The auto parts department of an automotive dealership sends out a mean of 4.34.3 special orders daily. What is the probability t

Svetlanka [38]

Answer:

$P(X = 5) = 0.166$

Step-by-step explanation:

Given

$Mean = 4.3$

$x = 5$

Required

Determine the probability that the order is 5

This question can be answered using Poisson distribution.

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

Where

$\alpha$ is used to represent the mean

and

$\alpha = 4.3$

$x = 5$

$e = 2.71828$ ---- Euler's constant

So, we have:

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

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5!}$

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{5* 4 * 3 * 2 *1}$

$P(X = 5) = \frac{4.3^5 * 2.71828^{-4.3}}{120}$

$P(X = 5) = \frac{1470.08443 * 0.01356859825}{120}$

$P(X = 5) = \frac{19.9469850243}{120}$

$P(X = 5) = 0.1662248752$

$P(X = 5) = 0.166$ Approximated

Can someone fr help me with this like right now i’ll appreciate it sm

rjkz [21]

Step-by-step explanation:

Since

$\frac{108}{72} = \frac{3}{2}$

$\frac{72}{48} = \frac{3}{2}$

$\frac{48}{32} = \frac{3}{2}$

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

$y = a(b) {}^{x}$

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

$y = 32 ( \frac{3}{2} ) {}^{x}$

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.

4(x+6)≤−56 it says Solve the inequality.

vlabodo [156]

$\tt \: 4(x + 6) \leqslant - 56$

Divide both sides of the inequality by 4

$\sf \: x + 6 \leqslant - 14$

Move the constant to the right-hand side and change its sign

$\bf \: x \leqslant - 14 - 6$

Calculate the difference

$\rm \: x \leqslant - 20$

And we are done solving!!~

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?

Black_prince [1.1K]

Write out the governing equation:

y = kx.

Take any point from the given table. You haven't shared the table, so I will invent a point: (2, 9).

Then find k: k = 9/2 Then the equation becomes y = (9/2)x.

Now let x = 7 and find y: y = (9/2)(7) = 63/2

Answer: y = 63/2
