Answer:
5 groups of 5
Step-by-step explanation:
No. of students = 32No. of students in each group = 5No. of students in ONE group = 7No. of groups of 5 = 32 - 7 = 25 = 25/5 = 5
f(x) = a - x
y = a - x
y + x = a - x + x
y + x = a
y + x - y = a - y
x = a - y
f-¹(x) = a - x
The answer to your question is: x = 4.44
Data
ln(x + 1) − ln(2) = 1
In (x + 1)/2 = 1
(x + 1) / 2 = e¹
x + 1 = 2 (2.7183)
x = 5.44 - 1
x = 4.44
