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:
A) (7.6, 8.8)
which are the coordinates of the treasure.
Missing Problem Statement:
Given Options:
A) (11.4, 14.2)
B) (7.6, 8.8)
C) (5.7, 7.5)
D) (10.2, 12.6)
I have added the picture showing the traced map onto a coordinate plane to find exact location of treasure.
The coordinates of Tree are (16,21)
Coordinates of rock are (3,2)
Step-by-step explanation:
Let,
Coordinates of treasure be (a,b)
= distance from tree to treasure
=distance from rock to treasure
Given ratio between rock and tree, = 0.55_______(Equation.1)
which will be used to locate the treasure.
Now we just need to cross check by putting the coordinates given in the options one by one to find out value of ,
and checking if it satisfies the Equation 1.
Check (A) (11.4, 14.2)
= 14.8,
= 8.2,
= 1.8
Check (C) (5.7, 7.5)
= 6.13,
= 16.98,
= 0.36
Check (D) (10.2, 12.6)
= 12.8,
= 10.2,
= 1.25
Check (B) (7.6, 8.8)
= 8.2,
= 14.8,
= 0.55
Which satisfies Equation 1, such that ratio between rock and tree is 5:9 or = 0.55
So, the coordinates of the treasure are (B) (7.6, 8.8)
