Question 4 is Choice A
Question 5 is Choice B
Question 6 is Choice C
Question 7 is Choice B
These are relatively simple it’s just understanding the relations of x and y values :)
In the study the total number of males was 739 and the total number of all employees was 1501. The men who felt stressed or tensed out during work were 244 and those that never felt stressed out were 495.
Assuming that, A= Employed adults was male and B= Employed adult felt tense or stress out at work.
Then , P(A/B) = P(A∩B)/ P(B)
P(B) is the probability of having a male.
P(B) = 739/1501
P(A∩B) is the probability of a man being stressed or tensed out at work.
and P(A∩B) = 244/ 1501
Hence, P(A/B) =(244/1501)/ (739/1501)
= 244/739
= 0.3302.
Thus, the probability that the employed work felt tense or stress at work given that the employed employee was male is 0.3302

The given problem is a quadrilateral shape. There are 4 angles and sides shown in the problem and the only given angle is X.
The illustration shows four sides (quad), the stick drawn at the center of each sides describes the relationship of their lengths.
All one stick are equal, and two sticks are also equal.
Given Angles:
X=102 deg
W=(7x+4) deg
Y=(5x-4) deg
Since angle X is 102 degrees, then angle Z is also 102 degrees. The total angle of a quadrilateral is 360 degrees.
So, to find x:
102 + 102 + 7x + 4 + 5x - 4 = 360
x=13
