What are the values of a and b?

English
1 answer:
topjm [15]3 years ago
6 0

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>

How is Scrooge developed in the Christmas Carol
ASHA 777 [7]
Ebenezer Scrooge is the ​protagonist​ (main character) of ‘A Christmas Carol’. He is a banker or ‘moneylender’ of sorts who owned his own ‘counting house’ alongside his late business partner Jacob Marley.

In the opening of the novella, Scrooge is presented as a miserly ​and ​misanthropic ​(someone who dislikes other people) businessman with a strong aversion to Christmas and the society around him in general. :)

I hope this helps
