Are the grades shown in the math class below normally distributed? Explain your answer.
IgorLugansk [536]

Since the histogram is not symmetric, the grades shown in the math class below are not normally distributed.

<h3>When does a histogram represent a normal distribution?</h3>

A histogram represents a normal distribution if it symmetric.

In this problem, we have that:

  • 57% of the grades are on the left tail.
  • 25% of the grades are on the center.
  • 18% are on the right tail.

Since the percentages at the tails are different, the histogram is not symmetric, and  the grades shown in the math class below are not normally distributed.

Which composition of transformations maps figure EFGH to figure E"F"G"H"?
Lady bird [3.3K]

The transformations would map EFGH to {\text{E''F''G''H''}} is a reflection across line k followed by a translation down. Option (a) is correct.

Further explanation:

Given:

The compositions of transformations from EFGH to {\text{E''F''G''H''}} are as follows,

(a). A reflection across line k followed by a translation down.

(b). A translation down followed by a reflection across line k.

(c). A {180^ \circ } rotation about point G followed by a translation to the right.

(d). A translation to the right followed by a {180^ \circ } rotation about point G.

Explanation:

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Rotation is defined as a movement around its own axis. A circular movement is a rotation.

The transformations would map EFGH to {\text{E''F''G''H''}} is a reflection across line k followed by a translation down. Option (a) is correct.

Option (a) is correct.
