Answer:

Mean = 5.45

Step-by-step explanation:

Given

\begin{array}{cc}{x} & {f} & {0} & {1} & {1} & {2} \ \\ {3} & {1} & {4} & {2} & {5} & {6}  & {6} & {7} & {7} & {6} & {8} & {5}\ \end{array}

Required

Calculate the mean

Mean is calculated as:

Mean = \frac{\sum fx}{\sum f}

So, we have:

Mean = \frac{0*1 + 1*2 + 2*1 + 3*1+4*2+5*6+6*7+7*6+8*5}{1+2+1+1+2+6+7+6+5}

Mean = \frac{169}{31}

Mean = 5.45161290323

Mean = 5.45 -- approximated

6. Complete la tabla con el número 4.956: Dígito Valor posicional Notación estándar Notación en potencia De esta forma el número
Rzqust [24]

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹
