Answer:
25.9666 m
Step-by-step explanation:
The 4 arches combine to for a circle, so then you can find the area of the shaded region by subtracting the area of the square from the area of the circle.
The formula for area of a circle is A=r^2
Since the radius of the circle would be 11/2 or 5.5, the area if the circle would be x 5.5^2. This equals 95.0334.
The area of the square would be 11 x 11 = 121.
The 121-95.0334= 25.9666 m
Answer:
D. x=10, y=12
Step-by-step explanation:
Answer:
k = 13
Step-by-step explanation:
Given
= 4
Multiply both sides by 3.25 to clear the fraction
k = 4 × 3.25 = 13
The standard error of the mean is 12.
The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.
The standard error S.E of the mean can be calculated by using the formula:
where;
- standard deviation = 24
- sample size n = 4
S.E = 12
