7x7x7x7x7=?
Think about...
You are multiplying 7 five times. When use use an exponent your are simply showing the amount of time 7 (or whatever your number is) has been multiplied by itself in a more compact form.
For example:
5^8=5x5x5x5x5x5x5x5
Or
4x4x4=4^3
So,
5y*3 is the open phrase the student uses to model "the sum of 5y and 3".
"The sum of" means addition. The student put 5y*3, while the sum of 5y and 3 is actually 5y + 3.

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)
