Answer: (1500.66,1599.34)
Step-by-step explanation:
Confidence interval for population mean:
,where 
= Sample mean , n= Sample size, z* = critical two tailed z-value , 
= population standard deviation.
As per given , we have
n= 16
square feet
square feet
Critical z-value = 
Confidence interval for population mean:
Required confidence interval: (1500.66,1599.34)

Hello.
(x + 2y) • (x - 13y)
Step by step solution :<span>Step 1 :</span><span>Equation at the end of step 1 :</span><span> ((x2) - 11xy) - (2•13y2)
</span><span>Step 2 :</span>Trying to factor a multi variable polynomial :
<span> 2.1 </span> Factoring <span> x2 - 11xy - 26y2</span>
Try to factor this multi-variable trinomial using trial and error<span>
</span>Found a factorization : (x + 2y)•(x - 13y)
Final result : (x + 2y) • (x - 13y)
