Si en un grupo de 10 personas se va a repartir refrescos de 10 sabores diferentes, y se sabe que hay uno de fresa y uno de piña ¿cuál es la probabilidad que el primero en ser repartido sea de piña y el segundo de fresa?

Answers

Respuesta: 0.011

Explicación paso a paso:

Dado que:

Número de sabor a refresco = 10

Número de sabor a piña = 1

Número de sabor a fresa = 1

P (primero es fresa) = número de sabor a fresa / número total de sabor

P (primero es fresa) = 1/10

P (el segundo es sabor a piña) = número de sabor a piña / número total de sabor

P (segundo sabor a piña) = 1/9

Probabilidades independientes:

P (primero es fresa) * P (segundo sabor a piña)

= (1/10) * (1/9)

= 1/90

= 0.011

Carissa earns $450 per week for a 40 hour work week plus $16.83 per hour for each hour of overtime after 40 hours. Write an equation that would be used to determine her weekly wages where,

Answers

Answer:

450 + 16.83[tex]x[/tex]

x = the number of overtime hours worked.

Answer:

y = 16.83x + 450

Step-by-step explanation:

y - the amount earned

x - the hours worked overtime

450 is a constant, it is a value that is always present, and doesn't change or depend on anything. 16.83 is a coefficient whose value needs to be multiplied by the x value to hold true in the equation.

Answer:

4) (4, 0)

Step-by-step explanation:

I find it useful to graph the inequalities and the points.

The point on the dashed line is not in the solution set. The only point in the doubly-shaded area is (4, 0), choice (4).

Another method of choosing the points is to try them in the inequalities. I find it easier to do the math if the inequalities are written in standard form:

2y < x +8 . . . . . multiply the first by 2

x -2y > -8 . . . . . add -8-2y and swap sides. This is the first inequality.

y ≥ -x +1

x + y ≥ 1 . . . . . add x. This is the second inequality

For the four points in the first inequality, we have ...

1) -5 -2(3) = -11 . . . not greater than -8

2) 0 -2(4) = -8 . . . not greater than -8

3) 3 -2(-5) = 13 . . . greater than -8, satisfies the first inequality

4) 4 -2(0) = 4 . . . greater than -8, satisfies the first inequality

So, the two points that might possibly work are (3, -5) and (4, 0). Here, we try these in the second inequality.

3) 3 -5 = -2 . . . less than 1

4) 4 + 0 = 4 . . . greater than 1, satisfies the second inequality

The only point listed that is a solution to the system is (4, 0), point 4.

A new pair of shoes cost $78. They are on sale for $60.06.

What is the percent of change?

Answers

Answer: 23%

Step-by-step explanation:

From the question, we are informed that a new pair of shoes cost $78 and that they are on sale for $60.06.

The percent of change will be calculated as:

Change/ Cost price × 100

= [(78 - 60.06) / 78] × 100

= (17.94 / 78) × 100

= 0.23 × 100

= 23%

Answer:

Step-by-step explanation:

Since ΔNOP is a traingle, all the angles added up together equal 180 degrees.

(5x-8) + (x-5) + (6x+1) = 180

Now simplify by adding like terms

12x-12 = 180

Solve for x by adding 12 to both sides and then dividing both sides by 12

12x=192

x=16

Once you solved for x, plug it into the angle you need to find.
