Answer:

The cost of Jelly Beans = $ \frac{5}{4} $

The cost of Trail Mix      = $ \frac{9}{4} $

Step-by-step explanation:

Given the cost of 6 pounds of Jelly Beans and 2 pounds of trail mix is $12.

Also, the cost of 3 pounds of Jelly Beans and 5 pounds of Trail mix is $15.

Call the cost of one pound of Jelly beans as J

And cost of one pound of Trail Mix as T.

Now, converting the given data to mathematical form, we would have:

$ 6J + 2T = 12  $

Dividing through out by 2 we have:

$ 3J + T = 6 \hspace{15mm}  .....(1) $

$ 3J + 5T = 15 \hspace{15mm} ....(2) $

To solve (1) and (2), subtract the two equations which will give us:

$ -4T = - 9 $

⇒                                            T = 9/4

Substituting the value of T in (1), we have:

$ 3J = 6 - \frac{9}{4} $

$ \implies 3J = \frac{24 - 9}{4} = \frac{(3)(8 - 3)}{4} = \frac{5}{4} $

∴                                               J  = 5/4

Hana is playing a virtual reality game in which she must toss a disc to land on the largest triangular section of the board. If
svetoff [14.1K]

Answer:

Her probability of success is 1/2

Step-by-step explanation:

Firstly, we have to calculate the area of the entire board

That would be the rectangle of the measure 50 cm by 40 cm

We have the area as the product of this two

That would be 50 * 40 = 2,000 cm^2

Now, the value calculated is the area of the entire possible landing area

Secondly, we need to get the area that counts as a success

that would be the area of the triangle that has a base of 50 cm and a height of 40 cm

The area of this is the product of the two divided by 2

we have this as ;

50 * 40 * 1/2 = 1,000 cm^2

So, her probability of success is simply the area of the triangle divided by the area of the rectangle

= 1000/2000 = 1/2

  • Boy = 12

⇒ Probability = Number of favorable outcomes ÷ Total number of possible outcomes

  • P(Freshman | Boy) = freshman/total boys
  • P(Freshman | Boy) = 4/12
  • P(Freshman | Boy) = 1/3
