Answer:
B) 15.85%
Step-by-step explanation:
normalcdf(minimum,maximum,μ,σ)
normalcdf(39,189,264,75)
≈0.1573
≈15.73%
Therefore, the closest answer is B
Answer:
100.26
Step-by-step explanation:
You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.
This is what that would look like:
1. Divide 6 (the diameter) by 2 because ![r=\frac{1}{2} d](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B1%7D%7B2%7D%20d)
![r=\frac{1}{2} 6](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B1%7D%7B2%7D%206)
![r=3](https://tex.z-dn.net/?f=r%3D3)
2. plug into the formula ![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
![A=\pi 3^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%203%5E%7B2%7D)
3. square the 3
![A=\pi 9](https://tex.z-dn.net/?f=A%3D%5Cpi%209)
4. multiply 9 by 3.14 (pi)
![A=28.26](https://tex.z-dn.net/?f=A%3D28.26)
This means the area of both the semi circles added together would equal 28.26
Then you would use the formula
to find the area of the rectangle
1. plug in the numbers given
· ![6](https://tex.z-dn.net/?f=6)
2. solve
![A=72](https://tex.z-dn.net/?f=A%3D72)
Then add the area of the semicircles to the area of the rectangle
![A=28.26+72](https://tex.z-dn.net/?f=A%3D28.26%2B72)
to get the area of the entire figure:
![A=100.26](https://tex.z-dn.net/?f=A%3D100.26)
Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
Let x be that number:
x +10 -2 +4 + 3 - 1 - 7 +1 = 0
x +8 = 0
and x = - 8
