Question
A psychologist conducting a memory experiment provided participants with a list of three-letter sequences. Immediately after the experiment, the participants remembered 100% of the sequences. The psychologist found that the percentage of sequences the participants remembered decreased by 30% for every 3-second interval that passed. Which function best models this situation, where P is the percentage of sequences the participants remembered, and t is the time, in seconds, that passed?
- P(t)= 100(0.30)3t
- P(t)= 100(0.30)t
- P(t)=100(0.70)t
The correct answer is:
The 100% of the sequence.
The amount of sequence of rememberence decreased is 30%
The amount of sequence rememberence remains is 70%
The time is 3 seconds
The percentage of sequence remembered = 100(70%) t/3
P(t) = 100 (0.70) t/3

For a sample of 13 red alder trees, an arborist measured each tree’s diameter, in centimeters (cm), at a height of 1.4 meters. The arborist then counted the number of growth rings at this height. Each point in the scatterplot represents the diameter and number of rings for each tree. A line of best fit for these data is also shown.
For how many of the trees in the sample is the number of growth rings greater than the number predicted by the line of best fit?
