It should we around 37
Step-by-step explanation:
Answer:
(c) Near 0.
Since there is no connection or relationship between the shoe size of classmates and marks score by them therefore,there is no interdependency or correlation between these two variables. Therefore, coefficient of correlation between them will be near to 0. Therefore option (c) is the correct answer.
Step-by-step explanation:
Correlation coefficient is a statistical tool that exhibits the the dependency and relationship between two variables. In other words, correlation coefficient measures how one variable is related to another variable.
Coefficient of correlation ranges between +1 to -1. If correlation is positive 1 it shows the two variables are perfectly correlated to each other. If correlation is -1 it shows the variables are negatively related to each other which mean rise in one leads to fall in other. zero correlation means there is the variables are not related to each other in any terms.
For example, If high rainfall causes rise in a production of crops. It shows that there is positive correlation between the rainfall and crop production.
Assuming we are being asked the subtended angle of the arc,
S = r∅; where ∅ is the angle.
7 = 12∅
∅ = 7/12 radians
I don't think that is possible. 9+ (-5)=4 but it multiplies to -45 and -5 -(-9)=4 but you would need to subtract them instead of adding them.
