AlekseyPX

Answer:

<em>La media aritmética es 2.3</em>

Step-by-step explanation:

<u>Average o Promedio</u>

El promerio, average, o valor medio es un valor representativo de un conjunto de datos y se calcula según la fórmula:

\displaystyle \bar x=\frac{\sum x_i}{n}

Donde xi es el valor de cada dato, y n es el número de datos.

Los datos presentados son:

1, 4, 1, 1, 4, 2, 3, 1, 4, 2

Nótese que hay un total de n=10 datos. Aplicamos la fórmula recordando que el símbolo Σ significa <em>sumatoria</em>:

\displaystyle \bar x=\frac{1+ 4+ 1+ 1+ 4+ 2+ 3+ 1+ 4+ 2}{10}

\displaystyle \bar x=\frac{23}{10}=2.3

La media aritmética es 2.3

How do u turn 2 3/4 into a improper faction
n200080 [17]

To turn a mixed number into an improper fraction, you have to multiply the denominator with the whole number and add the numerator to the result. The denominator doesn't change.

The denominator is 4. The whole number is 2. Multiply:

4 \times 2 = 8

The numerator is 3. Add that to the product of the denominator and whole number.

8+3=11

The denominator stays the same. The denominator is 4. Make it as a fraction(improper).

Numerator = 11 \\ Denominator = 4 \\ \\ Fraction: \frac{11}{4}

Your answer is \frac{11}{4}

Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cool
Rus_ich [418]
7.95 ÷ 1.06 = $7.50

This works as by dividing 7.95 by the percentage multiplier 1.06 it will give you the original amount.

An alternative method is to find out what 100% (7.95) is, then divide by 10 to find 10% and then divide by 10 again to find 1% and then multiply the 1% by 6 and subtracting the answer from 7.95.
