Step-by-step explanation:
 number x = 9.688888 is a rational number. This is because when you take x = 9.6888 and multiply 10 from x 10x = 96.888. So on and so forth.

Answer:
See explanations below
Step-by-step explanation:
Mean is the average of the data
Mean = sum of data/sample size
Sum of data = 89+99+80+5+90+0+100+95
Sum of data = 558
Sample size = 8
Mean = 558/8
Mean = 69.75
Median is the data value in the middle after rearrangement
Rearrange
0 , 5, 80) 89, 90, (95, 99 100
Median = 89+90/2
Median = 89.5
The parameter that gives a better picture of the scores is the Mean since all the given datas are taken into consideration
 
        
                    
             
        
        
        
The formula for simple interest is Interest= Principle·Rate·Time
If one of these is missing, just plug in what you know. For example, if time if the principle is missing just plug in the rest. Say the interest is $264, the rate is 6% and the time is 2 years. When its plugged it, it looks like this: 264= P ·0.06·2 Now you can work it out 0.06·2 is 0.12 so 264=P 0.12. Just divide by 0.12 and your done! You can do this with any letter and just put in the info you know. I hope that this helps you! :)
