Answer:
1/4+m=2/3
Step-by-step explanation:
The total rectangle is equal to 2/3 as shown on the bottom rectangle.
1/4 and m fit into that same rectangle meaning that 1/4+m=2/3

Answer:
D
Step-by-step explanation:
The factored from of a polynomial can be found from the zeros or x-intercepts of the graph.
The x-intercepts here are x= -3 and x= 3.
Then the factors are x+3 and x-3.
So the factored form is (x+3)(x-3).
Answer: The confidence interval would be (0.2928,0.3672).
Step-by-step explanation:
Since we have given that
Total number of vehicles = 432
Number of SUVs sold = 142
So, it becomes,
![\hat{p}=\dfrac{x}{n}=\dfrac{142}{432}=0.33](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cdfrac%7Bx%7D%7Bn%7D%3D%5Cdfrac%7B142%7D%7B432%7D%3D0.33)
At 90% confidence interval,
z = 1.645
So, the confidence interval would be
![\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\=0.33\pm 1.645\sqrt{\dfrac{0.33\times 0.67}{432}}\\\\=0.33\pm 0.0372\\\\=(0.33-0.0372,0.33+0.0372)\\\\=(0.2928,0.3672)](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%5Cpm%20z%5Csqrt%7B%5Cdfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%29%7D%7Bn%7D%7D%5C%5C%5C%5C%3D0.33%5Cpm%201.645%5Csqrt%7B%5Cdfrac%7B0.33%5Ctimes%200.67%7D%7B432%7D%7D%5C%5C%5C%5C%3D0.33%5Cpm%200.0372%5C%5C%5C%5C%3D%280.33-0.0372%2C0.33%2B0.0372%29%5C%5C%5C%5C%3D%280.2928%2C0.3672%29)
Hence, the confidence interval would be (0.2928,0.3672).
