Final answer:
To determine the number of dots in the 75th figure, count the dots based on their corresponding positions relative to perpendicular hash marks.
Step-by-step explanation:
The 75th figure would have ___ dots. To determine the number of dots in the figure, we can observe that in the given information, each dot is described by its position relative to certain perpendicular hash marks. The third dot is one and two-thirds perpendicular hash marks to the right of the center top perpendicular hash mark, and the fourth dot is in the same position as the Car X figure (one perpendicular hash mark above the center right perpendicular hash mark). Using this information, we can count the number of dots in the 75th figure based on their corresponding positions.
