On a standardized exam, the scores are normally distributed with a mean of 165 and astandard deviation of 40. Find the z-score o

vladimir1956 [14]

The Z-score is calculated by the formula below

$\begin{gathered} z-score=\frac{(x-\mu)}{\sigma}_{} \\ \mu=\operatorname{mean} \\ \sigma=s\tan dard\text{ deviation} \\ x=\text{score} \end{gathered}$

Step 2: Substitute the given parameters in the formula

$\begin{gathered} z-\text{score}=\frac{145-165}{40} \\ Z=-\frac{20}{40} \\ Z=-\frac{1}{2} \\ Z=-0.5 \end{gathered}$

Hence, the z-score of a person who scored 145 on the exam is -0.5

Answer:

(-7.5, 3.5)

Step-by-step explanation:

$midpoint \: = ( \frac{x1 + x2}{2} \: , \: \frac{y1 + y2}{2} )$

$= ( \frac{ ( - 5) + ( - 10)}{2} , \frac{(5) + (2)}{2} )$

$= ( \frac{ - 15}{2} , \frac{7}{2} )$

$= ( - 7.5,3.5)$
