Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades. 
explanation
 The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
 with very low p values are at the ends of the normal distribution. 
 
 
        
             
        
        
        
Answer:
3865.74 J/s
Step-by-step explanation:
mass of ice, m = 1 ton = 1000 kg 
time , t = 24 hours 
latent heat of fusion of ice, L  = 334000 J/kg 
Heat required to melt, H = m x L 
where, m is the mass of ice and L be the latent heat of fusion
So, H = 1000 x 334000 = 334 xx 10^6 J 
Rate of heat transfer = heat / time = 
Rate of heat transfer = 3865.74 J/s
thus, the rate of heat transfer is 3865.74 J/s.
 
        
             
        
        
        
He would earn $30 for 45 minutes. 
Example: 
60min=$40/hr
1min =$40/$60/hr
45min=$40/$60*45
$30 for 45min
