(a) We need to figure out the deciles for a normal distribution curve in this part.
In order to do so, we need to find the z score corresponding to probability 0.10 and 0.90 on the normal distribution curve.
Upon looking at the normal distribution table, we can see that the probability P = 0.10 corresponds to a z score of -1.28 and probability P = 0.90 corresponds to a z score of 1.28.
Therefore, deciles are -1.28 and 1.28 for a normal distribution curve.
(b) In this part, we are given that mean height is 69.5 inches and standard deviation in height is 2.7 inches. Therefore, we can find the deciles using the z score formula as shown below:

Therefore, the required deciles are 66.044 and 72.956

Things I like about distance learning are:
- I get to sleep in a bit.
- My schedule is more flexible.
- I can work in different environments.

Hope this helps! Good luck on your project! :)
Answer:
A) 5x² - 6x + 1
Step-by-step explanation:
In this question, you would have to simplify the expression.
Solve:
(3x² - 2) + (2x² - 6x + 3)
Combine like terms.
3x² - 2 + 2x² - 6x + 3)
5x² - 2 - 6x + 3
5x² - 6x + 1
Since there's no more like terms, we have completely simplified the expression.
Therefore, your answer would be A) 5x² - 6x + 1
