Graph y>5x+2 on the vertical line which is the wireline the one that goes up-and-down you put a point on to go up to then you do the slope go up five and one to the right you make a broken line on the second graph Y <_ -X+1
On the vertical line which is the Y start on one put it up there then go down one and one to the right down one went to the right this is a solid line and color everything underneath it says it's less than
Answer:
The average life of the mice that are placed on this diet is less than 40 months.
Step-by-step explanation:
Consider the provided information.
When 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that μ < 40.
The null and alternative hypothesis are:
![H_0:\mu=40\\H_a:\mu](https://tex.z-dn.net/?f=H_0%3A%5Cmu%3D40%5C%5CH_a%3A%5Cmu%3C40)
64 mice that are placed on this diet have an average life is 38 months with a standard deviation of 5.8 months.
Therefore, ![n = 64, \bar x=38\ and\ \sigma=5.8](https://tex.z-dn.net/?f=n%20%3D%2064%2C%20%5Cbar%20x%3D38%5C%20and%5C%20%5Csigma%3D5.8)
Use the formula: ![z=\dfrac{\bar x-\mu}{\frac{\sigma}{\sqrt{n} }}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B%5Cbar%20x-%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%20%7D%7D)
Substitute the respective values in the above formula.
![z=\dfrac{38-40}{\frac{5.8}{\sqrt{64} }}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B38-40%7D%7B%5Cfrac%7B5.8%7D%7B%5Csqrt%7B64%7D%20%7D%7D)
![z=-\dfrac{2}{\frac{5.8}{8}}\approx-2.76](https://tex.z-dn.net/?f=z%3D-%5Cdfrac%7B2%7D%7B%5Cfrac%7B5.8%7D%7B8%7D%7D%5Capprox-2.76)
Now using the table ![P(Z](https://tex.z-dn.net/?f=P%28Z%3Cz%29%3D0.029)
The p value is smaller than 0.05 so reject the null hypothesis.
Therefore, the average life of the mice that are placed on this diet is less than 40 months.
The equation for a line with slope m through point (h, k) can be written in "point-slope" form as
.. y -k = m(x -h)
You have m = -4, (h, k) = (-2, -6), so the equation of your line is
.. y +6 = -4(x +2)
