Answer:
Step-by-step explanation:
2
The coefficient is the number in front of the variable.
So, in this case, the coefficient of n^2 is 6 and of n is 2.
Answer:
0.91517
Step-by-step explanation:
Given that SAT scores (out of 1600) are distributed normally with a mean of 1100 and a standard deviation of 200. Suppose a school council awards a certificate of excellence to all students who score at least 1350 on the SAT, and suppose we pick one of the recognized students at random.
Let A - the event passing in SAT with atleast 1500
B - getting award i.e getting atleast 1350
Required probability = P(B/A)
= P(X>1500)/P(X>1350)
X is N (1100, 200)
Corresponding Z score = 

B) Commutative property of Multiplication
Hope this helps!
We can write the domain and range in interval notation which uses values within brackets to describe a set of numbers in interval notation we use a square bracket [ when the set includes the endpoint and a parenthesis ( to include that the endpoint is either not included or the interval is unbounded for example if a person has $100 to spend he or she would need to express the interval that is more than 0 and less than or equal to 100 and write (0, 100]. We will discuss interval notation in greater detail later
