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.

kirza4 [7]

Answer:

The total price is $5720

Step-by-step explanation:

According to the given statement a bedroom set lists for $7,000 and carries a trade discount of 20 percent. Freight (FOB shipping point) of $120 is not of the list price.

A bedroom lists for = $7000

Discount = 20% = 0.2

Now multiply 7000 by 0.2 = 7000* 0.2 = 1400

It means the discount value was $1400

Now subtract 1400 from 7000 = 7000 - 1400 = $5600

Now to get the total price add 5600 with 120 we get,

$5600+120 = $5720

Thus the total price is $5720 .....
