That is 62x9 which is 9x2=18 and 9x60=540 so you then add 540+18=558 chairs
3n-5=-48-40n
Move -40n to the other side. Sign changes from -40n to +40n.
3n+40n-5=-48= -48-40n+40n
3n+40n-5=-48
Move -5 to the other side.
3n+40n-5+5=-48+5
3n+40n=-43
43n=-43
Divide by 43 for both sides
43n/43=-43/43
n=-1

Step-by-step explanation:
From the question we are told that
The population mean is 
The standard deviation is 
The sample size is n = 25
Generally the probability that a boy born full term in the US weighs less than 7 lbs is mathematically represented as


=> 
From the z table the area under the normal curve to the left corresponding to -0.6364 is

=> 
Generally the standard error of mean is mathematically represented as

=> 
=> 
Generally the probability that the average weight of 25 baby boys born in a particular hospital have an average weight less than 7 lbs is mathematically represented as

=> 
From the z table the area under the normal curve to the left corresponding to -3.1818 is
=> 
=>
