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.

Anna purchased a house for $416,000 and obtained a mortgage for $394,000. She purchased 4 discount points and 5 origination poin
mrs_skeptik [129]
Cost of discount/origination points = 1% of the mortgage*number of  pints in question.

In the current scenario:
Mortgage taken = $394,000
Discount points = 4
Origination points = 5

Then,
Cost of discount points = 0.01*394,000*4 = $15,760
Cost of origination points = 0.01*394,000*5 = $19,700
