Answer:
97.6% of the trees will have diameters between 7.6 and 18.6 inches.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12 inches
Standard Deviation, σ = 2.2 inches
We are given that the distribution of diameter of tree is a mound shaped distribution that is a normal distribution.
Formula:
P(diameters between 7.6 and 18.6 inches)
97.6% of the trees will have diameters between 7.6 and 18.6 inches.

Answer:
59 = (5x + 4)
x = 11
Step-by-step explanation:
59 = (5x + 4)
5x + 4 = 59
5x = 59 - 4
5x = 55
x = 55/5
x = 11
The probability of one arrives within the next 10 minutes
when he already been waiting for one jour for a taxi is,
P (X > 70 | X > 60) = P (X > 10) = 1 – P (X ≤ 10)
= 1 – {1 – e ^ -((1 / 10) 10)} = e ^ -1
= 0.3679
The probability of one arrives within the next 10 minutes
when he already been waiting for one hour for a taxi is 0.3679
