A linear correlation coefficient is a number calculated from given data that measures the strength of the linear relationship between two variables: x and y. The sign of the linear correlation coefficient indicates the direction of the linear relationship between x and y.
Compute the standardized value of each yi using the formula (zy)i = (yi – ş) / s y . Assemble the product from the last step. Divide the previous step sum by n - 1. where n is the total number of points in the paired data set. All these results have a correlation coefficient of r
. The correlation coefficient formula indicates how close the linear relationship is between two variables. R-squared is the square of the correlation coefficient r (hence the formula r-squared).

Answer:
Step-by-step explanation:
p+n+d+q=50
p=.16(50)=8
n=p+6=8+6=14
d=.32(50)=16
q=50-p-n-d=50-8-14-16=12
A=8(1)+14(5)+16(10)+12(25)
A.=8+70+160+300
A=538 cents
A=$5.38
Answer:
16
Step-by-step explanation:
Age problems can be solved by expressing the given relationships in math terms, then solving the resulting equation(s). Let J represent Judy's age now. Then Adami's age now is J/2. Six years ago, the relationship was ...
(J -6) = 5(J/2 -6)
J -6 = 2.5J -30
24 = 1.5J
16 = J
Judy is now 16 years old.

<em>Additional comment</em>
Adami is 8 now. 6 years ago, Judy was 10 and Adami was 2.
Here is an alternate approach. Let 'a' represent Adami's age 6 years ago. The relationship at present is ...
2(a+6) = 5a +6
6 = 3a . . . . . . . . . simplify, subtract 2a+6
2 = a ⇒ 5a+6 = 16
A please? Jk but 3/20 and 3/10 and 9/20 have a pattern just make 3/10 6/20 by doubling it. She added 3/20 every time she ran again
Just keep going till you hit a hole fraction. By the 7th time she ran she ran 1 1/20 mile
Answer:
x=2
