Substitute the value of y given by the second equation into the first.
.. 3x -5(-7) = 17
.. 3x +35 = 17
.. 3x = -18
.. x = -6

The solution is (x, y) = (-6, -7).

If we reject the null hypothesis, h0: ρ = 0 , what can we conclude about the population correlation coefficient?
ehidna [41]
If the null hypothesis, H_0:\:\rho =0 is rejected, then we can conclude that the correlation coefficient is significant. This means that there is enough evidence to conclude that a relationship exists between the two (or more) variables involved in the regression.

Of 10<br> Find the gradient of the line segment between the points (2,-2) and (0,-6).
Veseljchak [2.6K]

Answer:

<h3>The answer is 2</h3>

Step-by-step explanation:

The gradient of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1}  \\

From the question we have

m  =  \frac{ - 6 -  - 2}{0 - 2}  =  \frac{ - 6 + 2}{ - 2}   =   \frac{ - 4}{ - 2}  = 2 \\

We have the final answer as

<h3>2</h3>
