Consider the following table with information about a sample of students from GCA and if they had trigonometry before taking AMD
M. If a person is randomly selected determine the following probability provided the conditions: P(Trig|Male)
2/11
1/6
11/24
1/3
2/11
1/6
11/24
1/3
1 answer:
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:
Perimeter = 32.3
Area = 95.24
Step-by-step explanation:
Given:
△ABC, m∠A=60°
m∠C=45°, AB = 9
To find:
Perimeter of △ABC
Area of △ABC
Solution:
Using angle sum property in a triangle:
m∠A + m∠B + m∠C = 180°
m∠B = 180° - 45° - 60° = 75°
As per Sine Rule:
Where
is the side opposite to
is the side opposite to
is the side opposite to
Perimeter of △ABC = AB + BC + AC = 9 + 11.08 + 12.22 = <em>32.3</em>

Area of a triangle is given as:
