Find the z score that corresponds to P99, the 99th percentile of a standard normal distribution curve.

Answer:
D. <em>2.33</em>
Step-by-step explanation:
Hint- We have to use Inverse Normal Probability Distribution function. This function returns the x-value given the probability region to the left of the x-value.
We have to calculate the z score of the 99th percentile of a standard normal distribution curve.
i.e the value of probability less than z is given as 99th percentile or 0.99
Using inverse normal probability distribution function, we get

Answer:
y = - x -
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 5x + 9y + 18 = 0 into slope- intercept form
Subtract 5x + 18 from both sides
9y = - 5x - 18 ( divide all terms by 9 )
y = - x - 2 ← in slope- intercept form
with m = -
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation
To find c substitute (- 5, - 7) into the partial equation
- 7 = + c ⇒ c = - 7 -
= -
y = - x -
← equation of line
