The given equation is the best line that approximates the linear
relationship between the midterm score and the score in the final exam.
- AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.
Reasons:
The given linear regression line equation is; 
= 25.5 + 0.82·
Where;
= Final exam score;
= The midterm score;
AJ score in the first test, = 90
AJ's actual score in the exam = 99
Required:
The value of AJ's residual
Solution:
By using the regression line equation, we have;
The predicted exam score, = 25.5 + 0.82 × 90 = 99.3
- The residual score = Predicted score - Actual score
∴ AJ's residual = 99.3 - 99 = 0.3
AJ's residual = 0.3
Therefore, the correct option is option E;

Answer:
151,515 * 555 = www
Step-by-step explanation:
Yeah so basically www is the total amount of dollars they have to buy 555 tickets. And each ticket costs $151,515, so like it's the cost per ticket times the amount of tickets to get the total amount of dollars
Answer:135
Step-by-step explanation:
bcs 45x60 is 2700 ÷20= 135
It’s 15 km. You need to take the root from 9^2 + 12^2 wich equals 15. You need to use pythagoras a^2 + b^= c^2
If your solving for x, you need to isolate/get the variable "x" by itself in the inequality:
-24 ≤ 3x - 9 First add 9 on both sides
-24 + 9 ≤ 3x - 9 + 9
-15 ≤ 3x Then divide 3 on both sides to get "x" by itself
-5 ≤ x [or x ≥ -5 if you prefer "x" to be on the left side]
