Answer:
And the real value for this case is y=14. The residual is defined as:
Replacing we got:
And the best answer would be:
-2
Step-by-step explanation:
For this case we know that the best fit line for the relationship between x and y is given by:
And we know that an individual in the dataset has a score of 10 on the x-variable and a score of 14 on the y-variable. So then we can find the estimated value like this:
And the real value for this case is y=14. The residual is defined as:
Replacing we got:
And the best answer would be:
-2
Answer:
100 texts
Step-by-step explanation:
Let the amount of text messages be x. Since we are looking at making both plans equal, we add the fixed monthly charges to the number of messages multiplied by the cost.
The total amount charged by Totally will be 30 + 0.2x
The total amount charged by Gnarly will be
40 + 0.1x
Now since we are trying to get the number of text messages that make both charges equal, we equate the two charges and that is:
30 + 0.2x = 40 + 0.1x
40 - 30 = 0.2x - 0.1x
0.1x = 10
x = 10/0.1 = 100 texts
