Answer: Using the information of the conditional relative frequency table, 123 students in the survey said that math was their favorite subject.
Solution:
1. The survey was given to 120 male students.
Acconding with the table, the proportion of male students with Math as favorite subject is 0.35. The quantity of male students with Math as favorite subject would be:
0.35(120)=42 male students
2. The survey was given to 180 female students.
Acconding with the table, the proportion of female students with Math as favorite subject is 0.45. The quantity of female students with Math as favorite subject would be:
0.45(180)=81 female students
Then the total of students in the survey said that math was their favorite subject would be:
42 male students + 81 female students = 123 students
Answer:
C) 2 + 3 x - 18
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given expression 2+ 3(x-6)
⇒ 2 + 3 x - 18
⇒ 3 x - 16
Find range ,median mode and mean of the following numbers -19,-11,-19,-18,-13,-19,-18,-11.0, 11,12

Range= 31 because 12- -19 = 31 you subtract the lowest with the highest.
Mean= 8.3
Mode = -19 because you mostly see -19 there’s 3 -19 . :)))
