It's undefined, but I think you spelled it wrong.
Given:
The cost y (in dollars) of renting a segway for x hours is
![y=30x+25](https://tex.z-dn.net/?f=y%3D30x%2B25)
To find:
The initial fee and the cost per hour.
Solution:
We have,
...(i)
The slope intercept form of a linear equation is
...(ii)
where, m is slope is b is y-intercept or initial value.
From (i) and (ii), we get
![m=30,b=25](https://tex.z-dn.net/?f=m%3D30%2Cb%3D25)
The value of m is 30, so the slope is 30. It means cost per hour is $30.
The value of b is 25, so y-intercept is 25. It means the initial fee is $25.
XYA = (104 -52)/2
52 /2 = 26
the answer is 26 degrees
Answer:
![p(x\geq 520) = 0.0293](https://tex.z-dn.net/?f=p%28x%5Cgeq%20520%29%20%20%3D%200.0293)
Step-by-step explanation:
Given data:
random sample size n = 1000
Population size is N - 2,000,000
P = 0.49
We know
![\sigma_p = \sqrt{\frac{p*(1-p)}{n}}](https://tex.z-dn.net/?f=%5Csigma_p%20%3D%20%5Csqrt%7B%5Cfrac%7Bp%2A%281-p%29%7D%7Bn%7D%7D)
![\sigma_ p = \sqrt{\frac{0.49*(1-0.49)}{1000}} = 0.0158](https://tex.z-dn.net/?f=%5Csigma_%20p%20%3D%20%5Csqrt%7B%5Cfrac%7B0.49%2A%281-0.49%29%7D%7B1000%7D%7D%20%3D%200.0158)
Probability for having X =520
sample proportion ![\hat p = \frac{520}{1000} = 0.52](https://tex.z-dn.net/?f=%5Chat%20p%20%3D%20%5Cfrac%7B520%7D%7B1000%7D%20%3D%200.52)
![p(x\geq 520) = P(\hat p\geq)](https://tex.z-dn.net/?f=p%28x%5Cgeq%20520%29%20%20%3D%20P%28%5Chat%20p%5Cgeq%29%20)
![= P(Z\geq \frac{0.52 - 0.49}{0.0158})](https://tex.z-dn.net/?f=%3D%20P%28Z%5Cgeq%20%5Cfrac%7B0.52%20-%200.49%7D%7B0.0158%7D%29)
![= P(Z\geq 1.89) = 0.0293](https://tex.z-dn.net/?f=%3D%20P%28Z%5Cgeq%201.89%29%20%3D%200.0293)
![p(x\geq 520) = 0.0293](https://tex.z-dn.net/?f=p%28x%5Cgeq%20520%29%20%20%3D%200.0293)
1/3 because 2/6 divided 2/2 equals 1/3
