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)
Answer:
Domain: All Real Numbers or (-∞, ∞)
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that any value of <em>x</em> can be plugged into the function.
∴ Our answer is all real numbers
Answer:The answer is A - symmetry.
None of the other options really have bearing in relation to the question.
Step-by-step explanation:
To solve, I would write an equation like this: 0.3=x/70 , where x is the number of aces divided by 70 games and 0.3 is his ace average.
0.3=x/70
x=70x0.3
=21
The player has served 21 aces.
Check:
21/70
=0.3
