Answer:
The first box in the girl row is 18, the second one in the boy row is 8, and the bottom one is also 18.
Step-by-step explanation:
To get 81 to 9, you have to divide by 9, which means you have to do the same to 72. You get the ration 9 to 8, 9 being girls and 8 being guys. Then to get from 8 guys to 16, you have to multiply by 2, which means you do the same to 9 and get the answer of 18 girls. Hope this helps :)
 
        
             
        
        
        
Answer:
y = 5x + 8
Explanation:
The slope is 5, and the y intercept is 8 so following the format of the equation, the equation for this line is:
y = 5x + 8
 
        
                    
             
        
        
        
change,c = 20 - p
so in Excel for example
put 20 in column a
put 11.59, 17.50 etc in column b
in column c put the equation '=20 - b1'
 
        
                    
             
        
        
        
The mean is 35/5=7
The variance is the average of the sum of squared differences of each element from the mean:
v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5
v=(0+4+16+36+16)/5
v=14.4
