Answer:
Step-by-step explanation:
The conditional probability P(W|X) means "Probability of W happening GIVEN THAT X has happened".
We want to find P(Trig|Male). This would mean, we want people who are male...then we look, how many of them took Trig.
Looking at the table, row and column of Trig & Male is "8".
Hence, Probability would be 8/48 [48 is the total number of people, given in right bottom most part of the table]
8/48 = 1/6
Correct answer is 2nd option, 1/6
Answer: it is a solution set
Step-by-step explanation:
The given system of simultaneous linear equations is expressed as
7x-3y=6 - - - - - - - - - -1
2x+y=11 - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 7. It becomes
14x - 6y = 12
14x + 7y = 77
Subtracting, it becomes
- 13y = - 65
Dividing the left hand side and the right hand side of the equation by - 13, it becomes
- 13y/13 = - 65/- 13
y = 5
Substituting x = 5 into equation 2, it becomes
2x + 5 = 11
Subtracting 5 from the left hand side and the right hand side of the equation, it becomes
2x + 5 - 5 = 11 - 5
2x = 6
Dividing the left hand side and the right hand side of the equation by 2, it becomes
x = 6/2 = 3
For section 1.....Problem a is 7.2 Problem B is 7.6 Problem C is 18.8 Problem E is 32.5 Problem F is 28.8 Problem G is 10 Problem I is 61.5 Problem J is 170.8 Problem K is 81.6.
For Section 2 Problem A is 9.36 Problem B is 10.35 Problem C is 25.85 Problem E is 1.82 Problem F is 3.28 Problem G is 2.8 Problem I is 42.21 Problem J is 56.16 Problem K is 7.65
You can use this ratio:
1hour/60minutes=0.73hours/Xminutes
and cross multiply
so x= 43.8 minutes
