Answer: D. Is technology limiting our ability to have real communication with one another?
If a student decided to study the effects of technology on society, this question would be a good starting point. The fact that people are not communicating enough with one another could have enormous implications for society. For example, people might end up in more disagreements because of it. Different groups in society might never talk to each other, which means they might be fearful or suspicious of each other. Finally, cooperation and collaboration would be harder to achieve and maintain.
Answer:
a = –0.4 and b = 0.15
Explanation:
<em>Shanti wrote the predicted values for a data set using the line of best fit y = 2.55x – 3.15. She computed two of the residual values. What are the values of a and b?</em>
<em />
Residual values are the difference between Given and predicted value. That is:
Residual Value = Given - Predicted
Taking the values of the table:
a = 4.1 - 4.5 = -0.4
a = -0.4
And b is:
b = 7.2 - 7.05 = 0.15
b = 0.15
That means right answer is:
<h3>a = –0.4 and b = 0.15</h3>
