Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk
10 / 1 is a rational and which is equal to 10 so 10 is also a rational number

Answer:
28.65% probability that the next customer will not arrive for 5 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:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
Mean of 15 customers an hour:
An hour has 60 minutes, so in the space of 5 minutes, the mean is:
A customer walks in what is the probability that the next customer will not arrive for 5 minutes?
This is P(X = 0).
28.65% probability that the next customer will not arrive for 5 minutes
