Using a calculator, the correlation coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
Using a calculator, we insert the points (x,y) to find the coefficient. In this problem, the points are given as follows:
(1, 5), (4, 8), (8, 3), (13, 10), (19, 13)
The coefficient is of 0.7649. Since the correlation is greater than 0.6, there is strong correlation.

the square root of 306 is
17.49
Answer: OPTION B
Step-by-step explanation:
You can find the distance between two points by using the following formula:
Given the points (-2,-6) and (0,5), you can identify that:
Therefore, substituting values, you get that the distance between those points is:
The polynomial –2x^2 – x + 2 is a monomial , binomial or trinomial
with a degree of 1 , 2 3 or 4. Your answer is 2.
Answer:
33 sq cm.
Step-by-step explanation:
Let's calculate each shape serperately,
--------
For the square, the area is 25 since
5 × 5 = 25
-------
For the rectangle, the area is 8:
4 × 2 = 8
-----
Add these together to get 33 sq cm
Have a good day :)
