Which equation represents a line parallel to 3x − 8y = 12?

BaLLatris [955]2 years ago

Answer: I don’t know the choices, but a line parallel to that equation must have a slope of 3/8 when simplified into slope-intercept form.

Slope-intercept form: y = mx + b

Solving:
3x - 8y = 12
-8y = -3x + 12
y = 3/8x - 1 1/2

Which of the following is being constructed in the image.
Sliva [168]

Answer:

  3. a line perpendicular to a given line through a point not on the line

Step-by-step explanation:

The point not on the line suggests that choices 1 and 3 are possibilities. The fact that the dotted line is not parallel (and is perpendicular) to the solid line suggests that choice 3 is applicable and choice 1 is not.

The short arcs are equidistant from the end points of the chord that intercepts the larger arc. Hence the line through the crossing point of the short arcs and the point on the other side of the line will be the perpendicular bisector of the chord, and will be perpendicular to the solid line. Creating that perpendicular is likely the purpose of the construction.

A statistics professor receives an average of five e-mail messages per day from students. Assume the number of messages approxim
kaheart [24]

Answer:

The probability that on a randomly selected day the statistics professor will have five messages is 0.1755.

Step-by-step explanation:

Let the random variable <em>X</em> represent the number of e-mail messages per day a statistics professor receives from students.

The random variable is approximated by the Poisson Distribution with parameter <em>λ</em> = 5.

The probability mass function of <em>X</em> is as follows:

P(X=x)=\frac{e^{-5}\cdot 5^{x}}{x!};\ x=0,1,2,3...

Compute the probability that on a randomly selected day she will have five messages as follows:

P(X=5)=\frac{e^{-5}\cdot 5^{5}}{5!}

               =\frac{0.006738\times 3125}{120}\\\\=0.17546875\\\\\approx 0.1755

Thus, the probability that on a randomly selected day the statistics professor will have five messages is 0.1755.
