Fraction simplified:33/40
Decimal:0.825
Percent:82.5
Answer:
The correct answer to the question is
e. If is likely that between 35% and 41% percent of the driving population would be willing to pay higher gas prices to protect the environment.
Step-by-step explanation:
The margin of error expresses the number of percentage points of error is contained within survey result. A large error margin therefore reduces the level of dependence on a given statistic. The margin of error describes the expected variation between the statistic sample and the real population value.
In the question, the option
e. If is likely that between 35% and 41% percent of the driving population would be willing to pay higher gas prices to protect the environment , clearly depicts the definition of margin of error as it shows the expected variance from te real population
Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6
Step-by-step explanation:
Given equation of line is:
The coefficient of x is the slope of the line so the slope of given line is: -0.75
As parallel lines have equal slopes so the required equation of line will have the same slope.
The slope-intercept form is:
Putting the value of the slope
To find the value of b, putting the point in the equation
Putting the values of m and b, we get
Hence,
Equation of line parallel to y = -0.75x that passes through (8,0) is: y = -0.75x-6

Answer:
Ok, primero, como lo deducimos gráficamente?
Sigamos estos pasos.
Dibujemos en una recta, la distancia entre el punto 0 soles y el precio de la bicicleta = 200 soles.
200 soles representa el 100%.
Ella lo quiere vender al 80% (o le quiere restar el 20%).
Entonces, con una regla, medir la distancia entre 0 soles y 200 soles.
Dividir esa cantidad por 10. (cada una de estas cantidades va a representar un 10%)
Multiplicar eso por 8.
Esa cantidad es el equivalente al 80% del precio de la bicicleta.
Abajo hay un dibujo donde se ve el método.
Una forma mas matemática de resolverlo es:
200 soles = 100%.
x soles = 80%
x es el precio al que ella va a vender la bicicleta:
Veamos el cociente de esas dos ecuaciones:
200/x = 100%/80%
x = 200*(80%/100%) = 160
Ella vendería la bicicleta en 160 soles.
