Approximately 80,000 marriages took place in the state of New York last year. Estimate the probability that for at least one of
sasho [114]

Answer:

a)0,45119

b)1

Step-by-step explanation:

For part A of the problem we must first find the probability that both people in the couple have the same birthday (April 30)

P=\frac{1}{365} *\frac{1}{365}=\frac{1}{133225} \\

Now the poisson approximation is used

λ=nP=80000*1/133225=0,6

Now, let X be the number of couples that birth April 30

P(X ≥ 1) =

1 − P(X = 0) =

1-\frac{(e^-0.6)*(-0,6)^{0} }{0!}

P(X ≥ 1) = 0,45119

B)  Now want to find the

probability that both partners celebrated their birthday on th, assuming that the year is 52 weeks and therefore 52 thursday

P=52*\frac{1}{365} *\frac{1}{365}=\frac{52}{133225} \\

Now the poisson approximation is used

λ=nP=80000*52/133225=31.225

Now, let X be the number of couples that birth same day

P(X ≥ 1) =

1 − P(X = 0) =

1-\frac{(e^-31.225)*(-31.225)^{0} }{0!}

P(X ≥ 1) = 1

Solve for k<br> 6k-2z=12
Oksana_A [137]
First you would add 2z to both sides

6k = 12 + 2z

second divide 6 from both sides

K = (12 + 2z) / 6

^^ thats your answer :)

Find the general solution to the equation y(5) - 4y(4) + 4y(3) = 1.
tensa zangetsu [6.8K]

Answer:

y= -1/23

Step-by-step explanation:

The equation y(5)-4y(4)+4y(3)=1 can be solved thus:

Work on brackets first:

5y-16y+12y=1

Add up y values

5y-28y=1

Divide both sides of equation

-23y=1

y=1/-23

Therefore the value of y is -1/23
