Answer:
Equation of line through () having undefined slope is given by
where α =90°
Now ,it is given that line passes through (97, 93)
So , equation of line is
→ = tan 90°
As, tan 90°=1/0
→ (x-97)×1= (y-73)×0
→ x-97 =0
→ x=97 , which is the required equation of line.
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.
