Serggg [28]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The score of the student is  x = 779.42

Step-by-step explanation:

Generally we can mathematically represent the z-score as

         z =  \frac{x - Mean}{ stDev}

Here x is the score of the student

substituting 1045.7 for the Mean, 221.9 for the stDev and -1.2 for z we have  

          -1.2 =  \frac{x - 1045.7 }{ 221.9}

=>       -266.28 =  x -1045.7

=>     x  =  -266.28 + 1045.7

=>     x = 779.42
