Ok
You look at how many ‘x’ there are then you add them together 6x+3x+x+10+40=180
I think you can take it from here?

Answer:

C) $\frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}$

Step-by-step explanation:

Given fractions:

$\frac{2}{4}, \frac{4}{5}, \frac{7}{10},\frac{2}{3}$

To arrange the fractions from least to greatest.

Solution:

In order to arrange the fractions from least to greatest, we need to make the denominators common by taking LCD.

LCD of 4,5,10,3 can be found using their multiples.

4= 4,8,12,16,20,24,28,32,36,40,.........60

5= 5,10,15,20,25,30,.........60

10= 10,20,30,40,50,60

3= 3,6,9..........................60

So, 60 is the LCD.

Making the denominators common by multiplying same numbers to numerator and denominator.

$\frac{2}{4}=\frac{2\times 15}{4\times 15}=\frac{30}{60}$

$\frac{4}{5}=\frac{4\times12}{5\times 12}=\frac{48}{60}$

$\frac{7}{10}=\frac{7\times 6}{10\times 6}=\frac{42}{60}$

$\frac{2}{3}=\frac{2\times 20}{3\times 20}=\frac{40}{60}$

Comparing the numerators we can arrange the fractions.

$\frac{2}{4}, \frac{2}{3}, \frac{7}{10}, \frac{4}{5}$

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
