Calculate the area of the regular pentagon below:

jarptica [38.1K]

Answer: 238.95 in²

because this is a regular pentagon

=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.

we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)

=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)

The cost of performance tickets and beverages for family of four can be modeled using the equation 4x+12=48, where x represents

Radda [10]

First you will have to even out the statement so minus 12 from both sides.

4x=36

Now divide both sides by 4

x=9

The ticket is 9 dollars.

Now you have the answer.

Cars arrive at the Wendy's drive-through at a rate of 1 car every 5 minutes between the hours of 11:00 PM and 1:00 AM. on Saturd

mestny [16]

Answer:

1) $P(X = 8) = 0.1033$

$P(X = 9) = 0.0688$

2) Expected number of 200 restaurants in which exactly 8 customers use the drive-through: 20.66

Expected number of 200 restaurants in which exactly 9 customers use the drive-through: 13.76

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.

Question 1. Use the Poisson distribution to calculate the probability that exactly 8 cars will use the drive-through between 12:00 midnight and 12:30 AM on a Saturday night at Wendy's. Do the same for exactly 9 cars.

Cars arrive at the Wendy's drive-through at a rate of 1 car every 5 minutes between the hours of 11:00 PM and 1:00 AM. on Saturday nights. This means that during 30 minutes, 6 cars expected to arrive. So $\mu = 6$ .
