The answer would be the third option because the first two have improper word placement. Read the first two sentences out loud and you will notice how weird they sound. The third option sounds very clear which is why it is the correct option.

Hi,
y+2=-1/2(x-2) ==>y=-x/2-1.
The slope (if this is right) : 2*s=-1==>s=-1/2

Decrease 960 ML by 33 and one-third%

AnnZ [28]

To do this, first, find the decimal of 1/3. You will divide 1 by 3. This equals .333333333(goes on forever). Put a repeating bar over the first 3 to show that it goes on forever (put this: - over the .3) Now divide to find out how much you will need to subtract by. 960*33.3(with - over .3)=28.8. Subtract 28.8 from 960 (960-28.8=931.2) 931.2 is the answer.

One of the tallest living men has a height of 236 cm. One of the tallest living women is 224 cm tall. Heights of men have a mean

Roman55 [17]

Answer:

A. The woman is relatively taller because the z score for her height is greater than the z score for the man's height.

Step-by-step explanation:

Whoever has the highest z-score, is taller relative to the population of the same gender.

The z-score of a value X in a set with mean $\mu$ and standard deviation $/sigma$ is given by:

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

Solution:

Heights of men have a mean of 170 cm and a standard deviation of 6 cm. One of the tallest living men has a height of 236 cm. So the z-score of his height is:

$Z = \frac{X - \mu}{\sigma} = \frac{236-170}{6} = 11$

Heights of women have a mean of 161 cm and a standard deviation of 5 cm.

One of the tallest living women is 224 cm tall. The z-score of the women's height is

$Z = \frac{X - \mu}{\sigma} = \frac{224-161}{5} = 12.6$

The women has a higher z-score, so she is relatively taller.

The correct answer is A
