Answer:
y+x is greater than or equal to -1
Step-by-step explanation:
 
        
                    
             
        
        
        
A total of 440 students took part in the survey. Each student makes up 0.8181818182% of the central angle of the circle graph. You get to this number by dividing 360 degrees by 440 students. Then you simply multiply this number by 110 students (who liked the program).
0.8181818182%*110=90 degrees
        
             
        
        
        
An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. <u>Instead, the numbers in the decimal would go on forever, without repeating.  Ex) .7583947262.........    It doesn't repeat and goes on forever</u>
 
        
             
        
        
        
A mean is the total of all numbers/ how many numbers there are.
A median is a middle number. An equation you can use is (x+1/2). x is how many numbers there are
