So B) has all the requirements

The vertical line in the box represents the mean which if you add all the numbers and divide by 15 you get 17 and since no other whisker box plot doesn't have 17 as its mean B is the only logical answer

Answer:

y = 20

Step-by-step explanation:

$9 - \sqrt{y - 4} = 5$

<h3>i) move 9 to the right-hand side and change its sign</h3>

$- \sqrt{y - 4} = 5 - 9$

<h3>ii) calculate the difference</h3>

$- \sqrt{ y - 4} = - 4$

<h3>iii) change the signs on both sides of the equation</h3>

$\sqrt{y - 4} = 4$

<h3>iv) square both sides of the equation</h3>

$( \sqrt{y - 4} ) {}^{2} = 4 {}^{2}$

$y - 4 = 4 {}^{2}$

$y - 4 = 16$

<h3>v) move -4 to the right-hand side and change its sign</h3>

$y = 16 + 4$

<h3>vi) add the numbers</h3>

$y = 20$

Liliana used 444 dark power crystals to raise 141414 zombie soldiers. She wants to know how many zombie soldiers (z)(z)left pare

Mariulka [41]

Question is bit incorrect, Correct question is given below.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answer:

Liliana can raise 35 zombie soldiers.

Step-by-step explanation:

Let the number of zombie soldiers raised by 10 dark power crystals be 'z'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

$\frac{z}{10}=\frac{14}{4}$

Multiply 10 on both the sides, we get

$z=\frac{14}{4}\times 10 = 35$

Hence, Liliana can raise 35 zombie soldiers.
