This graph shows the rate of a scuba diver’s ascent to the surface. What does the y-intercept of the graph represent? A. The scuba diver ascended at a rate of 10 meters per minute.

B. The scuba diver started her ascent at the surface of the water.

C. The scuba diver ended her ascent 35 meters below the surface of the water.

D. The scuba diver was 35 meters below the surface of the water at the start of the ascent.

What are the relative frequencies to the nearest hundredth of the columns of the two-way table? a b group 1 102 34 group 2 18 14

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
