Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

m-36

———— • 3 = 0 • 3

**Step-by-step explanation:**

P^T is transpote matrix. So the rows of matrix P you write like columns in P^T.

So we have first row: 2, 5, it will be firsl column

2nd row: 8,1 will be 2nd column.

It is matrix:

**Answer:**

The probability that exactly 12 buyers would prefer green

**=0.00555**

**Step-by-step explanation:**

We are given that

p=50%=50/100=0.50

n=14

We have to find the probability that exactly 12 buyers would prefer green.

q=1-p

q=1-0.50=0.50

Using binomial distribution formula

Hence, the probability that exactly 12 buyers would prefer green

**=0.00555**

**Answer:**

If a new product wants to be tested by a company and decides to show 50 samples of this product to 50 selected customers. The company estimates that the probability that the customer buys the product is 0.67, the objective is to determine approximately how many people expect to buy the product.

Let X the random variable of interest "Number of people that will buy a selected product", on this case we now that:

The expected value is given by this formula:

And the standard deviation for the random variable is given by:

So then they can conclude that for each group of 50 people they expect that about 33-34 peoploe will buy the product with a standard deviation of 3.32.

**Step-by-step explanation:**

**Previous concepts**

A **Bernoulli trial** is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

The **binomial distribution** is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

The probability mass function for the Binomial distribution is given as:

Where (nCx) means combinatory and it's given by this formula:

**Solution to the problem**

If a new product wants to be tested by a company and decides to show 50 samples of this product to 50 selected customers. The company estimates that the probability that the customer buys the product is 0.67, the objective is to determine approximately how many people expect to buy the product.

I find the easiest way to answer such a question (with medium accuracy) is to use a graphing calculator. The graph shown in the attachment gives the answers listed above.

___

*From vertex form*

The graphing calculator also makes it easy to find the vertex of the parabola. If we divide by 3 so the scale factor is 1, then the y-value of the vertex is -13/3 and the vertex form of the equation can be written ...

... y = (x +1)² -13/3

This has x-intercepts easily found.

... 0 = (x +1)² -13/3 . . . . x-intercepts are where y=0

... (x +1)² = 13/3 . . . . . . . add 13/3

... x +1 = ±√(13/3) . . . . . take the square root

... **x = -1 ±√(13/3)** . . . . . subtract 1

... **x ≈ {-3.0816660, 1.0816660}**

_____

*Using the quadratic formula*

This equation has a=3, b=6, c=-10, so we can put these values into the quadratic formula to find the x-interecepts.

... x = (-b±√(b²-4ac))/(2a)

... x = (-6 ±√(6² -4(3)(-10)))/(2(3))

... x = (-6 ±√156)/6 = -1 ±√(13/3) . . . or . . . **-1 ±(√39)/3**

8(x^2y^4)^1/2 I think this is the answer
