Answer:y would equal 2 because when you put a symbol/number next to a number/variable you multiply the two #s/variables and 8x2 would equal 16
Step-by-step explanation:
1-2/3=1/3
1/3^2=1/9
1/9•1/4=1/36
1/36+1/3=13/36
13/36 is your answer
I would say the answer is C as it is the most unbiased, and considers everyone in the residential area, rather than just dog owners or just residents who do not own pets.
The true statement about the graph of the function f(x) = x3 - 2x2 + 4x – 8 is (B) The function has 1 real zero that occurs 1 time.
<h3>How to determine the true statement</h3>
The function of f(x) is represented as:
Differentiate the function f(x)
Calculate the minimum value using:
So, we have:
Substitute 2/3 in f'(x)
The value of f'(2/3) is greater than 0.
This means that the function f(x) has 1 real zero, and it occurs once at point (2,0)
Hence, the true statement is (b)

Answer:
92.12 seconds
Step-by-step explanation:
According to the poisson probability relation :
P(X =x) = (e^-λ * λ^x) / x!
For no calls to be reveived during the period, x = 0
P(X = 0) = (e^-λ * λ^0) / 0!
P(X = 0) = 0.1
0.1 = (e^-λ * λ^0) / 0!
0.1 = e^-λ
Take the In of both sides
In(0.1) = - λ
-2.303 = - λ
λ = 2.303
The length of call in second, l
l = λ / r ; r = arrival rate
r = 90 per hour ; this means ;
90 / 3600 = 0.025
l = 2.303 / 0.025
l = 92.12 seconds
