Answer:
Table C is the correct option.
Step-by-step explanation:
We are given,
Number of students which knew French = 57
Number of students which knew both French and Spanish = 23
Number of students which knew Spanish but not French = 11
Number of students which knew neither French nor Spanish = 4
So, we get that,
Number of students not knowing French = 57 - 23 = 34
Hence, the table for the given situation is,
Knew Spanish Did not know Spanish Total
Knew French 23 34 57
Did not know French 11 4 15
Total 34 38 72
Thus, option C is correct.
57.7r + 23.23 =2.57
Subtract 23.23 from both sides:
57.7r = -20.66
Divide both sides by 57.7
r = -20.66 / 57.7
r = -0.358
round to nearest tenth = 0.4
