Suppose that x is normally distributed with mean 110 and standard deviation 30.
scoray [572]
Standard the random variable X using the transformation

Z=\dfrac{X-\mu}\sigma

where \mu and \sigma are the mean and standard deviation of X, respectively.

\mathbb P(X\ge170)=\mathbb P\left(\dfrac{X-110}{30}\ge\dfrac{170-110}{30}\right)=\mathbb P(Z\ge2)

Now, you can recall that for any normal distribution, approximately 95% of its data falls within 2 standard deviations of the mean, so to either side, there is approximately 2.5% of data that falls below 2 standard deviations from the mean, and 2.5% that falls 2\sigma above \mu. In other words, \mathbb P(Z\ge2)\approx0.025.

Find the midpoint of R(2,2) and S(-3,6)
musickatia [10]

Answer: (-0.5, 4)

Step-by-step explanation:

Midpoint formula: (\frac{x1+x2}{2} ,\frac{y1+y2}{2} )

(x1, x2)=(2, -3)

(y1, y2)=(2, 6)

-----------------------------------------------

 (\frac{x1+x2}{2} ,\frac{y1+y2}{2} )

=(\frac{2-3}{2} ,\frac{2+6}{2} )

=(\frac{-1}{2} ,\frac{8}{2} )

=(-0.5, 4)

Hope this helps!! :)
