Answer:

0.5

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X higher than x is given by the following formula.

P(X > x) = \frac{b - x}{b-a}

The mail arrival time to a department has a uniform distribution over 5 to 45 minutes.

This means that a = 5, b = 45.

What is the probability that the mail arrival time is more than 25 minutes on a given day?

P(X > 25) = \frac{45 - 25}{45 - 5} = 0.5

So the probability that the mail arrival time is more than 25 minutes on a given day is 0.5.

Reil [10]

Equation: 8p = 12.25

Ounces of food per puppy: Approximately 1.5


Mika has 12.25 ounces of puppy food to feed 8 puppies.

All 8 puppies need the same amount.

So, how many ounces of food will each puppy get?

That's where I come in.

I guess.


To find out how many ounces of food each puppy gets, you must make an equation.

Luckily for you, I've already made an equation of this in my head before I even finished typing this sentence.

You can use my equation if you want.

Equation: 8p = 12.25

Divide both sides by 8 to get approximately (hence I rounded to the nearest tenth) 1.5 ounces of food per puppy.

Now you've got some nice work to show your teacher and you've got the correct answer. Well done.
