Professor Gym conducts a study in which he determines that there is a correlation of​ +1.32 with 15 degrees of freedom between the speed of a dodge ball and the welt inflicted on the arm of the dodge ballers. He has now come to you for help with interpreting his results. What can you tell​ him?

Formula

r =\frac{\sum\left(x_{i}-\bar{x}\right)\left(y_{i}-\bar{y}\right)}{\sqrt{\sum\left(x_{i}-\bar{x}\right)^{2} \sum\left(y_{i}-\bar{y}\right)^{2}}}

r=correlation coefficient

x_{i}=values of the x-variable in a sample

\bar{x}=mean of the values of the x-variable

y_{i}=values of the y-variable in a sample

\bar{y}=mean of the values of the y-variable

now try btw use a calcutator

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
