Find the distance (8,-7) (-4,-2)

Vinil7 [7]

Distance = 13 units

Point A: (8, -7)

Point B: (-4, -2)

$\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }$

$\sqrt{(12)^{2} + (-5)^{2} }$

$\sqrt{144 + 25 }$

$\sqrt{169}$

Answer:

111°

Step-by-step explanation:

Let the centre of the circle be C

mRQ=157 (marked)

The angle at the centre of a circle standing on an arc is twice any angle at the circumference, standing on the same arc. So <SCR=2(SQR)=2(46)=92. mSR=<SCR=92

All the arc measure add up to 360 so:

mSQ+mRQ+mSR=360

mSQ+157+92=360

mSQ=360-249=111

Answer:

The Pearson's coefficient of correlation between the is 0.700.

Step-by-step explanation:

The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent).It ranges from -1 to +1.

The formula to compute correlation between two variables <em>X</em> and <em>Y</em> is:

$r(X, Y)=\frac{Cov(X, Y)}{\sqrt{V(X)\cdot V(Y)}}$
