Answer:

[2, 1]

Step-by-step explanation:

By the Elimination method, you are left with 8x = 16 because -8 and 8 are what are called Additive Inverses, meaning they result in 0⃣; x = 2, plug 2⃣ back into both equations, and you will see that y = 1, making the solution above.

The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Su

Answer:

3.566%

Step-by-step explanation:

The probability formula for a poisson distribution is:

$P( k )=\frac{\lambda^{k}e^{-\lambda}}{k!} \\$

λ is the average of events

e is the euler's number

k is the number of events you want to know the probability

For this :

λ = 8.9 (on average the number of tickets is 8.9 per day)

k = 4 (you need to find the probability that exactly 4 tickets are written per day)

$P( k=4 )=\frac{8.9^{4}e^{-8.9}}{4!}=0,03566 =3.566\%$

Answer:

79.5 + 5.5x = Y

Step-by-step explanation:

Sumo wrestler gained 5.5 kg per month

After 11 month, he weighed 140 kg.

Let x be his current weight.

Then x + 11(5.5) = 140

x = 140 - 60.5

x = 79.5

If Y is the weight of the wrestler after t months, then the linear equation would be:

79.5 + 5.5t = Y
