Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.

Step-by-step explanation:

  • It is imperative to create a data in a tabular column before analyzing.
  • Once the data is created use tally marks or frequency distribution.
  • Frequency distribution helps the data to provide occurrence of event.
  • Very important to number which is a counting numbers are discrete.
  • Continuous of data are ones which are in decimal.
  • Descriptive statistics is the 1st level of Statistics.
  • It finds, where the data stands. Minimum, Maximum is understandable.
  • Range is at what level data is expanded.

Suppose that Y varies directly with X andY equals 12 when X equals -2 what is X when Y equals -6
VLD [36.1K]

Answer:

x=1

Step-by-step explanation:

A direct variation equation has the following format:

y=kx

Where k is a constant.

We know that y is 12 when x is -2. Thus, substitute:

12=-2k

Divide both sides by -2:

k=-6

So, our direct variation equations is:

y=-6x

To find what x is when y equals -6, substitute in -6 for y:

-6=-6x

Divide both sides by -6:

x=1

So, our answer is 1 :)

A portfolio is efficient if which of the following is true?
fgiga [73]

Answer:

In economics, a portfolio is a term for a specific set of stocks, bonds, shares, and other securities owned by an investor. In general, the investor seeks to compile and diversify a portfolio of securities that offers maximum profitability and at the same time is diverse, in order to minimize possible risks. In general, these types of portfolios are considered efficient, as they do not leave the investment risk tied to a single factor. However, these two goals often go against each other, so the composition of the portfolio means a certain compromise.
