Using the normal distribution, it is found that 63.18% of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The area within 0.9 standard deviations of the mean is the <u>p-value of Z = 0.9(0.8159) subtracted by the p-value of Z = -0.9(0.1841)</u>, hence:
0.8159 - 0.1841 = 0.6318 = 63.18%.

To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3
<em>Answer:</em>
<em>200 points Vanessa</em>
<em>Step-by-step explanation:</em>
<em>M = 165%V</em>
<em>330 = 165V/100</em>
<em>33000 = 165V</em>
<em>V = 33000 : 165</em>
<em>V = 200 points Vanessa</em>
Answer: domain (-2, 3] range [-2, 2)
These are the x-values left to right the paretheses ( ) indicates "not equal to" a bracket [ ]
Step-by-step explanation: Domains are the x-values left to right the parentheses ( ) indicates "not equal to" like the open circle on the graph; a bracket [ ] means "and equal to" like the solid circke on the graphed line.
Range means the y-values, bottom to top (least to greatest in math lingo)
