HELPPPPPPPPPP!!!!!!! Calculate the correlation coefficient for the following data, showing all work. What does it tell you about
stiks02 [169]

Answer:

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

r=\frac{SSxy}{\sqrt{(SSxx)(SSyy)}}

To find SSxy

SSxy= ∑xy- ∑\frac{(x)(y)}{n}

To find SSxx

SSxy= ∑x^{2}- (∑x)^{2}/n

To find SSyy

SSxy= ∑y^{2}- (∑y)^{2}/n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.

Show that KLPQ is a parallelogram
Alex787 [66]

Step-by-step explanation:

m = 14, n = 12.5

m<L = (5m + 36)° = (5(14) + 36)°

L = 106°

m<p= (6n-1°)=(6x12.5-1°)

p=74°

m<Q = (4m + 50)° = (4(14) + 50)°

Q = 106°

k=360°-(106°+74+°106°)=360°-286°

k=74°

The sum of the interior angle of a parallelogram is 360°

The opposite side of a parallelogram are equal.
