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%.

Answer:
(x+5) and (x-7).
Step-by-step explanation:
The given equation is :

We need to write it in factored form.
We know that,
7×5 = 35 and 7-5 = 2
So,

Hence, the required factors are (x+5) and (x-7).
Answer:
All pencils down, turn in your tests, put them in a stack on my desk" ordered the professor to the class of 200 students.
Almost every student put their pencil down except for one student who was adding to their last answer. When the other students had handed in their tests the late student walked up to the professor's desk.
"You failed" exclaimed the teacher. "You didn't put down your pencil in time and you have failed this test."
Suddenly the late student became indignant. "Do you know who I am?! DO YOU KNOW WHO I AM?!"
"Frankly, I do not nor do I care" the professor countered.
So the late student stuck his test into the middle of the stack of papers and walked out of the room.
