Mi hermano ha ganado un dinero <em>devengado</em> de 8835 pesos en 15 días.

En esta pregunta debemos determinar el dinero <em>devengado</em> por un período de 15 días a partir de una tasa diaria <em>constante</em>. Esa cantidad es igual al producto de la tasa diaria <em>constante</em>, en pesos por día, y el número de días <em>trabajados</em>, en días:

x = 589\,\frac{\$}{dia}\times 15\,dias

x = 8835\,\$

Mi hermano ha ganado un dinero <em>devengado</em> de 8835 pesos en 15 días.

The equivalent expression is 7^{2}.

We have the following expression -

\frac{7^{-3} }{7^{-5} }

We have to find its equivalent value.

<h3>What is the equivalent expression of the following expression-</h3>

f(x, y) =\frac{A^{x} }{A^{y} }

In order to divide two exponents with same base, we use the 'Quotient property of exponents.

The equivalent expression can be written as -

f(x, y) = A^{x} A^{-y} = A^{x-y}

In the question given we have -

\frac{7^{-3} }{7^{-5} }

Using the property discussed above -

7^{-3}\;7^{5} = 7^{-3+5} = 7^{2}

Hence, the equivalent expression is 7^{2}.

The operating costs for each machine for one day have an unknown distribution with mean 1610 and standard deviation 136 dollars.
BabaBlast [244]

Answer:

20.27

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means with size n of at least 30 can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}

Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?

This is s when \sigma = 136, n = 45. So

s = \frac{136}{\sqrt{45}} = 20.27

So the correct answer is:

20.27

The lengths of the sides of a triangle are in the extended ratio 8 : 9 : 10. The perimeter of the triangle is 108cm. What are th
belka [17]

Answer:

32, 36, 40

Step-by-step explanation:

8x + 9x + 10x = 108

27x = 108

x = 4

4 × 8 = 32 - 1st side

4 × 9 = 36 - 2nd side

4 × 10 = 40 - 3rd side
