Answer:

x=6

Step-by-step explanation:

Given: 4(x+4)+2x=52

Distribute.

4x + 16 + 2x = 52.

Simplify.

6x + 16 = 52.

Subtract 16 on both sides to isolate out the variable.

6x = 36

Divide.

x = 6

Answer:

x = 6

Step-by-step explanation:

first we distribute the 4 to the (x + 4) by multiplying 4 times each of those

4x + 16 + 2x = 52

Then, combine like terms:

6x + 16 = 52

then subtract 16 from both sides of your equation

6x = 36

then divide both sides by 6

x = 6

The probability that a rental car will be stolen is. 4. if 3500 cars are rented, what is the approximate poisson probability tha
kozerog [31]

Using the Poisson distribution, there is a 0.8335 = 83.35% probability that 2 or fewer will be stolen.

<h3>What is the Poisson distribution?</h3>

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}

The parameters are:

  • x is the number of successes
  • e = 2.71828 is the Euler number
  • \mu is the mean in the given interval.

The probability that a rental car will be stolen is 0.0004, hence, for 3500 cars, the mean is:

\mu = 3500 \times 0.0004 = 1.4

The probability that 2 or fewer cars will be stolen is:

P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)

In which:

P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}

P(X = 0) = \frac{e^{-1.4}1.4^{0}}{(0)!} = 0.2466

P(X = 1) = \frac{e^{-1.4}1.4^{1}}{(1)!} = 0.3452

P(X = 2) = \frac{e^{-1.4}1.4^{2}}{(2)!} = 0.2417

Then:

P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.2466 + 0.3452 + 0.2417 = 0.8335

0.8335 = 83.35% probability that 2 or fewer will be stolen.

Part C Now try this one. Write a description of the partitioned function using known function types, including transformations.
Sever21 [200]

Answer:

Following are the function description to the given question:

Step-by-step explanation:

In the given-question, three functions are used, that can be defined as follows:  

In function 1:

This function is also known as the modulus on the absolute value function, for example:

f(x)=| x| \left \{ {{x , \ \ \ x>0} \atop {-x, \ \ \ \x

In the given in the above graph, that is f(x) = -x , \ \  x

In function 2:

In this function, It is an algebraic function that is y=x^2

It is also a part of the quadratic polynomial function, and its value is y=x^2 , \ \ \ x> 0  

In function 3:

In this function, it is the cubic polynomial equation that's value is y=x^3

In the graph its value is:

y=-x^3\\\\and \\ \\\to y= f(x) \\\\ \to y=-f(x)\\
