The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 292 people entered the park, a

motikmotik

Answer:

112 children

180 adults

Step-by-step explanation:

Let the number of adults = A

Let the number of children = C

A + C =292

4A + 1.5C = 888. solve for A, C

A = 292 - C

4[292 - C] + 1.5C = 888

1,168 - 4C + 1.5C = 888

-2.5C = - 280

C = -280 / -2.5

C = 112 - Number of children

292 - 112 = 180 - Number of adults

Step-by-step explanation:

Step 1: Define

Identify.

$\displaystyle V_P = 2x^3 - 6x^2 + 8x$

$\displaystyle V_C = 27x^3$

Step 2: Find Combined Volume

[Set up] Add: $\displaystyle V_P + V_C = V_{P + C}$
Substitute in variables: $\displaystyle V_{P + C} = 27x^3 + 2x^3 - 6x^2 + 8x$
Combine like terms: $\displaystyle V_{P + C} = 29x^3 - 6x^2 + 8x$

Suppose you choose a marble from a bag containing 6 red marbles , 2 white marbles and 5 blue marbles you return the first marble

algol [13]

Answer:

30/169

Step-by-step explanation:

We need to know how many marbles in the bag

6 red marbles + 2 white marbles + 5 blue marbles = 13 marbles

P (red) = red / total = 6/13

We then put the marble bad so there are still 13 marbles in the bag

P(blue) = blue /total = 5/13

P (red then blue ) = P(red) *P(blue)

= 6/13 * 5/13 = 30/169

Betty has several of the standard six-sided dice that are common in many board games. If Betty rolls one of these dice, what is

pashok25 [27]

Answer:

16.7%

Step-by-step explanation:

Each of the six faces of a six-faced die shows one of the numbers: 1, 2, 3, 4, 5, 6.

A roll of a die is equally likely to land on any face, so the total number of possible outputs is 6, corresponding to the number of faces on the die.

The desired outcome here is 3, meaning the face that shows the number 3. Only one face has the number 3, so the number of desired outcomes is 1.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

p(3) = 1/6 = 0.16666... = 16.7%
