Mr. Collins is constructing a fence around his property. He already has 25 sections up and plans to add 8 sections each Saturday

AURORKA [14]

Hi!

So, we know the Mr. Collins already has 25 sections. So let's write an equation.

25 + 8s
(s = Saturday)

Now our value for s in this equation is 15. So put in the value..

25 + 8 · 15
25 + 120
145

The answer is 145

Hope this helps! :)

Ariana's password consists of 1 letter followed by 2 digits. What is the probability of correctly guessing Arabella's password?

AleksandrR [38]

Answer:

1/2600 = 0.00038

Step-by-step explanation:

To find this probability, we first need to find how many ways we can fill each letter and each digit.

The letter has 26 different values, and each digit has 10 different values, so to find the total number of passwords, we just need to multiply the possibilities for each letter and digit:

Total cases = 26 * 10 * 10 = 2600

So the probability of correctly guessing is 1/2600 = 0.00038

Viefleur [7K]

Answer:

40 packages from Fred Motors
20 packages from Admiral Motors
40 packages from Chrysalis

Step-by-step explanation:

I would formulate the problem like this. Let f, a, c represent the numbers of packages bought from Fred Motors, Admiral Motors, and Chrysalis, respectively. Then the function to minimize (in thousands) is …

objective = 500f +400a +300c

The constraints on the numbers of cars purchased are …

5f +5a +10c >= 700

5f +10a +5c >= 600

10f +5a +5c >= 700

Along with the usual f >=0, a>=0, c>=0. Of course, we want all these variables to be integers.

Any number of solvers are available in the Internet for systems like this. Shown in the attachments are the input and output of one of them.

The optimal purchase appears to be …

40 packages from Fred Motors
20 packages from Admiral Motors
40 packages from Chrysalis

The total cost of these is $40 million.
