Multiply the dimensions by 3 to convert to feet.
12 x 3 = 36 ft. 
15 x 3 = 45 ft. 
the dimensions are 36 ft. x 45 ft.

Answer with explanation:</h2>
The confidence interval for population mean is given by :-
 (1)
                   (1)
, where  = sample mean
 = sample mean 
z* = critical value.
SE = standard error
and  ,
 ,  = population standard deviation.
 = population standard deviation.
n= sample size.
As per given , we have


n= 15
It is known that ring diameter is normally distributed.
 
 
By z-table ,
The critical value for 95% confidence  = z*= 1.96
A 99% two-sided confidence interval on the true mean piston diameter :
 (using (1))
     (using (1))

 [Rounded to three decimal places]
  [Rounded to three decimal places]
∴  A 99% two-sided confidence interval on the true mean piston diameter  = (74.020, 74.022)
By z-table ,
The critical value for 95% confidence  = z*= 1.96
A 95% lower confidence bound on the true mean piston diameter:
  (using (1))
    (using (1))
 [Rounded to three decimal places]
 [Rounded to three decimal places]
∴  A 95% lower confidence bound on the true mean piston diameter= 74.020
 
        
        
        
Answer:
21=3(4)+9
Step-by-step explanation:
Assuming that the equation that you are trying the get is y=mx+b, plug in m, x, and b to get:
y=3(4)+9
y=12+9
y=21
