Answer:
14 cm
Step-by-step explanation:
1. First, we need to find the total volume of Tank A. Tank A is a rectangular prism, and the volume of a rectangular prism is given by the formula length x width x height. In this case, it's...
50 cm x 70 cm x 70 cm = 245,000 cubic cm
2. Tank A was 2/7 full, so we need to find out how much water was in Tank A.
To find this, we multiply the total volume by the fraction that's full:
245,000 cm³ * 2/7 = 70,000 cm³.
3. This 70,000 cm³ of water was then poured into Tank B. We want to find out how high the water is in Tank B, so we need to divide the volume of the water by the base area of Tank B.
4. The base area of Tank B is given as 5000 cm². So, the height of the water in Tank B is 70,000 cm³ / 5000 cm² = 14 cm.
So, the height of the water in Tank B is 14 cm.
Hope this helps! :)

Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the residuals are all far from zero.
No, the equation is not a good fit because the sum of the residuals is a large number.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.
The equation that produced these predicted values is not a good fit given that the sum of the residuals is a large number.
The sum of the residuals in a regression is a value that is always supposed to be almost equal to zero in a regression analysis.
The residual tells us that the error term has been reduced to the minimum in the regression analysis.
