Answer:
probability that Marnie and Noomi are both selected=0.1
Step-by-step explanation:
A group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas.
the possibility of selecting 2 from 5 manages is 5C2 ways
![5C2= \frac{5!}{2!(5-2)!} =10](https://tex.z-dn.net/?f=5C2%3D%20%5Cfrac%7B5%21%7D%7B2%21%285-2%29%21%7D%20%3D10)
There is only one choice of selecting Marine and Noomi from 5 managers
So probability of selecting Marine and Noomi is
![\frac{1}{10} =0.1](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D%20%3D0.1)
Answer:
Step-by-step explanation:
Let m = maracas
c = claves
d = djembe drums
12m + 6c + xd = $326

Answer:
![\dfrac{1}{27}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B27%7D)
Step-by-step explanation:
![n^{-\frac{2}{3}}=9](https://tex.z-dn.net/?f=n%5E%7B-%5Cfrac%7B2%7D%7B3%7D%7D%3D9)
Rewrite:
![\dfrac{1}{\sqrt[3]{n^2}}=9\\\\9\sqrt[3]{n^2}=1](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B%5Csqrt%5B3%5D%7Bn%5E2%7D%7D%3D9%5C%5C%5C%5C9%5Csqrt%5B3%5D%7Bn%5E2%7D%3D1)
Cube both sides:
![729n^2=1](https://tex.z-dn.net/?f=729n%5E2%3D1)
Divide both sides by 729:
![n^2=\dfrac{1}{729}](https://tex.z-dn.net/?f=n%5E2%3D%5Cdfrac%7B1%7D%7B729%7D)
Take the square root of both sides:
![n=\sqrt{\dfrac{1}{729}}=\dfrac{1}{27}](https://tex.z-dn.net/?f=n%3D%5Csqrt%7B%5Cdfrac%7B1%7D%7B729%7D%7D%3D%5Cdfrac%7B1%7D%7B27%7D)
Hope this helps!
