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.

I NEED HELP ASAPPP!!!! It’s urgentttttt!!!!
Akimi4 [234]

Answer: (x - 2)² + (y - 14)² = 1

Step-by-step explanation:

<u>Concept:</u>

Here, we need to know the idea of the circle formula.

Circle formula: (x - h)² + (y - k)² = r²

Center = (h, k)

Radius = r

If you are still confused, please refer to the attachment below for a graphical explanation.

<u>Solve:</u>

Center = (2, 14)

Radius = 1

<em>Given formula</em>

(x - h)² + (y - k)² = r²

<em>Substitute the value into the formula</em>

(x - 2)² + (y - 14)² = (1)²

<em>Simplify</em>

(x - 2)² + (y - 14)² = 1

Hope this helps!! :)
