Which scatter plot has a correlation coefficient closest to r=1

The correct answer is the scatter plot which has a strong positive slope of the curve of best fit.

Step-by-step explanation:

A scatter plot shows a relationship between two variables for a particular individual. It is actually a graph where we draw a curve of best fit which can represent the whole data. A scatter plot having the correlation coefficient closest to r = 1, is said to have a very strong correlation between the variables.

A scatter plot would have a strong correlation if the data points of the individual are very close to the line or curve of best fit.

For r = 1 , the correlation is strong and positive.

where are the choices?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
