01. Se tienen los angulos consecutivos AOB, BOC y COD. se cumple m&amp; AOC=125° m <br>​
Citrus2011 [14]

La diferencia entre los ángulos <em>AOB</em> y <em>COD</em> del sistema de tres ángulos <em>consecutivos</em> es igual a 25°.

La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°.

<h3>Cómo analizar tres ángulos consecutivos</h3>

Por la geometría Euclídea conocemos que un conjunto de ángulos cuando comparten entre cada par de ángulos vecinos comparten el mismo vértice y la misma semirrecta.

De acuerdo con el enunciado, tenemos las siguientes condiciones:

∠AOB + ∠BOC = 125°   (1)

∠BOC + ∠COD = 100°  (2)

Por (1) y (2) tenemos las siguiente identidad:

∠AOB - 25° = ∠COD

∠AOB - ∠COD = 25°

La diferencia entre los ángulos <em>AOB</em> y <em>COD</em> del sistema de tres ángulos <em>consecutivos</em> es igual a 25°. \blacksquare

En el segundo caso, tenemos el siguiente sistema:

∠AOB = ∠BOC + ∠COD     (3)

∠AOB + ∠BOC - ∠COD = 40°     (4)

Por (3) y (4) tenemos la siguiente identidad:

2 · ∠BOC = 40°

∠BOC = 20°

La medida del ángulo BOC pertenenciente al sistema de tres ángulos consecutivos es igual a 20°. \blacksquare

An inspector at a factory examines 320 drinking glasses, and 12 of them have defects. The inspector then examines 560 drinking g
fgiga [73]

Answer: 539 without defects

Step-by-step explanation: Im pretty sure we have to turn 12/320 into a percent, which is 0.0375, or 3.75%

So with that information, we need to find 3.75% of 560.

do 0.0375 x 560, which is 21.

21 are defects, so do 560 - 21 is 539.

What is the median value of the data set shown on the line plot?
LenaWriter [7]

Answer:

110

Step-by-step explanation:

you would have to place the values in a line in ascending order and cancel numbers on both sides until you only have one left in the center. If you have two left because the number of variables is even then add both and divide by two. That was the case here. Both middle numbers were 110

so...

110+110/2

220/2

110
