Answer:
After 8 months of internet use both the connection will cost the same.
Step-by-step explanation:
Fast Internet charges $40 for installation and $52.45 per month.
So, the total cost after using x months of the internet in Fast Internet will be
C = 40 + 52.45x
Quick Internet has free installation but charges $57.45 per month.
So, the total cost after using x months of the internet in Quick Internet will be
C = 57.45x
Now, if those two cost are same then
40 + 52.45x = 57.45x
⇒ 5x = 40
⇒ x = 8
Therefore, after 8 months of internet use both the connection will cost the same. (Answer)
Answer:
Hello your question has a disjointed equation attached to it and it is also incomplete attached below is the correct and complete question
A teacher believes that the third homework assignment is a key predictor in how well students will do on the midterm. Let x represent the third homework score and y the midterm exam score. A random sample of last terms students were selected and their grades are shown below
answer :
y-intercept = 25.9047
slope = 2.8420
Step-by-step explanation:
Determine the slope for the regression equation and y intercept
The regression equation ( gotten using excel ; attached below is the excel sample on how the equation was gotten )
y = 25.9047 + 2.8420x
from the equation gotten above
y-intercept = 25.9047
slope = 2.8420
