A psychologist collects data on the time, w, in minutes, people walk each day and their scores, t ,on a stress test. The scores

are from 0 to 100, with higher scores meaning more stress. She finds that there is a negative linear association between w and t that is best modeled by the equation t=−2.5w+48.1 .
What is the meaning of 48.1 in this equation?

For each additional minute spent walking, the model predicts that a person's score on the stress test will go down by about 48.1 points.

The people in the study walked an average of 48.1 minutes each day.

The model predicts that a person who does not walk each day will score about 48.1 on the test.

The people who walked each day had an average score of 48.1 on the stress test.

fredd [130]

Answer:

Since we do not know the balance we should start with, a general answer:

b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Step-by-step explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals
