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.

The answer is -1 1/2
Step-by-step explanation:
This problem doesn't have that much steps.
What you do is this.
Step 1: You have 2 7/8 and 4 3/8 now turn it into a improper faction it will look like this 23/8 -35/8
Step 2: Now minus 23/8 and 35/8 23-35= -12 and the 8's stay the same now it will look like this -12/8
Step 3: Now see how many times 8 can go into -12 so -8 times 1= -8 now get from -8 to -12 that equals 4 so it will look like this -1 4/8 that can be simplify by 4 because 4x1=4 And 4x2=8 Now your answer is -1 /12
Answer: They made 6 three point shots.
Step-by-step explanation:
Make your equation
(((6x1)+(27x2)+(3x)=78
Simplify
(6+54+3x=78)
60+3x=78
Subtract from both sides
3x=18
Divide from both sides
x=6
