Answer:
Statistical scores and rankings are useful because they provide quantitative figures that represent the student's level of understanding. These methods of ranking can give the observer an opportunity to quickly analyze results but they leave out other factors that are both quantifiable and non-quantifiable. For example, the data won't explicitly convey the time an individual studies but it is compelling to say that good scores and time studying gave a linear relationship. An example of something that is non-quantifiable is the experiences and past knowledge that can affect how well an individual understands and tests on a specific subject.
Respuesta:
El punto A(-3, 3) pertenece a la recta.
El punto B(0, -15) no pertence a la recta.
Explicación paso a paso:
Consideremos la siguiente ecuación de la recta en forma estandar.
-4x - y + 15 = 0
Para verificar si los puntos A y B pertencen a la recta, primero la transformaremos a la forma explícita.
-4x - y + 15 = 0
-4x + 15 = y
y = -4x + 15
El punto A(-3, 3), tiene coordenada x -3 y coordenada y 3. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.
y = -4(-3) + 15 = 3
El punto A(-3, 3) pertenece a la recta.
El punto B(0, -15), tiene coordenada x 0 y coordenada y -15. Reemplazaremos x en la ecuación de la recta y veremos si obtenemos el mismo valor de y.
y = -4(0) + 15 = 15
El punto B(0, -15) no pertence a la recta.
8 1/3 is equivalent to 25/3
2 2/3 is equivelent to 8/3
25/3-8/3 so you take away 8 from 25 and you get, 17 therefore, the answer is 17/3 or 5 2/3.
Hope this helped.
Have a nice day.
Median of 15
(14 + b) / 2 = 15
14 + b = 15 * 2
14 + b = 30
b = 30 - 14
b = 16
range of 30
c - a = 30....c = 30 + a
mean of 18
(a + 8 + 14 + 16 + 26 + c) / 6 = 18
(a + 8 + 14 + 16 + 26 + (30 + a)) / 6 = 18
(2a + 94) / 6 = 18
2a + 94 = 18 * 6
2a + 94 = 108
2a = 108 - 94
2a = 14
a = 14/2
a = 7
c - a = 30
c - 7 = 30
c = 30 + 7
c = 37
check..
7,8,14,16,26,37
median = (16 + 14) / 2 = 30/2 = 15 ...correct
range = 37 - 7 = 30...correct
mean(average) = (7 + 8 + 14 + 16 + 26 + 37) / 6 = 108/6 = 18...correct
so a = 7, b = 16, and c = 37
There should be 3 more of them.
6 vertically opposite
2 alternate interior angles
4 It is vertically opposite 2. I've forgotten how to name 4, but what I've said will prove it.
