Multiply through by 16 to clear the fractions
10x + 32 = 57 ( subtract 32 from both sides )
10x = 25 ( divide both sides by 10 )
x = =

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:
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>:
La media aritmética es 2.3
Pythagoras Theorem:
Apply Pythagoras Theorem:
a² + 6² = 11²
a² = 11² - 6²
a²= 85
a = √85
a = 9.22 (nearest hundredth)
Answer: RT = 9.22 cm
