Answer:

0.1535 = 15.35% probability that at least one customer arrives in a particular one minute period.

0.1443 = 14.43% probability that at least two customers arrive in a particular 4 minute period.

Step-by-step explanation:

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

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

Find the probability that at least one customer arrives in a particular one minute period.

The average is of 10 customers per hour(60 minutes), so for this case, [tex]\mu = \frac{10}{60} = \frac{1}{6}[/tex]

This is:

[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]

In which

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-\frac{1}{6}}*(\frac{1}{6})^{0}}{(0)!} = 0.8465[/tex]

[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.8465 = 0.1535[/tex]

0.1535 = 15.35% probability that at least one customer arrives in a particular one minute period.

Probability that at least two customers arrive in a particular 4 minute period.

The average is of 10 customers per hour(60 minutes), so for this case, [tex]\mu = \frac{10*4}{60} = \frac{4}{6} = \frac{2}{3}[/tex]

This probability is:

[tex]P(X \geq 2) = 1 - P(X < 2)[/tex]

In which

[tex]P(X < 2) = P(X = 0) + P(X = 1)[/tex]

So

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-\frac{2}{3}}*(\frac{2}{3})^{0}}{(0)!} = 0.5134[/tex]

[tex]P(X = 1) = \frac{e^{-\frac{2}{3}}*(\frac{2}{3})^{1}}{(1)!} = 0.3423[/tex]

[tex]P(X < 2) = P(X = 0) + P(X = 1) = 0.5134 + 0.3423 = 0.8557[/tex]

[tex]P(X \geq 2) = 1 - P(X < 2) = 1 - 0.8557 = 0.1443[/tex]

0.1443 = 14.43% probability that at least two customers arrive in a particular 4 minute period.

Complete question is missing, so i have attached it.

Answer:

Yes, they are all correct

Step-by-step explanation:

From the attached image, we see that the sign is showing;

Parking lot: ¾ miles

Summit: 1½ miles

Summit distance can also be expressed as an improper fraction = 3/2 miles

Now, since they started hiking from the park to the summit, it means that they had moved ¾ mile from the parking lot and had 3/2 miles left to get to the summit.

Thus, total distance from parking lot to summit = ¾ + 3/2 = 9/4 miles

Now, let's analyze each of their statements;

Mai said they are a third of their way there.

They had covered 3/4 mile and the total distance is 9/4 miles.

Thus, fraction of total distance covered is;

9/4 ÷ 3/4 = 1/3.

So, Mai is correct

Clare said they have to go twice as far as they had already gone.

They had covered 3/4 miles.

Therefore, twice this = 2 × 3/4 = 6/4 = 3/2 which is same as the sign distance left to the summit.

Thus, Clare is correct

Tyler said that the total hike is three times as long as what we have already gone.

They had gone 3/4 miles

3 times this = 3 × 3/4 = 9/4 miles.

This tallies with the total distance calculated earlier.

Thus, they are all correct

Answer:

First, we should know what the slope-intercept formula is.

Y = MX + B

Where M is your slope, and B is your y intercept.

Let's do the easiest part first, finding our y-intercept. The y-intercept is where the the line intersects the y-axis. In this case, y = 1, because it intersects at (0, 1).

Now we have:

y = mx + 1

Next, we need to calculate the slope, or rise over run. M is presented as a fraction. The numerator is your rise (how high or low it goes), and the denomenator is your run (how far to the right or left it goes).

If it goes LEFT, the number is negative, if it goes RIGHT it is positive.

Also, pretty points are areas in which the line hits an exact coordinate. Using these points is easiest if you want to find the slope of the line.

We can see that the line hits a pretty point every time it goes one coordinate (box) to the right, and up three boxes. What this means it is rises three 3 points, and runs to the right, 1. This is shown as [tex]\frac{3}{1}[/tex]

So let's add that to the equation!

Answer:

Step-by-step explanation:

The turning point (maximum or minimum) of quadratic function ...

  f(x) = ax² +bx +c

is at x = -b/(2a).

Here, this means the maximum profit will be had when the number of widgets produced weekly is ...

  x = -88/(2(-2)) = 22

The profit at that level of production is ...

  P(22) = (-2·22 +88)(22) -384 = 44(22) -384 = 968 -384 = 584 . . . hundreds

22 widgets must be produced weekly for the maximum weekly profit of $58,400.

Answer:

x = 10

Step-by-step explanation:

this is because if we look at the equation and do the opposite of addition (subtraction) we will have an equation that looks like this

16 - 6 = x

with this info we can now infer that 16 - 6 will give us a sum of 10

16 - 6 = 10

x = 10

we can as well as check our answer by plugging in the 10 into our original equation

10 + 6 = 16

which will give us the correct mathematical equation

Answer:

164,340

Step-by-step explanation:

If n=32 and it has no sign next to it then it means you must multiply so 120 x 32 = 3840 and 3840 + 160,500 = 164,340.

Hope this helps and have a wonderful day :)

Answer:

164,340

Step-by-step explanation:

equation:

⇒ 120n + 160,500

n = 32

substitute 32 for n in the equation:

⇒ (120)(32) + 160,500

solve:

⇒ (120)(32) + 160,500

⇒ 3,840 + 160,500

⇒ 164,340
