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.
(xy+4y)/x = (3x-2)/x
(y+4y)/x = (3x-2)/x divide both side by x
5y /x = (3x-2)/x
5y= 3x-2 Mult by x both side
y= (3x-2)/5
Answer:
The chosen topic is not meant for use with this type of problem. Try the examples below.
|2y| = 3 + 2
− 2 (y+2) = 2 −y
x−2=4
Step-by-step explanation:
5x^2= 2205
Divide both sides by 5
x^2=441
Find the square root of both sides
x= 21
