2x + y = x - y - 3 = 6
Add 3 to everything
2x + y + 3 = x - y - 3 + 3 = 6 + 3
2x + y + 3 = x - y = 9
2x + y + 3 = 9
2x + y = 6 = x - y
Add y to everything
2x + 2y = 6 + y = x
Since x = 6 + y substitute every x with 6 + y
2(6 + y) + 2y = x
12 + 4y = x
This is as simplified as I can get and then just place 12 + 4y into every x in the original problem then solve

Answer:
n^6 is the answer

![\frac{1}{\sqrt[4]{n} } * n^{\frac{25}{4} } = \frac{n^{\frac{25}{4} } }{n^{\frac{1}{4} } } = n^{\frac{25}{4} } - n^{\frac{1}{4} } = n^{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B%5Csqrt%5B4%5D%7Bn%7D%20%7D%20%2A%20n%5E%7B%5Cfrac%7B25%7D%7B4%7D%20%7D%20%3D%20%5Cfrac%7Bn%5E%7B%5Cfrac%7B25%7D%7B4%7D%20%7D%20%7D%7Bn%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%20%7D%20%20%3D%20n%5E%7B%5Cfrac%7B25%7D%7B4%7D%20%7D%20-%20n%5E%7B%5Cfrac%7B1%7D%7B4%7D%20%7D%20%3D%20n%5E%7B6%7D)
Step-by-step explanation:
Answer:
95% Confidence interval: (39.43, 61.58)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= $50.50
Sample size, n = 15
Alpha, α = 0.05
Sample standard deviation = 20
95% Confidence interval:
Putting the values, we get,
95% Confidence interval: (39.43, 61.58)
