The seats at a football stadium are on a slope with gradient of 1/2. What is the height of the bottom seats?
2 answers:
Answer:
Height of the bottom seats is 2 meter.
Step-by-step explanation:
It has been given in the question seats are located on a slope having gradient
We have to find the height h of the bottom seats.
Since gradient =
Therefore, from the figure attached,
12 - h =
12 - h = 10
h = 12 - 10
h = 2 m
Therefore, height of the bottom seats if 2 m.

Answer:
(a) The probability of the event (<em>X</em> > 84) is 0.007.
(b) The probability of the event (<em>X</em> < 64) is 0.483.
Step-by-step explanation:
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 64.
The probability mass function of a Poisson distribution is:
(a)
Compute the probability of the event (<em>X</em> > 84) as follows:
P (X > 84) = 1 - P (X ≤ 84)
Thus, the probability of the event (<em>X</em> > 84) is 0.007.
(b)
Compute the probability of the event (<em>X</em> < 64) as follows:
P (X < 64) = P (X = 0) + P (X = 1) + P (X = 2) + ... + P (X = 63)
Thus, the probability of the event (<em>X</em> < 64) is 0.483.
