Total area=square1+sqrare2
total area=25
one is 9
25=9+squaer2
minus 9
square2=16square meters
Answer:
(a) 
(b) 
(c) P(X ≤ 1) = 0.6321
(d) P(2 ≤ X ≤ 5) = 0.1286
Step-by-step explanation:
From the given information; Let consider X to be the time between two successive arrivals at the drive-up window of a local bank.
However; If X is regarded as the exponential distribution with λ = 1 which is identical to a standard gamma distribution with ∝ = 1
The objective is to compute the following :
(a) The expected time between two successive arrivals is;



(b) The standard deviation of the time between successive arrivals is;




(c) P(X ≤ 1)
P(X ≤ 1) = 1 - e⁻¹
P(X ≤ 1) = 0.6321
(d) P(2 ≤ X ≤ 5)
P(2 ≤ X ≤ 5) = [1 - e⁻⁵] - [1 - e⁻²]
P(2 ≤ X ≤ 5) = 0.9933 - 0.8647
P(2 ≤ X ≤ 5) = 0.1286

Answer:
y = 5/4 x - 7
Step-by-step explanation:
y - y1 = m(x - x1)
y + 2 = 5/4 (x - 4)
y + 2 = 5/4 x - 5
y = 5/4 x - 7
