Answer:
Jessica scored 835 points,
and Tina scored 717 points.
Step-by-step explanation:
Let $j$ stand for Jessica Bradley, and let $t$ stand for Tina Harner. By turning the words of this problem into equations, we get:
j - 118 = t
and, j + t = 1552.
Now that we have a system of equations, all we have to do now is to solve it.
By substituting the value of t (first equation) into the second equation, we get:
j + (j - 118) = 1552.
Get rid of the parentheses:
j + j - 118 = 1552
Simplifing:
2j - 118 = 1552
2j = 1670
j = 835.
Now that we know how many points Jessica scored, we can easily find out how many points Tina scored. By sticking in the value of Jessica's score into the first equation.
835 - 118 = t
t = 717.
So, the answer to this problem is (j, t) = (835, 717).
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.
