To solve your question, you add all of the measurements together, set them equal to 180, solve for x, and plug x back in for whichever angle they are asking for; in this case, they want angle R 

7x + 12x + 20 + 20x - 35 = 180
39x - 15 = 180
39x = 180 + 15
39x = 195
x = 5

Angle R = 12x + 20
12(5) + 20
60 + 20
80

___________ Qualitative Inferential Descriptive Quantitative statistics consists of organizing and summarizing information​ coll
Alika [10]

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).

Tcecarenko [31]

Total distance traveled = 4 + 6 = 10 miles

Total time = 15 + 25 = 40 minutes

Speed = 10 miles ÷ 40 minutes = 0.25 mph
