Easily we can use formula y=(x-h)^2 +k
as equation of a parabola if vertex was (h,k):
Y=(x-1)^2 + 3
and maybe node (2,6) is incorrect for this vertex of a parabola!!!
Answer:
7.719km
Step-by-step explanation:
10 - 2.281 is 7.719
Answer: 5
Step-by-step explanation:
Let A denotes the number of major defects and B denotes the number of design defect.
By considering the given information, we have
![U=28\ ;\ n(A)=14\ ;\ n(B)=8\ \ ;\ n(A^c\cap B^c)=1](https://tex.z-dn.net/?f=U%3D28%5C%20%3B%5C%20n%28A%29%3D14%5C%20%3B%5C%20n%28B%29%3D8%5C%20%5C%20%3B%5C%20n%28A%5Ec%5Ccap%20B%5Ec%29%3D1)
Now, the number of major defects or design defects:
![n(A\cup B)=U-n(A^c\cap B^c)=28-11=17](https://tex.z-dn.net/?f=n%28A%5Ccup%20B%29%3DU-n%28A%5Ec%5Ccap%20B%5Ec%29%3D28-11%3D17)
Also,
![n(A\cap B)=n(A)+n(B)-n(A\cup B)\\\\\Rightarrow\ n(A\cap B)=14+8-17=5](https://tex.z-dn.net/?f=n%28A%5Ccap%20B%29%3Dn%28A%29%2Bn%28B%29-n%28A%5Ccup%20B%29%5C%5C%5C%5C%5CRightarrow%5C%20n%28A%5Ccap%20B%29%3D14%2B8-17%3D5)
Hence, the number of design defects were major=5
