<h3>Answer:</h3>

$\frac{1}{9}$

<h3>Step-by-step explanation:</h3>

We know that $x=-2$ , so substitute that into the equation. $y=3^{-2}$

With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, $x^{-y}=\frac{1}{x^y}$ . This makes our equation: $y=\frac{1}{3^2}$

Finally, simplify the exponent. $y=\frac{1}{9}$

g At a certain gas station, 30% of all customers use the restroom. What is the probability that, out of the next 10 customers, (

Kruka [31]

Answer:

$P(x=4) = 0.200$

Step-by-step explanation:

Given

$n=10$ --- selected customers

$x = 4$ --- those that are expected to use the restroom

$p =30\% = 0.30$ --- proportion that uses the restroom

Required

$P(x = 4)$

The question illustrates binomial probability and the formula is:

$P(x) = ^nC_x * p^x * (1 - p)^{n - x}$

So, we have:

$P(x=4) = ^{10}C_4 * (0.30)^4 * (1 - 0.30)^{10 - 4}$

$P(x=4) = ^{10}C_4 * (0.30)^4 * (0.70)^6$

$P(x=4) = 210* (0.30)^4 * (0.70)^6$

$P(x=4) = 0.200$

If J/24 = K, then J/6 =

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

$\frac{J}{24}$ = K ( multiply both sides by 24 to clear the fraction )

J = 24K ( divide both sides by 6 )

$\frac{J}{6}$ = 4K
