Solution: We are given that the correlation coefficient between ages and numbers of violations is -0.61.
The ages and numbers of violations related as age increases, violations decrease.
Therefore, the option c. as age increases, violations decrease.
The correlation coefficient measures the strength of linear association between two variables. The value of the correlation lies between -1 to 1. -1 indicates the perfect negative linear relationship between two variables. The negative values of correlation means as the one variable increases, the other variable decreases. The correlation of +1 indicates that there is perfect positive linear relationship between two variables. The positive values of correlation means as the one variable increases, the other variable also increases.
In the above statement the correlation value is negative, therefore indicating as age increases, violations decrease.
Answer:
Step-by-step explanation:
y - y₁ = m ( x - x₁)
y - 5 = - 3 (x - 12)
y - 5 = -3x + 36
3x + y = 36 + 5
3x + y = 41
y = -3x + 41
Isolate the x. note the equal sign, what you do to one side, you do to the other.
Multiply 0.4 to both sides
x/0.4(0.4) = 0.6(0.4)
x = 0.6(0.4)
Simplify
x = 0.24
0.24 is your answer for x
