The qualities of the set {(x,y): x>0,y>0} is as under:
- All points lie in first quadrant.
- All values are positive and greater than zero.
Given a set {(x,y),x>0,y>0}.
We are required to determine the qualities of the set.
We know that a set is a collection of things,numbers, fractions, etc.
In any set the values of x represents the domain of the function and the values of y represents the value of codomain of the function with which the set belongs to.
Set={(x,y): x>0,y>0}
From the above set we can find the qualities stated below:
- All points lie in first quadrant as the first quadrant only contains positive values of x and y.
- All values are positive because it is given that they are greater than zero
Hence the qualities of the set {(x,y): x>0,y>0} are that all values should be in first quadrant and all the values are positive.

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:
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).
There are 90 teenage girls in the concert hall.
2/5 x 600 = 240
3/8 x 240 = 90
Answer:
32 inches: 90 feet
Step-by-step explanation:
The question is asking for a ratio of inches to feet. Since you want the scale to be an integer, we find the lowest number to multiply 6.4 inches by to get an integer. Since 6.4 inches = 32/5, multiply by 5, leaving 32 inches. However, since you multiplied 6.4 by 5, you have to multiply 18 by 5. 6.4*5 inches: 18*5 feet, or 32 inches: 90 feet.
Her team scored a total of 22+39 = 61 points. This is 8 points higher than the other team, so the other team scored 61-8 = 53 points.
