Answer: 
Step-by-step explanation:
We have the equation 
where P represents the payment and w represents the amount of water used.
To calculate the monthly payment that corresponds to 12 units of water you must do 
in the main equation and solve for the variable P.
To solve for the confidence interval for the true average
percentage elongation, we use the z statistic. The formula for confidence
interval is given as:
Confidence interval = x ± z σ / sqrt (n)
where,
x = the sample mean = 8.63
σ = sample standard deviation = 0.79
n = number of samples = 56
From the standard distribution tables, the value of z at
95% confidence interval is:
z = 1.96
Therefore substituting the known values into the
equation:
Confidence interval = 8.63 ± (1.96) (0.79) / sqrt (56)
Confidence interval = 8.63 ± 0.207
Confidence interval = 8.42, 8.84

Answer:
Since we have given that
Surface area of sphere = 576 pi cm. sq.
As we know the formula,
Surface area of sphere is given by
So, the volume of a sphere would be
Hence, the required volume is 7241.14 cm³.
Step-by-step explanation:
The value should be -49. Hope this helps.
Answer:
143
Step-by-step explanation:
41 + 102 = 143
180- 143= 37
180 - 37 = 143
