The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water
erik [133]

Answer: A

Step-by-step explanation:

In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.

The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Su
katrin [286]

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\%

-BARSIC- [3]

Answer:

12/(7-4) + 5 * 3 = 19

Step-by-step explanation:

Given

Untrue Expression: 12 ( 7 − 4 ) + 5 3 = 19

Signs: +−×÷

Required

Use the given signs to make the equation true.

To solve this, the trial and error method will be adopted.

The trial and error method involves trying series of sign combinations in the given expression; whichever works is the right answer.

So, after few attempts the following makes the equation true

12/(7-4) + 5 * 3 = 19

To check if it's true or not; we simply expand the expression on the left hand side. This gives

12/3 + 5 * 3 = 19

4 + 5 * 3 = 19

4 + 15 = 19

19 = 19.

Hence, the sign combinations used in 12/(7-4) + 5 * 3 = 19 is correct.
