students that own a cell phone but don't own an MP3: 78 - 57 = 21
total number of student with no cell phone: 13 + 9 = 22
total number of student with a MP3 player: 57 + 13 = 70
total number of student without a MP3 player: 21 + 9 = 30
total number of students: 70 + 30 = 78 + 22 = 100
MP3 player no MP3 player Total
cell phone 57 21 78
no cell phone 13 9 22
Total 70 30 100
Answer:
1. Y≤2x-4
2. Yes, since its a solid line it includes points on the line
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Compare the coordinates of corresponding vertices.
C(7, - 2 ) → C'(- 3, 7 )
x- direction 7 → - 3 , that is - 10 of a shift
y- direction - 2 → 7, that is + 9 of a shift
Thus the translation rule is
(x, y ) → (x - 10, y + 9 )
The answer to your question is the square root 2 over 2
First you have to order the set of values:
1, 1, 1, 2, 3, 3, 5, 7, 8, 8, 9
Now you just have to look for the middle value, which is 3.
Therefore your final answer is 3 :)
