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.

Answer:
2/13
Step-by-step explanation:
In a deck of 52 cards, there are 2 sets of red cards. Diamonds and Hearts. In each set of red cards, there are 4 fives. If there are 2 sets, that means that there are 8 red fives in the deck of 52 cards. This means that the probability is 8/52 which is simplified into 2/13.
Download the app Math then take a picture and it wil give u the answer.
A^2+b^2= c^2
Plug in the points. the longest side is always c.
95.2^2+ b^2= 168^2.
Square the numbers.
9063.04+ b^2= 28224
Subtract 9063.04 on both sides.
b^2= 19160.96
Find the square root.
b= 138.423119456
Or, b= 138.4 (rounded down)
I hope this helps!

Step-by-step explanation:
slope formula' ]is (y2 - x2)/(y1-x1)
answer is 3-(-3) / -12-(-8)
=6/-4
=-1 1/2
sorry for the weird sign i amm typing with a fractered arm
