The answer would be; 45x - 265 < 400
because you need to now how much sodas can she still drink by subtracting the milligrams that she already had. (-265)
<em>The word usage in last sentence of the question is not well presented. However, I can understand that you intend to solve for the width of the park</em>
Answer:
![Width = 2\ km](https://tex.z-dn.net/?f=Width%20%3D%202%5C%20km)
Step-by-step explanation:
Given
![Length = \frac{3}{8}km](https://tex.z-dn.net/?f=Length%20%3D%20%5Cfrac%7B3%7D%7B8%7Dkm)
![Area = \frac{3}{4}km^2](https://tex.z-dn.net/?f=Area%20%3D%20%5Cfrac%7B3%7D%7B4%7Dkm%5E2)
Required
Determine the Width
For a rectangle:
![Area = Length * Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width)
Substitute for Area and Length
![\frac{3}{4} = \frac{3}{8} * Width](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B3%7D%7B8%7D%20%2A%20Width)
Multiply both sides by ![\frac{8}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D)
![\frac{8}{3} * \frac{3}{4} = \frac{3}{8} * \frac{8}{3}* Width](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D%20%2A%20%5Cfrac%7B3%7D%7B4%7D%20%3D%20%5Cfrac%7B3%7D%7B8%7D%20%2A%20%5Cfrac%7B8%7D%7B3%7D%2A%20Width)
![\frac{8}{3} * \frac{3}{4} = Width](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B3%7D%20%2A%20%5Cfrac%7B3%7D%7B4%7D%20%3D%20%20Width)
![\frac{24}{12} = Width](https://tex.z-dn.net/?f=%5Cfrac%7B24%7D%7B12%7D%20%3D%20Width)
![2 = Width](https://tex.z-dn.net/?f=2%20%3D%20Width)
![Width = 2\ km](https://tex.z-dn.net/?f=Width%20%3D%202%5C%20km)
Answer:
Following are the response to the given question:
Step-by-step explanation:
Testing hypothesis:
![H_0: p \geq 0.2 \\\\H_a: p < 0.2](https://tex.z-dn.net/?f=H_0%3A%20p%20%5Cgeq%200.2%20%20%20%5C%5C%5C%5CH_a%3A%20p%20%3C%200.2)
When it's a lower tailed test:
claimed proportion,
Significance level,
calculating statistics
:
![\hat{p}, \sigma_{\hat{p}}=\sqrt{\frac{P \times (1-p)}{n}}\\\\](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%2C%20%5Csigma_%7B%5Chat%7Bp%7D%7D%3D%5Csqrt%7B%5Cfrac%7BP%20%5Ctimes%20%281-p%29%7D%7Bn%7D%7D%5C%5C%5C%5C)
