Answer:

  144 m²

Step-by-step explanation:

The total surface area is the sum of the areas of the four triangular faces.

Three of them have a base of 10 and a height of 6.7. The fourth has a base of 10 and a height of 8.7. Here, we'll show the sum in one expression, so we can do some simplification.

  A = ∑(1/2)bh = (1/2)(10)(6.7) +(1/2)(10)(6.7) +(1/2)(10)(6.7) +(1/2)(10)(8.7)

  = (1/2)(10)(3·6.7 +8.7) = 5(28.8) = 144 . . . . square meters

En un examen calificado del 0 al 10, 3 personas obtuvieron 5 de nota, 5 personas obtuvieron 4 de nota, y 2 personas obtuvieron 3
Nastasia [14]

Answer:

Media = 4.1

Mediana = 4

Moda = 4

Step-by-step explanation:

3 personas obtuvieron 5 puntos

5 personas obtuvieron 4 puntos

2 personas lograron 3 puntos

a. La media se da como:

Media = suma total de marcas / número de personas

Por lo tanto, la media será:

M = \frac{((3 * 5) + (5 * 4) + (2 * 3)}{10}\\ \\M = \frac{15 + 20 + 6}{10} \\\\M = \frac{41}{10}\\ \\M = 4.1

b. Para obtener la mediana, tenemos que organizar los términos en consecuencia y encontrar el número en el medio.

3, 3, 4, 4, 4, 4, 4, 5, 5, 5

Como no hay un número único en el medio, la mediana es:

(4 + 4) / 2 = 8/2 = 4

c. La moda es el número que aparece más, y eso es 4

What is an equation for the line with slope 2/3 and 7-intercept 9? 30 points to whoever answers this correctly and gets brainlie
Annette [7]

The equation of the line is y = \frac{2}{3} x + 9

Step-by-step explanation:

The equation of a line in slope-intercept form is y = m x + b, where

  • m is the slope of the line
  • b is the y-intercept ⇒ the value of y when x = 0

∵ The line has a slope \frac{2}{3}

∴ m = \frac{2}{3}

∵ The y-intercept is 9

∴ b = 9

- Substitute the values of m and b in the form of the equation below

∵ y = m x + b

∴ y = \frac{2}{3} x + 9

The equation of the line is y = \frac{2}{3} x + 9
