Below is the graph of the boa constrictor population you learned about in the video. The x-axis is t, the time in years, and the y-axis is p(t), the snake population for any given year. In this case, t = 0 indicates the year they started keeping track of the constrictor population. Scientists want to know how the population is changing every two years so they can make predictions about the future.

The graph is of a function in the form p(t) = a • bt. What is the function?

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?
