Answer:
1329.85≤μ≤1330.14
Step-by-step explanation:
z score for 99% confidence interval
from the z table we can find that the score for 99% confidence is 2.58
formula
z=}[/tex]}[/tex]
where
x-sample mean
μ-population mean
σ-population standard deviation
n-sample size
2.58=}[/tex]}[/tex]
1330-2.58×24÷442≤μ≤1330+2.58×24÷442
1329.85≤μ≤1330.14
The expression for the area of the shaded region is s^2 - pir^2
<h3>Area of composite figure</h3>The formula for calculating the area of the shaded part in the given equation is expressed as:
Area area of square. - area of circle
Since
Area of square = s^2
Area of circle = pir^2
substitute
Area of shaded part = s^2 - pir^2
Hence the expression for the area of the shaded region is s^2 - pir^2
