Rocco mowed 1 lawn a week.
You wanna divide Carley’s total mowed lawns by the amount of weeks she mowed for.
18/6 = 3
Carley mowed 3 lawns a week.
We’ll take away two from that because she mowed two more that Rocco each week, resulting in Rocco mowing one lawn a week.
Hope this helps!! :))
Finding the correlation coefficient, it is found that the regression line shows a:
negative trend line with a strong relationship.
<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.
Inserting the values of a table, the x-values as 25, 28, 30, 31, 33, 40, and the y-values as 7.5, 6, 5.5, 5, 4.5, 4.5, the coefficient is of -0.85, which is negative and strong.
