SAT scores have a mean of 1026 and a standard deviation of 209. ACT scores have a mean of 20.8 and a standard deviation of 4.8.
Y_Kistochka [10]

Answer:

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Step-by-step explanation:

Mean SAT scores = 1026

Standard Deviation = 209

Mean ACT score = 20.8

Standard Deviation = 4.8

We are given SAT and ACT scores of a student and we have to compare them. We cannot compare them directly so we have to Normalize them i.e. convert them into such a form that we can compare the numbers in a meaningful manner. The best way out is to convert both the values into their equivalent z-scores and then do the comparison. Comparison of equivalent z-scores will tell us which score is higher and which is lower.

The formula to calculate the z-score is:

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

Here, μ is the mean and σ is the standard deviation. x is the value we want to convert to z score.

z-score for junior scoring 860 in SAT exam will be:

z=\frac{860-1026}{209}=-7.59

z-score for junior scoring 16 in ACT exam will be:

z=\frac{16-20.8}{4.8}=-1

The z-score for SAT exam of junior is much small than his ACT score. This means he performed well in his ACT exam and performed poor in his SAT exam.

Write the following as an algebraic expression. Then simplify.
Ratling [72]

The sum of three even consecutive integers if the first integer is y will be 3y + 6.

First integer = y

Second integer = y + 2

Third integer = y + 4

Therefore, based on the expressions given above, the sum of the three integers will be:

= y + y +2 + y + 4

= 3y + 6

Therefore, the sum will be 3y + 6.
