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
You need to use pemdas here to understand order of operations. So you need to multiply the 8 by the 4 to give 32, then add 4 to get 36. And now you can take the 32 and divide. So you get 36/32 or 9/8
Answer:
X = 10
Step-by-step explanation:
First you subtract -X from 3x to get 2x +3 =23
then you subtract 3 from both sides to get 2x = 20
then finally, you divide both sides by two to get x = 10
And if you plug 10 back in you get -10 + 3 + 30 = 23
-10 + 3 = -7
-7 + 30=23
23=23
Answer:
x + x+1 + x+2 + x+3 + x+4 + x+5 + x+6 =217
7x+21=217
7x=196
x=28
Middle Number will be:
x+3
28+3
=31
Therefore, the middle number is 31.
