Answer:
(a) The probability of having exactly four arrivals during a particular hour is 0.1754.
(b) The probability that at least 3 people arriving during a particular hour is 0.7350.
(c) The expected arrivals in a 45 minute period (0.75 hours) is 3.75 arrivals.
Step-by-step explanation:
(a) If the arrivals can be modeled by a Poisson process, with λ = 5/hr, the probability of having exactly four arrivals during a particular hour is:

The probability of having exactly four arrivals during a particular hour is 0.1754.
(b) The probability that at least 3 people arriving during a particular hour can be written as

Using

We get

The probability that at least 3 people arriving during a particular hour is 0.7350.
(c) The expected arrivals in a 45 minute period (0.75 hours) is

Answer:
x = -2
Step-by-step explanation:
Equation is given as;
4 x - 5 = 2 + 3 ( x - 3 )
Step 1: Expand the brackets
4x - 5 = 2 + 3x - 9
Step 2: Collect like terms
4x - 3x = 2 - 9 - (-5)
Step 3: Simplify
x = 2 - 9 + 5
x = -2
Answer:
Step-by-step explanation:
Line 1
y= 3/2x +7/2 m = 3/2
Line 2
4x-6y+2 = 0 m = 2/3
Line 3
y = 3/2x - 4 m = 3/2
Line 1 and Line 2 = neither
Line 1 and Line 3 = parallel
Line 2 and Line 3 = neither
Answer:
2p + 13
Step-by-step explanation:
You need to multiply the numbers in the parentheses first then you can simplify.
Can I have BRAINLIEST please?
Hope this helps!
Please help me with the last question just write the equation in vertex form
I’ll mark as brainliest
