Answer:
Step-by-step explanation:
From the information given:
For Adult Men
Mean
= 69.5
Standard deviation
= 2.4
observed value X = 74
For Adult Women
Mean
= 63.8
Standard deviation
= 2.6
observed value X = 70
Therefore ; the values for their z scores can be obtained in order to determine who is more unusually tall within his or her respective sex
For Adult Men :
![z = \dfrac{X- \mu}{\sigma}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7BX-%20%5Cmu%7D%7B%5Csigma%7D)
![z = \dfrac{74- 69.5}{2.4}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B74-%2069.5%7D%7B2.4%7D)
![z = \dfrac{4.5}{2.4}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B4.5%7D%7B2.4%7D)
z = 1.875
For Adult Women :
![z = \dfrac{X- \mu}{\sigma}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7BX-%20%5Cmu%7D%7B%5Csigma%7D)
![z = \dfrac{70- 63.8}{2.6}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B70-%2063.8%7D%7B2.6%7D)
![z = \dfrac{6.2}{2.6}](https://tex.z-dn.net/?f=z%20%3D%20%5Cdfrac%7B6.2%7D%7B2.6%7D)
z = 2.3846
Thus; we can conclude that , the women is more unusually tall within his or her respective sex
They have the same slope, but g(x) intercepts the y axis higher.
Answer:
![x1 = 2 \\ x2 = - \frac{3}{2}](https://tex.z-dn.net/?f=x1%20%3D%202%20%5C%5C%20x2%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20)
Step-by-step explanation:
![x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{1 + - \sqrt{ {( - 1)}^{2} - 4(2)( - 6) } }{2(2)} \\ x = \frac{1 + - \sqrt{1 + 48} }{4} \\ x = \frac{1 + - \sqrt{49} }{4} \\ x = \frac{1 + - 7}{4} \\ \\ x1 = \frac{1 + 7}{4} = \frac{8}{4} = 2 \\ x2 = \frac{1 - 7}{4} = - \frac{6 }{4} = - \frac{3}{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%20b%20%2B%20%20-%20%20%5Csqrt%7B%20%7Bb%7D%5E%7B2%7D%20-%204ac%20%7D%20%7D%7B2a%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1%20%2B%20%20-%20%20%5Csqrt%7B%20%7B%28%20-%201%29%7D%5E%7B2%7D%20-%204%282%29%28%20-%206%29%20%7D%20%7D%7B2%282%29%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1%20%2B%20%20-%20%20%5Csqrt%7B1%20%20%2B%2048%7D%20%7D%7B4%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1%20%2B%20%20-%20%20%5Csqrt%7B49%7D%20%7D%7B4%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B1%20%2B%20%20-%207%7D%7B4%7D%20%20%5C%5C%20%20%5C%5C%20x1%20%3D%20%20%5Cfrac%7B1%20%20%2B%207%7D%7B4%7D%20%20%3D%20%20%5Cfrac%7B8%7D%7B4%7D%20%20%3D%202%20%5C%5C%20x2%20%3D%20%20%5Cfrac%7B1%20-%207%7D%7B4%7D%20%20%3D%20%20%20-%20%5Cfrac%7B6%20%7D%7B4%7D%20%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B2%7D%20)
If you mean by completely factored form of x^4y - 4x2y - 5y
Then the answer is y (x^2 - 5) (x^2 + 1)
