Answer:
Radius of large cylinder ![= 10.39 feet\\](https://tex.z-dn.net/?f=%3D%2010.39%20feet%5C%5C)
Step-by-step explanation:
Volume of the larger tank is three times the volume of smaller tank
Volume of smaller tank
![= \pi r^{2} h\\= (3.14) * 6^{2} * 20\\= 2260.8 ft^{3} \\](https://tex.z-dn.net/?f=%3D%20%5Cpi%20r%5E%7B2%7D%20h%5C%5C%3D%20%283.14%29%20%2A%206%5E%7B2%7D%20%2A%2020%5C%5C%3D%202260.8%20ft%5E%7B3%7D%20%5C%5C)
Volume of larger tank
![= 3 * 2260.8 ft^3\\= 6782.4 ft^3\\](https://tex.z-dn.net/?f=%3D%203%20%2A%202260.8%20ft%5E3%5C%5C%3D%206782.4%20ft%5E3%5C%5C)
Or it can also be written as
![\pi r^{2} h = 6782.4 ft^3\\(3.14) * ( r^2) 20 = 6782.4 ft^3\\r^2 = 108\\r = 10.39](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D%20h%20%3D%206782.4%20ft%5E3%5C%5C%283.14%29%20%2A%20%28%20r%5E2%29%2020%20%3D%206782.4%20ft%5E3%5C%5Cr%5E2%20%3D%20108%5C%5Cr%20%3D%2010.39)
Answer:
Residual = 11.462
Since the residual is positive, it means it is above the regression line.
Step-by-step explanation:
The residual is simply the difference between the observed y-value which is gotten from the scatter plot and the predicted y-value which is gotten from regression equation line.
The predicted y-value is given as 20.7°
The regression equation for temperature change is given as;
y^ = 9.1 + 0.6h
h is the observed amount of humidity and it's given to be 23 percent or 0.23.
Thus;
y^ = 9.1 + 0.6(0.23)
y^ = 9.238
Thus:
Residual = 20.7 - 9.238
Residual = 11.462
Since the residual is positive, it means it is above the regression line.
Answer:
Number 1 and Number 4
Step-by-step explanation:
By factoring, you can figure out the roots (x = -2 or x = 2)...
1. x^2 - 4 = 0
--> (x + 2)(x - 2) = 0
--> x = -2, x = 2
2. x^2 + 4 = 0
--> factors weirdly, so I won't write it. You'd have to use the quadratic formula.
3. 3x^2 + 12 = 0
--> 3 (x^2 + 4) = 0
--> factors weirdly (same as above)
4. 4x^2 - 16 = 0
--> 4 (x^2 - 4) = 0
--> 4 (x+2) (x-2) = 0
--> x = -2, x = 2
5. 2 (x-2) 2 = 0
--> x = 2
