Answer:
Step-by-step explanation:
If you want to factor
, you could throw that into the quadratic formula with a = 1, b = 11 and c = 0, but the easier thing to do is to factor out what's common in those 2 terms. m is common, so when we factor it out:
That's the factored form.
By the Zero Product Property, either
m = 0 or m + 11 = 0.
So the 2 solutions to this are
m = 0 or m = -11
Not sure how far you need to go with this.
The construction is the construction of the Perpendicular bisector.
<h3>How to illustrate the information?</h3>The steps for the construction of perpendicular bisectors are as follows:
Open the compass more than half of the distance between A and B, and scribe arcs of the same radius centered at A and B.
Call the two points where these two arcs meet X and Y. Draw the line between X and Y.
So, the point where this line meets the line segment; M is called the mid point and the line XY is the perpendicular bisector of the line AB.
The figure is a construction of perpendicular bisector.

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.
<h3>¿Qué es la media?</h3>En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.
Calcular la media:
Usando la formula anterior, calculemos la media:
- 16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7
El valor de la media es 18.7, al respecto se puede observar que:
- Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.
- Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.
