Describe the difference between plots that show a strong correlation and plots that show a weak correlation.

Answers

Answer 1

We need to find the difference between plots that show a strong correlation and plots that show a weak correlation.

The point of creating a scatter plot is to determine if there is a correlation. Correlation means the relationship between two quantities. For example, there is a correlation between how much a person studies and the grade they get on a test, but there is no correlation between how much money a person earns and what pets they own. In mathematics, correlation between data means that the points follow a pattern and go in the same direction. There are two types of correlation:

Positive: the trend is rising from left to right

Negative: the trend is decreasing from left to right

If the dots on the scatter plot do not follow a pattern, there is no correlation.

All correlations have two properties: strength and direction. The strength of the correlation is determined by its numerical value. The direction of the correlation is determined by whether the correlation is positive or negative.

The strength of the correlation indicates how strong the relationship is between the two variables. The strength is determined by the numerical value of the correlation. A correlation of 1, whether +1 or -1, is a perfect correlation. In perfect correlations, the data points lie directly on the fit line. The further the data is from the fit line, the weaker the correlation. A correlation of 0 means there is no correlation

If the value of correlation coefficient is nearer to to 1 or -1 , then there exist a strong correlation.

If the value of correlation coefficient is nearer to to 0 , then there exist a weak correlation.

Answer 2

The data points are a little closer for a weak correlation, and you can see that there is some sort of relationship between these factors.

Data points for a strong correlation are in close proximity to one another, making it possible to build a line by imitating their pattern.

A statistic called correlation gauges how much two variables change in connection to one another.

Correlation and diversification, the idea that certain types of risk can be reduced by investing in assets that are not connected, are closely related concepts.

Correlation cannot determine whether x causes y or vice versa, or whether a third component is responsible for the association.

A scatter plot may make it easier to spot correlation, particularly when the variables have a non-linear but nevertheless significant association.

How many short sleeve t-shirts were sold?

Answers

No it’s not like him I’m not it would have Ben 3.4 shirts left

Answer:

The track team sold 31 short sleeved t-shirts.

Step-by-step explanation:

If there were 40 t-shirts sold, then you'd have to find how many short sleeved and long sleeved t-shirts were sold to get the amount of money made. Basically, all I did was start with 20:20. I multiplied the cost of each type of shirt by 20, however, the money from selling long sleeved t-shirts is a lot more than the actually amount. So then, I went to 30:10 with short sleeved and then long sleeved. The amount (when added together) was pretty close to the actual amount but it was still a tiny bit higher than the actual. So, I did 31:9 and the amount came out right.

Find the missing angle measurement in the triangle.

Answers

Answer:

the answer is C

Step-by-step explanation:

the right angle is = 90

the other angle= 55

so you add them together which makes 145

so subtract 180 which is = to a triangle subtract 180-145=35

Answer: C.)

Step-by-step explanation:

Triangle angles add up to 180 degrees.

The box is a right angle which equals 90 degrees.

55 degrees + 90 degrees = 145 degrees, but we need the sum to be 180, so we subtract 145 from 180 and you should get the answer of "35".

An isosceles triangle has two congruent angles. Write an expression to represent the measure of the third angle of the triangle. Explain.

Answers

Step-by-step explanation:

Let x be the size of 1 of the 2 congruent angles.

The size of the other congruent angle is also x.

Since sum of angles in a triangle = 180°,

Measure of 3rd angle in the triangle

= 180° - 1st angle - 2nd angle

= (180 - 2x)°.

Answer:

The Isosceles Triangle Theorem, All interior angles of a triangle add up to 180 degrees. Basically the equation would be (angle 1) + (angle 2) + (angle 3) = 180. whichever angle you dont have you replace with x and solve for it. For example if you had a triangle with two congruent angles of 36 then it would be 36+36+x=180 and you would solve it like any other equation eventually showing you that x = 108. it also works backwards if you are trying to solve for the 2 missing congruent angles.
