Considering that the data has no outliers, the mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

<h3>What measure should be used to describe the center of a data-set?</h3>

It depends if the data-set has outliers or not.

  • If it does not have outliers, the mean should be used.
  • If it has, the median should be used.

The dot plot gives the number of times each measure appears. Since there is no outliers, that is, all values are close, the mean should be used. It is given by:

M = (2 x 1 + 3 x 2 + 2 x 3 + 1 x 5 + 1 x 6 + 1 x 7)/(2 + 3 + 2 + 1 + 1 + 1) = 3.2 inches.

The mean of 3.2 inches should be used to describe the center of the data represented in this line plot.

The base of a solid oblique pyramid is an equilateral triangle with a base edge length of 18 inches What is the height of the tr
ExtremeBDS [4]
The height of the triangular base of the pyramid is calculated through the equation,
                                        h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of  x is 30°. Substituting,
                                        h = (cos 30°)(18 in)
                                        h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.

Joelle would like to tip her hairdresser 20%. If her haircut was $38.00, which expression should she use to find the tip amount?
Vilka [71]
I pretty sure you would use x over 38.00 = 20 over 100 then cross multiply them
