In a recent​ year, an author wrote 171 checks. Use the Poisson distribution to find the probability​ that, on a randomly selecte
sveticcg [70]

Answer: 0.3741

Step-by-step explanation:

Poison probability ;

P(x) = [U(^x) e(^-U)] ÷ x!

Where U = mean

Note: e = exponential symbol

Number of checks that year = 171

Number of days in a year = 365

U = 171/365 = 0.468

Average checks per day = 0.4685

Probability that at least one check was written per day is can be calculated by;

P(not 0) = 1 - P(0)

Therefore,

P(x) = [U(^x) e(^-U)] ÷ x!

P(0) = [ 0.4685^0 * e^-0.4685] ÷ 0!

P(0) = [ 1 * 0.6259] ÷ 1

P(0) = 0.6259

Therefore,

P(not 0) = 1 - 0.6259 = 0.3741

Consider the following literal equation.
galina1969 [7]

We can solve this in many ways, let's try this one.

T∧2 = 4 pi∧2 * a∧3 / GM    First we will multiply whole equation with variable( or parameter) M and get

M * T∧2 = 4 pi∧2 * a∧3 / G  After that we will divide whole equation with variable ( or parameter )  T∧2 and get

M = 4 pi∧2 * a∧3 / G * T∧2

This is correct answer

Good luck!!!
