He has 10 choices for the 1st digit.
He has  9  choices for the 2nd digit.
He has  8  choices for the 3rd digit.
10x9x8 means he has one in 720 probability.

3 digits, there are 10 digits: 0, 1, ..., 9. Order matters 123 is a different code than 321, then

Possible codes: 10 * 9 * 8 = 720, since it can not be repeated.

If he chooses one code:

P = 1 / 720 = 0.138 %

Probably, 1/720 is the best way to write the answer since it shows what it means.

What is the value of g?<br> 3/5g - 1/3 = -10/3
marshall27 [118]
3/5g-(1/3)=(-10/3)
move the 1/3 over
3/5g=(-10/3)+(1/3)   (notice the + sign)
3/5g= (-9/3)
3/5g=(-3)
move the 3/5 over (divide)
g= (-3/(3/5))
g= (-3x5/3)
g= -15/3
g= -5

The Highly Improbable Foods Company makes vegetarian versions of burgers, hot dogs, and chicken wings, and they offer two platte
choli [55]

Answer:

  $1020

Step-by-step explanation:

Let x and y represent the numbers of Platter A and Platter B the organizer needs to purchase, respectively. The given conditions can be summarized as ...

  x + 2y ≥ 80 . . . . . . 80 or more hamburgers are required

  3x + y ≥ 95 . . . . . . 95 or more hot dogs are required

  5x +8y ≥ 380 . . . . 380 or more chicken wings are required

  16x +20y = c . . . . . c must be minimized

__

It is useful to graph these inequalities, and look for the vertex of the feasible region that is closest to the origin. That vertex is (x, y) = (20, 35). The other vertex that is close to the origin is (60, 10). The cost of that order would be $1310.

The value of an order of 20 Platter A and 35 Platter B is ...

  20×$16 +35×$20 = $320 +700 = $1020

The minimum cost of the picnic food is $1020.
