Answer 108

Step-by-step explanation:

So first you would subtract 14 from 36. 36-14=12, then you would multiple by 9. 9 times 12 = 108.

8_murik_8 [283]

Answer:

IQR = 8

Step-by-step explanation:

The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁

We require the data arranged in ascending order and to find the median Q₂

The median is the middle value of the data arranged in ascending order.

8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22

↑ Q₂

The upper quartile is the middle value of the data to the right of the median

13, 15, 17, 18, 22

↑ Q₃

The lower quartile is the middle value of the data to the left of the median

8, 9, 9, 9, 10

↑ Q₁

IQR = Q₃ - Q₁ = 17 - 9 = 8

If Logx (1 / 8) = - 3 / 2, then x is equal to

snow_tiger [21]

Answer:

Let's solve!

Step-by-step explanation:

$logx^{\frac{1}{8} } = -\frac{3}{2}$

$then$

$10^{-\frac{3}{2}} = x^{\frac{1}{8} }$

$(10^{-\frac{3}{2} })^{8} = (x^{\frac{1}{8} })^{8}$

$x = 10^{3*4} = 10^{-12}$

$x= 10^{-12}$

If the equation looks like this, then it has the solution

$x= 10^{-12}$

Another answer is

√x = 2 or x = 4

I hope this helps!
