The student's current average score will be 69.2
Step-by-step explanation:
Let first test be TEST A: which is 20 of total and secures 62
Let second test be TEST B: which is 20 of the total marks and has secured 83.
Let third test be TEST C: which is 20 of total and has secured 91.
And now the TEST D which is 25 of total and has secured 88.
Therefore, by multipying across
= 12.4
= 16.6
= 18.2
=22
Now, by adding the scores to get the average score
We get, 69.2.
Answer:
C(-2) = -9
Step-by-step explanation:
Step 1: Define
C(x) = -3x² - 3x - 3
C(-2) = x = -2
Step 2: Substitute and Evaluate
C(-2) = -3(-2)² - 3(-2) - 3
C(-2) = -3(4) + 6 - 3
C(-2) = -12 + 6 - 3
C(-2) = -6 - 3
C(-2) = -9
