Two students, Stephanie and Maria, want to find out who has the higher GPA when compared to each of their schools. Stephanie has
Lubov Fominskaja [6]

Answer:

z score for Maria is higher than Stephanie

Step-by-step explanation:

for Stephanie

GPA = 3.85

Mean of her school GPA = 3.1

Standard deviation = 0.4

Z =\frac{x -\mu}{\sigma}

  = \frac{3.85 -3.1}{0.4}

Z =1.875

for Maria

GPA = 3.80

Mean of her school GPA = 3.05

Standard deviation = 0.2

Z =\frac{x -\mu}{\sigma}

  = \frac{3.80 -3.05}{0.2}

Z =3.750

therefore z score for Maria is higher than Stephanie

Use the substitution method to solve the following system of equations:
Ivenika [448]
Using the first equation:
4x = y + 3   --->   y = 4x - 3
We then substitute this into the second equation:
7x - 9(4x-3) = -2   --->   7x - 9x + 27 = -2   --->   -2x = -29   --->   x = 14.5
