Mai makes her favorite shade of green paint by using 5 cups of blue paint for every 3 cups of yellow paint. Priya makes her favo

Lelechka [254]

Answer:

Priya

Step-by-step explanation:

Mai= 5:3 Priya=7:5

Mai= 15:15 Priya=21:15

The ratios above are blue:yellow so Priya's shade has more of a blue tint because it is 21:15 and Mai's is 15:15 so it is evenly spread.

Simplify the expression ((81y^-8)/(16x^20))^-1/4

Darina [25.2K]

$\bf ~~~~~~~~~~~~\textit{negative exponents}
\\\\
a^{-n} \implies \cfrac{1}{a^n}
\qquad \qquad
\cfrac{1}{a^n}\implies a^{-n}
\qquad \qquad 
a^n\implies \cfrac{1}{a^{-n}}
\\\\
-------------------------------$

$\bf \left( \cfrac{81y^{-8}}{16x^{20}} \right)^{-\frac{1}{4}}\implies \left( \cfrac{16x^{20}}{81y^{-8}} \right)^{\frac{1}{4}}\implies \left( \cfrac{2^4x^{20}}{3^4y^{-8}} \right)^{\frac{1}{4}}
\\\\\\
\textit{and now we'll distribute the exponent}\qquad \left( \cfrac{2^{4\cdot \frac{1}{4}}x^{20\cdot \frac{1}{4}}}{3^{4\cdot \frac{1}{4}}y^{-8\cdot \frac{1}{4}}} \right)
\\\\\\
\cfrac{2^1x^5}{3^1y^{-2}}\implies \cfrac{2^1x^5y^2}{3^1}\implies \cfrac{2x^5y^2}{3}$

Assume that you select 2 coins at random from 8 coins: 5 dimes and 3 quarters.

Vilka [71]

If the coins are selected without replacement, the probability of 2 dimes is: $\frac{5}{8}\times\frac{4}{7}=\frac{5}{14}$
The answer is 5/14.
Using the formula for a hypergeometric distribution, we get:
$P(2\ dimes)=\frac{5C2\times3C0}{8C2}=\frac{5}{14}$
