Answer:

<u>Descriptive</u> statistics consists of organizing and summarizing information​ collected, while <u>inferential</u> statistics use methods that generalize results obtained from a sample to the population and measure the reliability of the results.

Step-by-step explanation:

By definition, descriptive statistics summarize a given data set using measures of central tendency and measures of variability.  

Measures of central tendency include:

  • mean.
  • median.
  • mode.

Measures of variability include:

  • standard deviation.
  • variance.
  • the minimum and maximum variables.

By definition, inferential statistics are used to make generalizations about a population from data samples.

For example, you might ask a sample of 100 people if they like shopping. You could make a bar chart of yes or no answers (descriptive statistics) or you could use your research and then, reason which is the percentage of the population that likes shopping (inferential statistics).

A triangle has a base length of 3ac2 and a height 5 centimeters more than the base length. Find the area of the triangle if a =
pochemuha

Answer:

45750 cm²

Step-by-step explanation:

<h3>Area of triangle:</h3>

    a = 4 and c = 5

 base length = 3ac²

                      = 3 * 4 * 5 * 5

                     = 300 cm

    height = 5 cm more than the base length

               = 300 + 5

               = 305 cm

      \sf \boxed{\bf Area \ of \ triangle = \dfrac{1}{2}*base \ length * height}

                                    \sf =\dfrac{1}{2}*300*305\\\\= 150 * 305\\\\= 45750 \ cm^2

If you wanted to find the mean height of students in an elementary school,
Kryger [21]

It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.

Choosing a group would provide the average height for that group, not the entire primary.

Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.

PRICES The Consumer Price Index (CPT) gives the relative price for a fixed set of goods and services. The CPI from
slavikrds [6]

Using function concepts, it is found that the turning points of the graph are:

  • November 2000, when it goes from increasing to decreasing.
  • December 2000, when it goes from decreasing to increasing.
  • June 2001, when it goes from increasing to decreasing.

In a graph:

  • A function is increasing if it is <u>pointing upwards.</u>
  • If it is <u>pointing downwards,</u> it is decreasing.
  • A turning point is when the function changes from <u>decreasing to increasing or vice-versa</u>.

In this problem:

  • Initially, the function is increasing.
  • In month 3, that is, November 2000, it starts to decrease, thus, in November 2000, we have a<u> turning point.</u>
  • The next month, that is, December 2000, it starts to increase again, so it is another <u>turning point</u>.
  • It increases until month 9, which is June 2001, when it starts to decrease, being the <u>final turning point.</u>

a circle with circumference 20 has an arc with a 72 degrees central angle. what's the length of the arc
Ugo [173]

Answer:

4 units.

Step-by-step explanation:

Let's use a ratio

72 : 360

8  :  40

1   :   5

The arc is \frac{1}{5} of the total circumference.

\frac{1}{5} *20=4

The arc length is 4
