadrant III = (- , -)
Quadrant IV = (+ , -)
(1/2 , -1.8)
1/2 is +
1.8 is -
(+ , -)
It lies on Quadrant IV
