Answer:
E
Step-by-step explanation:
Irrational means cannot be put into a fraction. Or random repeating decimals is how I remember it.
√48 can be simplified to equal 4√3. √3 cannot be put into fraction form.
 
        
             
        
        
        
Answer:
Probability of sum of pips on two faces is at least 9 = 
Step-by-step explanation:
Experiment:  Throwing two fair dice.
Total no of Outcome =  = 36
 = 36
Sample space (list of outcome) is attached.
Let E be the event that sum of pips on two faces is at least 9.

Favorable outcome are where sum is 9 , 10 , 11 and 12.
From Sample space, No. of Favorable outcome = 10
∴

Answer:
D,E are not functions
Step-by-step explanation:
A function is a relation in which every  input has not more than one output.But the output of the inputs may be same.Here in D the input 1 has 4 different outputs as 1,2,3,4.So its not a function.Similarly in E 6 has 2 outputs as 2 and -1.For remaining sets the inputs has only one output.so they are functions.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Assuming we want to find the equation (74,2)  and (4,9)
This is an equation of a straight.
Let this equation be y=mx+b.

We substitute the slope  and (4,9) to get:

We  rewrite in standard form to get:
