Answer:
9 students in each row
Step-by-step explanation:
Given : 54 students, arranged in 6 rows (with equal students), singing 7 songs.
No of students in one row x No of rows = Total students
So, No of students in one row = Total students / No of rows
No of students in each row = 54 / 6 = 9
y is equal to 7
the ratios on each side are 2 to 14, 9 to 63, and if you divide 14 by 2 you get 7. and if you divide 63 by 9 you get 7
(X-3)(x-3) is the answer
.758 or 163/215
Conditional probablity formula:
(A|B)= (A∩B)/B
we have
.652/.86
this equals .758 or 163/215
