James states that quadrilateral

mr_godi [17]

Using the distance formula,

$AD=\sqrt{(-1-3)^{2}+(-3-(-4))^{2}}=\sqrt{17}\\\\BC=\sqrt{(5-9)^{2}+(1-0)^{2}}=\sqrt{17} \\\\\therefore \overline{AD} \cong \overline{BC}$

$AB=\sqrt{(-1-5)^{2}+(-3-1)^{2}}=\sqrt{52}=2\sqrt{13}\\\\CD=\sqrt{(9-3)^{2}+(0-(-4))^{2}}=\sqrt{52}=2\sqrt{13}\\\\\therefore \overline{AB} \cong \overline{CD}$

Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.

According to the United States Health and Human Services, the mean height for Americans is 1.757 meters for men and 1.618 meters

Alchen [17]

Answer:

Her z-score is 2.03.

Step-by-step explanation:

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

Michelle’s height is 1.758 meters. What is her z-score?

Michelle's is a woman.

The average height of women is $\mu = 1.618$ and the standard deviation is $\sigma = 0.069$

This is Z when X = 1.758. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{1.758 - 1.618}{0.069}$

$Z = 2.03$

Her z-score is 2.03.
