1/4 x 3 = 3/4 = 6/8

3/8 x 4 = 12/8

1/2 x 3 = 3/2 = 12/8

5/8 x 2 = 10/8

6/8 + 12/8 + 12/8 + 10/8 = 40/8 = 5 lbs

Find the area of the trapezoid<br> 3cm, 3cm, 8cm

love history [14]

The area of the trapezoid is the amount of space on it, and the value of the area is 16.5 square cm

<h3>How to determine the area?</h3>

The given parameters are:

Parallel sides = 3cm and 8 cm

Height = 3cm

The area is then calculated using:

Area = 0.5 * (Sum of parallel sides) * Height

So, we have:

Area = 0.5 * (3 + 8) * 3

Evaluate

Area = 16.5

Hence, the area of the trapezoid is 16.5 square cm

Assume that the number of customers who arrive at a water ice stand follows the Poisson distribution with an average rate of 6.4

Nady [450]

Answer:

18.88% probability that three or four customers will arrive during the next 30 minutes

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:

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

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given time interval.

Average rate of 6.4 per 30 minutes.

This means that $\mu = 6.4$

What is the probability that three or four customers will arrive during the next 30 minutes?

$P = P(X = 3) + P(X = 4)$

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

$P(X = 3) = \frac{e^{-6.4}*(6.4)^{3}}{(3)!} = 0.0726$

$P(X = 4) = \frac{e^{-6.4}*(6.4)^{4}}{(4)!} = 0.1162$

$P = P(X = 3) + P(X = 4) = 0.0726 + 0.1162 = 0.1888$

18.88% probability that three or four customers will arrive during the next 30 minutes
