Answer:
Marcus score is 13.7, the mean is 12.89, and the standard deviation is 1.95, so I’ll do ( 13.7 – 12.89)/ 1.95, Since Marcus' z-score is 0.415. The area to the left of the z-score is 65.9% so therefore Marcus did scored better than 65.9% of the students. So Marcus needs to score 98% better of all the other students in order for him to receive an actual certificate.

Answer:
541 (484) 783, 437 (410) 642
Step-by-step explanation:
Required
Fill in the bracket
First, we generate a formula for the first sequence: 541 (484) 783
![484 = 2 * [783 - 541]](https://tex.z-dn.net/?f=484%20%3D%202%20%2A%20%5B783%20-%20541%5D)
![484 = 2 * [242]](https://tex.z-dn.net/?f=484%20%3D%202%20%2A%20%5B242%5D)
Using the same formula for the second sequence: 437 (?) 642
![x = 2 * [642 - 437]](https://tex.z-dn.net/?f=x%20%3D%202%20%2A%20%5B642%20-%20437%5D)
Where x represents the empty bracket
![x = 2 * [205]](https://tex.z-dn.net/?f=x%20%3D%202%20%2A%20%5B205%5D)
