Following are simplifications to the given expression:

Given:

$\bold{(3x-1)(x-3)}$

To find:

simplify=?

Solution:

$\to \bold{(3x-1)(x-3)}\\\\\to \bold{(3x^2-9x-x+3)}\\\\\to \bold{(3x^2-10x+3)}\\\\$

Therefore, the final answer is " $\bold{3x^2-10+3}$ ".

Step-by-step explanation:

A.) Ok, so the mean price for Southtown is 72,800.

And the mean price for middle town is 54,900

So Southtown has the higher mean price.

Explanation:

To find the mean. You must first add up all the numbers, then divide the total by how many numbers you added up.

72,000 + 50,000 + 68,000 + 93,000 + 81,000 = 364,000

Then,

364,000/ 5 = 72,800

B.) It is 17,900

Explanation:

72,800 - 54,900 = 17,900

Hope this helps you out!!! : )

The waiting time at an elevator is uniformly distributed between 30 and 200 seconds. what is the probability a rider must wait m

stira [4]

1.5 minutes = 90 second

The probability density function is

$f_X(x)=\begin{cases}\dfrac1{200-30}=\dfrac1{170}&\text{for }30\le x\le200\\\\0&\text{otherwise}\end{cases}$

so the probability of interest is

$\mathbb P(X>90)=\displaystyle\int_{90}^\infty f_X(x)\,\mathrm dx$
$\mathbb P(X>90)=\dfrac1{170}\displaystyle\int_{90}^{200}\mathrm dx$
$\mathbb P(X>90)=\dfrac{200-90}{170}=\dfrac{11}{17}\approx0.6471$

Answer: The polynomial 3x2 is of one variable with a degree of 2.

The polynomial x2y + 3xy2 + 1 is of two variables a with a degree of 3.

Step-by-step explanation: For this case we have the following polynomials:

3x2

x2y + 3xy2 + 1

We have then:

For 3x2:

Classification: polynomial of one variable:

Degree: 2

For x2y + 3xy2 + 1:

Classification: polynomial of two variables

Degree: 2 + 1 = 3
