Writing the domain in words: negative infinity to three halves and three halves to infinity
So, Option A is correct.
Step-by-step explanation:
We need to find domain of the function: 
<u>Domain:</u>
The domain of function is defined as all the input values for which the function is defined.
In other words we can say that any value of x that makes the denominator zero is not considered as domain of function.
In the function given:
if x= 3/2 then the denominator will be zero and the function will not be defined.
So, value of x should be x>3/2 or x<3/2
We can write domain as: (-∞,3/2)(3/2,∞)
3/2 can be written as three halves.
Writing the domain in words: negative infinity to three halves and three halves to infinity
So, Option A is correct.

Answer:
Probability that exactly 15 buyers out of 20 will prefer red is 0.0148.
Step-by-step explanation:
This problem has binomial probability distribution.
So probability of success ( population preferring Red colour) i.e. p = 50% = 0.5
therefore probability of failure ( population preferring other colors ) i.e. q = 1 - p = 1 - 0.5 = 0.5
20 buyers are selected at random, therefore n = 20.
We need to find the probability that exactly 15 buyers would prefer red and so r = 15 and it is given by,
P( X = r ) = 
So, P ( X = 15 ) = 
= 
= 
Answer: The second matrix
If we want to write a proper matrix to represent the given system of equations, we have to arrange it in order:
After this, we can write the matrix with the coefficients of each equation:
![\left[\begin{array}{ccc|c}1&1&1&180\\2&-1&0&0\\4&0&-1&-5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Cc%7D1%261%261%26180%5C%5C2%26-1%260%260%5C%5C4%260%26-1%26-5%5Cend%7Barray%7D%5Cright%5D)
