Answer:24 pi square units
Step-by-step explanation:
Answer is From all those aforementioned, the true statement is: Thanh’s grade is 2.5 standard deviations below the mean of the test grades.
explanation
The z scores are standard deviations. If, for example, a tool returns a z score of +2.5, it means that the result is a standard deviation of 2.5. Very high or very low (negative) z scores associated
with very low p values are at the ends of the normal distribution.
V-6>=4
+6 +6
v>=10
add 6 on both sides to simplify this inequality.
The polynomial 9x^5+36x^4+189x^3 in factored form is 
<u>Solution:</u>
Given, polynomial equation is 
We have to find the factored form of the above given polynomial equation.
Let us solve it by grouping.
Now, take the polynomial ⇒ 
By taking common term out, we get


Grouping the terms we get,

Taking common terms out from each group,



Thus the factored form of polynomial is found out
