Question

the graph shows the annual heart attack rate per 10,000 men as a function of blood cholesterol level. use the graph to approximate the annual heart attack rate per 10,000 men for those whose blood cholesterol level is 175 mg/dl. the heart attack rate for a blood cholesterol level of 175 mg/dl is □ per 10,000 men. (type a whole number. round to the nearest 5 as needed)

Explanation:

Step1: Analyze the graph

The graph has the x - axis as blood cholesterol level (mg/dl) and the y - axis as heart attack rate per 10,000 men. We need to find the y - value when \(x = 175\) mg/dl.

Step2: Locate \(x = 175\) on the x - axis

Find the position of 175 on the x - axis (mg/dl scale). Then, move up (or down, depending on the graph's orientation) to the curve representing the heart attack rate. Then, move horizontally to the y - axis to find the corresponding heart attack rate. From the graph (assuming a typical relationship where as cholesterol increases, heart attack rate may change in a certain way, and by visually inspecting the grid), when \(x=175\) mg/dl, the y - value (heart attack rate per 10,000 men) is approximately 100 (after rounding to the nearest 5, if needed. Since 100 is already a multiple of 5, we can take it as is).

Answer:

100
