okay 1 student = 1/20 chance of picking yellow
1/20 (30/30) = 30/600 chance of picking yellow out of 30 studnets
30/600 = 0.05 = 5% chance of choosing yellow.
I each studnet picks 1 yellow marker. Is that all the options?
 
        
                    
             
        
        
        
Answer:
4 ft downwards
Step-by-step explanation:
old height off the ground :
7^2+b^2=25^2
49+b^2=625
b^2=576
b=24
new height off the ground : 
7+8=15
15^2+ b^2 =25^2
225+b^2 = 625
b^2 = 400
b=20
difference between heights : 
24 - 20 =  4
 
        
             
        
        
        
Well you divide $42.25 by 6.5 and you’ll get your hourly pay which is $6.25
