Is that all? My Algebra is freackin hard compared to this. Anyways, The way I understand this, is that we will have 3 (liters of water) +0.5 (half a liter of lemonade) =3.5 liters of liquid
so the question would be: how many times does fit into 3.5?
if you want to divide by a fraction, you need to multiply by the reverse of it.
so the answer is: 10 servings of lemonade ( and a little bit will be left over for half a serving).
Hope this helps!
The table is missing in the question. The table is attached below.
Solution :
Let X = appraised value
Y = area (square feet)
The regression line is given by :
![$\hat y = b_0+b_1X$](https://tex.z-dn.net/?f=%24%5Chat%20y%20%3D%20b_0%2Bb_1X%24)
![$b_1=\frac{n\sum XY-\sum X \sum Y}{n \sum X^2-(\sum X)^2}$](https://tex.z-dn.net/?f=%24b_1%3D%5Cfrac%7Bn%5Csum%20XY-%5Csum%20X%20%5Csum%20Y%7D%7Bn%20%5Csum%20X%5E2-%28%5Csum%20X%29%5E2%7D%24)
![$=\frac{15(5964990)-(2157)(33370)}{15(404799)-(2157)^2}$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B15%285964990%29-%282157%29%2833370%29%7D%7B15%28404799%29-%282157%29%5E2%7D%24)

![$=\frac{33370}{15}-\left(12.3267 \times \frac{2157}{15}\right)$](https://tex.z-dn.net/?f=%24%3D%5Cfrac%7B33370%7D%7B15%7D-%5Cleft%2812.3267%20%5Ctimes%20%5Cfrac%7B2157%7D%7B15%7D%5Cright%29%24)
![$b_0=452.0841$](https://tex.z-dn.net/?f=%24b_0%3D452.0841%24)
The regression line is :
![$\hat Y = 452.0841+12.3267 X$](https://tex.z-dn.net/?f=%24%5Chat%20Y%20%3D%20452.0841%2B12.3267%20X%24)
To estimate the error variance, we have:
Error variance, ![$\sigma =\sqrt{\frac{\sum (Y-\hat Y)^2}n-2{}}$](https://tex.z-dn.net/?f=%24%5Csigma%20%3D%5Csqrt%7B%5Cfrac%7B%5Csum%20%28Y-%5Chat%20Y%29%5E2%7Dn-2%7B%7D%7D%24)
![$=\sqrt{\frac{587682.3}{15-2}}$](https://tex.z-dn.net/?f=%24%3D%5Csqrt%7B%5Cfrac%7B587682.3%7D%7B15-2%7D%7D%24)

Answer:
10 hours
Step-by-step explanation:
320 = 30x + 20
300 = 30x
x = 10
A coefficient is a number that is attached to a term.
For example:
3x² - 5x + 6 = 0
The coefficient of x² is 3.
The coefficient of x = -5.
Hope this explains it.
