Answer:
It will cost $9.80
Step-by-step explanation:
To find the cost, you have to divide the cost for 7 prints and then multiply it by 49.
1.40÷7= 0.2
0.2×49= 9.8
The answer that you get is the total cost for 49 prints.
62.8cm^2 I think that's the answer
Answer:
a) P=0.535
b) P=0.204
c) P=0.286
Step-by-step explanation:
The exponential distribution is expressed as

In this example, λ=1/8=0.125 min⁻¹.
a) The probability of having to wait more than 5 minutes

b) The probability of having to wait between 10 and 20 minutes

c) The exponential distribution is memory-less, so it is independent of past events.
If you have waited 5 minutes, the probability of waiting more than 15 minutes in total is the same as the probability of waiting 15-5=10 minutes.
