Paraphin [41]

Answer:$10 each

Step-by-step explanation: We can denote the amount each player pays by x. Since the amounts are equal, and there are 5 soccer players, the total is 5x. We are told that the total is 50, so 5x=50. Hence, x = $10. So each soccer player pays $10 each.

Nutka1998 [239]

Answer:

204 4/9 °C

Step-by-step explanation:

Put the number in the formula and do the arithmetic.

°C = (5/9)(400 -32) = 5/9(368) = 204 4/9

The temperature in °C is 204 4/9.

_____

Most likely, it would be written as 205 °C in a metric version of the recipe.

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 $\mu = 6$ .
