A cable provider wants to contact customers in a particular telephone exchange to see how satisfied they are with the new digital TV service the company has provided. All numbers are in the 463 exchange, so there are 10 comma 000 possible numbers from 463-0000 to 463-9999. Suppose the numbers are selected with equal probability. Complete parts a through c below.

a) What distribution would they use to model theselection?

b) What is the probability the number selected will be an oddnumber?

c) What is the probability the number selected will end in 555?

a. uniform

b. binomial

c. Poisson

d. geometric

distribution should be used to model the selection.

B) The probability that the number selected will be an odd number is

(Round to three decimal places as needed.)

c) The probability that the number selected will end in 555 is

the aswere is the one with all 8's and the second one is with the 10,8 and 6

step-by-step explanation:

drop out of school or go to quizlet, quizlet is better

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
