Which of the following statements about shapes of histograms is true? a. A histogram is said to be symmetric if, when we draw a vertical line down the center of the histogram, the two sides are identical in shape and size.
b. A negatively skewed histogram is one with a long tail extending to the left.
c. A positively skewed histogram is one with a long tail extending to the right.
d. All of these choices are true

d. all of these choices are true

Step-by-step explanation:

Histograms have 3 outstanding shapes:

1. they are syymetric:

this is to say that from the middle of the histogram if you cut it into two or half, each side is an exact close representation of the other side.

2. they are positively skewed to the right:

That is it has a long tail that goes off towards the right.

3. they are negativly skewed to the left:

They have a long tail that goes off to the left.

therefore from the question option d is the best answer since a, b, c describes the shape of a histogram.

y=sec x is the correct answer
