at -12 feet elevation (12 feet below ground level), the basement starts
62 feet from that level is the roof
so count 62 units up from -12 and get 50 feet above ground level (60-12=50)


answer is 50 feet above ground level

Help me Describe the location of the solid figure relative to the dashed figure.

Answers

The location of the solid figure relative to the dashed figure can be described in terms of precision and accuracy. In some figures, the dots are concentrated close to one another, indicating high precision, but they are rather far away from the actual location, indicating low accuracy. The plot lines on the left and right represent different starting points, indicating their relative positions.

The location of the solid figure relative to the dashed figure can be described in terms of precision and accuracy. Precision refers to how closely the data points are concentrated to one another, while accuracy refers to how close the data points are to the actual location.

In Figure 1.22, Figure 1.25, and Figure 1.23, the dots are concentrated close to one another, indicating high precision. However, they are rather far away from the actual location of the restaurant, indicating low accuracy.

In the plot on the left and right, the lines represent the movement from one point to another. The plot on the right shows a line from (0,2) to (3,2), while the plot on the left shows a line from (0,8) to (3,2). The difference in the starting points of the lines indicates their relative positions.
