Answer:
x= ± sqrt [ y/a]
Step-by-step explanation:
y = ax^2
y/a = x^2
x^2 = y/a
x= ± sqrt [ y/a]

12% error. To find out subtract the difference between the estimate and the actual amount sold and divide the difference by the estamite.
Answer:
Step-by-step explanation:
Given that X, the number of square feet per house is N(mean, 137)
Sample size = 19
Sample mean x bar =1350 sq ft
Since population std dev is given,
std error of sample = 
Since sample size is small, t critical value can be used
df = 18
t value for 80% two tailed = 1.333
Margin of error = ±1.333(std error) = ±
Confidence interval = sample mean ±margin of error
=
