Observe the given data distribution table carefully.
The 5th class interval is given as,

The upper limit (UL) and lower limit (LL) of this interval are,

Thus, the upper-class limit of this 5th class is 17.4.
 
        
             
        
        
        
Answer:
2.6
Step-by-step explanation:
3/5 ---> ?/100
100/5 ---> 20
3       20         60
--  x           =   -------
5       20         100
60/100 = 6/10
6/10 as a decimal is 0.6
2 + 0.6
= 2.6

Answer:
C
Step-by-step explanation:
The general rule for the quadratic function is

Use the data from the table:

We get the system of three equations:

Subtract these equations:

From the first equation

Substitute it into the second equation:

So,

The quadratic function is 

 
        
             
        
        
        
Answer:
-19
Step-by-step explanation:
1) substitute a with 2 and b with 5 
(3 + 2)^2 * (4-5) + √36
2) solve the brackets and the square root 
(5^2) * (-1) + 6 
3) solve the power 
25 *(-1) + 6 
4) solve the multiplication 
-25 + 6 
5) solve the sum 
- 19
