In the histogram, we are given heights on the x - axis and quantities on the y - axis. We want to know how many trees are less than 24 meters tall.

There are the following groups, and the number of trees in each:

0-4 0

4-8 1

8-12 2

12-16 2

16-20 4

20-24 6

24-..... STOP (Because this includes 24)

We total up our frequencies above, 1 + 2 + 2 + 4 + 6 = 15.


Thus there are 15 trees --- Choice C -- less than 24 meters tall.

Resuelve las siguientes ecuaciones y luego verifica<br> A-)3x +1=7<br> B-)2a-2=1+3a
jarptica [38.1K]

Answer:

A) x=2

B) a=-3

Step-by-step explanation:

La primera ecuación dada es,

A) 3x + 1 = 7

Reste 1 de ambos lados, tenemos

3x +1-1=7-1

\Rightarrow 3x=6

Dividir por 3 (ya que 3 es un número distinto de cero) de ambos lados, tenemos

\frac{3x}{3}=\frac {6}{3}

\Rightarrow x=2

Ahora, compruebe si x = 2 es la solución correcta o no.

El lado izquierdo de la ecuación dada es 3x + 1.

Ponga x = 2, tenemos

3\times2+1=7

Que es igual al lado derecho de la ecuación dada.

Por tanto, x = 2 es la solución correcta.

La segunda ecuación es

B) 2a-2=1+3a

Reste 3a de ambos lados, tenemos

2a-2-3a=1+3a-3a

\Rightarrow -a-2=1

Suma 2 de ambos lados, tenemos

-a-2+2=1+2

\Rightarrow -a=3

Multiplica por -1 (como -1 es un número distinto de cero) de ambos lados, tenemos

-a\times (-1)=3\times(-1)

\Rightarrow a=-3

Ahora, verifique si a = -3 es la solución correcta o no

El lado izquierdo de la ecuación dada es 2a-2.

Ponga a = -3, tenemos

2\times(-3)-2=-8

El lado derecho de la ecuación dada es 1 + 3a.

Ponga a = -3, tenemos

1+3\times(-3)=-8.

Aquí, al poner a = -3, el valor del lado izquierdo es igual al valor del lado derecho.

Por tanto, a = -3 es la solución correcta.
