The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the proba
Olegator [25]

Answer:

The probability that occurrence of 8 in ten minutes is 0.0771.

Step-by-step explanation:

Poisson Distribution:

A discrete random variable X having the enumerable set {0,1,2,.....} as the spectrum, is said to have Poisson distribution with parameter \mu (>0), if the p.m.f is given by

P(X=x)=\frac{e^{-mu}\mu^x}{x!}  for x=0,1,2,...

               = 0,           elsewhere

The mean number of occurrences in ten minutes is 5.3.

Here \mu = 5.3 and x= 8

P(X=8)=\frac{e^{-5.3}(5.3)^8}{8!}

               =0.0771

The probability that occurrence of 8 in ten minutes is 0.0771.

Given triangle, ABC is congruent to triangle EDC find A
arlik [135]

Answer:

m<A = 30 degrees.

Step-by-step explanation:

m < C in triangle ABC = m < C in EDC so

x + 13 + 42 + x + 13 = 180

2x = 180 - 13 - 13 - 42

2x = 112

x = 56.

So m < C = 56+13 = 69.

m < B = m < D = 81

M < A = 180 - 69 - 81

= 180 - 150 = 30.

Given the quantities a = 8.9 m, b = 4.9 s, c = 71 m/s, what is the value of the quantity d = a3/(cb2)
11Alexandr11 [23.1K]

The given expression is

d = \frac{a^3}{c b^2}

We have to find the value of d , given the values of a,b and c are 8.9m,4.9 s , 71m/s respectively .

To find the value of d, we have to substitute the given values of a,b and c, that is

d = \frac{8.9^3}{71*4.9^2}

d = 0.4135
