Answer:
The margin of error is given below:
![E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }](https://tex.z-dn.net/?f=E%3Dz%20%5Ctimes%20%5Csqrt%7B%5Cfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%7D%7Bn%7D%20%7D)
Where:
![\hat{p}=\frac{26}{80}=0.325](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cfrac%7B26%7D%7B80%7D%3D0.325)
![\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }](https://tex.z-dn.net/?f=%5Ctherefore%20E%20%3D%20z%20%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.325%281-0.325%7D%7B80%7D%20%7D)
![=z \times 0.0523659](https://tex.z-dn.net/?f=%3Dz%20%5Ctimes%200.0523659)
Therefore, the option E = z*6% is correct as it closest to the given answer
I think the answer is the Last one
Answer:
Third Option:
or ![x=-3](https://tex.z-dn.net/?f=x%3D-3)
Step-by-step explanation:
![x^2+9x+18=0](https://tex.z-dn.net/?f=x%5E2%2B9x%2B18%3D0)
![(x+6)(x+3)=0](https://tex.z-dn.net/?f=%28x%2B6%29%28x%2B3%29%3D0)
or ![x=-3](https://tex.z-dn.net/?f=x%3D-3)
Answer:
The variable X represents:
X = the number of books
The real world situation can be:
1.) Jennie reads books. She reads each books for
2.) Jennie wants to read book at least 5 books today.
Write an inequality that models the minimum number of books that Jennie needs to read.
The inequality for this situation is:
![2x \: \geqslant \: 5](https://tex.z-dn.net/?f=2x%20%5C%3A%20%20%5Cgeqslant%20%20%5C%3A%205)
The expression 6x^2-1 cannot be factored or simplified any further.
