If x>2, then x^2-a-6 / x^2-4=
nadezda [96]
We know that x > 2 ( or : x ≠ +/- 2 )
We have to factorize the numerator and the denominator:
x² - x - 6 = x² - 3 x + 2 x - 6 = x ( x - 3 ) + 2 ( x - 3 ) = ( x - 3 ) ( x + 2 )
x ² - 4 = ( x - 2 ) ( x + 2 )
\frac{(x-3)(x+2)}{(x-2)(x+2)}= \frac{x-3}{x-2}

On a standardized exam, the scores are normally distributed with a mean of 145 and a standard deviation of 25. Find the z-score
Kryger [21]

Answer:

z = 2.6

Step-by-step explanation:

<u>Use the formula for z-score</u>

z=\frac{x-\mu}{\sigma}\\ \\z=\frac{210-145}{25}\\ \\z=\frac{65}{25}\\ \\z=2.6

This tells us that this person's score of 210 places them 2.6 standard deviations above the mean
