<u>Excel's Normal Distribution</u>

The normal distribution has two parameters: the mean value $\mu$ and the standard deviation $\sigma$ . Since it's a symmetric function the values at the right side of the center value

The normal distribution is a function which integral cannot be expressed in terms of elemental functions. That is why the cumulative probability is usually found in tables, graphs or any digital media like Excel.

The formula NORM.DIST computes the cumulative values for the left tail or $P( X < X_o)$ for a given mean and standard deviation. The parameters are

$NORM.DIST (X_o,\mu,\sigma,cumulative)$

This last parameter tells the formula we want the cumulative left-tail probability or just the value at Xo. This value must be set to TRUE to compute the probability for a range of values, like in the problem at hand.

Since the formula computes the left-tail of the function, we must take advantage of the symmetry of the distribution if we want to compute right-tail values we just subtract the result from 1.

Thus, the correct formula to calculate the required probability is

D. 1 – NORM.DIST(100, 75, 10, TRUE)

Find the z-score for a value of 16 with a mean of 8 and a variance of 5 g

zimovet [89]

If the variance is 5 then the standard deviation is √5.
If Z is the score then Z=(8-16)/√5=-3.58 approx.

What is the complete Factorization 3x^2-75

lozanna [386]

After a first glance you can see that 3x^2 - 75 is not a difference of squares in the current form, because for one 3 and 75 are not squares.

So we'll have to see if we can factor something out of both of them. The only number it can be is 3, because the only number besides 3 that goes into 3 is 1.

So is there any number that can multiply by 3 to equal 75?

If you said 25 then you are correct. :p

So then our problem would look like this:
3(x^2 - 25)

Now we have a difference of squares!

Remember a difference of squares can be factored like this!

(a^2 - b^2) = (a - b)(a + b)

3(x - 5)(x + 5)
Is our answer!
