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: Option D) 3 x 5 + 4 x 2
Step-by-step explanation:
- Since a dozen muffins costs $5.
Buying 3 dozen muffins means (3 x $5)
- Since Large bottles of juice cost $2.
The cost of 4 large bottles of juice is (4 x $2)
Hence, the total cost is (3 x $5) + (4 x $2)
= $15 + $8
= $23
Now, you'll notice that "3 x 5 + 4 x 2" gives 23.
Thus, it is the only expression that could be used to find the total cost.
