3/4 of the total students = 1230...
3/4x = 1230
x = 1230 * 4/3
x = 4920/3
x = 1640 <=== total students
        
             
        
        
        
Answer: 0.5

Square root both sides
L=√0.25
L=0.5
 
        
             
        
        
        
Answer:
The nth term of the sequence is
<h2>9n - 8</h2>
Step-by-step explanation:
The sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question 
a = 1
d = 10 - 1 = 9 or 19 - 10 = 9 or 28 - 19 = 9
So the nth term of the sequence is
A(n) = 1 + (n - 1)9
= 1 + 9n - 9
= 9n - 8
<h3>A(n) = 9n - 8</h3>
Hope this helps you
