Answer:

It would be a 3/4 chance that he will pull the right 4 coins.

Step-by-step explanation:

The probability that the first 3 coins are equal to $0.40 will be 1/4

Simon needs to pull out the penny last so that the first three coins add up to $0.40. We assume the coins are wrapped so it is a random choice.

For the first coin, the probability of not pulling a penny is 3/4, similarly, for the second coin, the probability of not pulling a penny is 2/3,

For the third coin, the probability of not pulling a penny is 1/2,

P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

Answer:

El papá de Blanca gasta $1,000 de su sueldo en alimentos.

Step-by-step explanation:

En primer lugar, se designa a la letra S como la cantidad total del salario de la persona.

Sabiendo que el papá de Blanca destina la tercera parte de su salario para comprar alimentos, y que la tercera parte de un número es la división de ese número entre tres, entonces se tiene la expresión:

Alimentos: [tex]A=\frac{S}{3} =\frac{1}{3} *S[/tex]

Ahora sabes que el papá de Blanca destina la mitad de su salario en diversos gastos, y siendo la mitad de un número es la división de ese número entre dos, se obtiene la expresión:

Gastos: [tex]G=\frac{S}{2} =\frac{1}{2} S[/tex]

El papá de Blanca gasta su salario en alimentos y en otros gastos y le sobran $ 500. Esto es expresado mediante:

Alimentos + Gastos + 500 = Salario

Entonces:

A + G + 500 = S

Sustituyendo A y G:

[tex]\frac{1}{3} S+\frac{1}{2} S+500=S[/tex]

Resolviendo:

[tex]\frac{5}{6} S+500=S[/tex]

[tex]500=S- \frac{5}{6} S[/tex]

[tex]500= \frac{1}{6} S[/tex]

[tex]\frac{500}{\frac{1}{6} } =S[/tex]

3,000= S

Entonces el salario del papá de Blanca es de $ 3,000

Reemplazando este valor para el cálculo de su gasto en alimentos es:

[tex]A=\frac{1}{3} *S= \frac{1}{3}* 3,000[/tex]

A= 1,000

El papá de Blanca gasta $1,000 de su sueldo en alimentos.

[tex]g^{-1}[/tex] (x) = [tex]\frac{x+11}{4}[/tex]

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y = 4x - 11 ( add 11 to both sides )

y + 11 = 4x ( divide both sides by 4 )

[tex]\frac{y+11}{4}[/tex] = x

Change y back into terms of x , with x = [tex]g^{-1}[/tex] (x) , thus

[tex]g^{-1}[/tex](x) = [tex]\frac{x+11}{4}[/tex]

Answer:

y = -2x + 3

Step-by-step explanation:

Lets just put the three points together.

(-1, 5) (-4, 11) (-7, 17)

First let's find the slope with y2 - y1/x2 - x1

Plug in using (-1, 5) and (-4, 11)

11 - 5/-4 + 1 = 6/-3 (simplify)

-2 is the slope

Now plug in (-7, 17) in the equation to get b or the y-intercept)

y = mx + b

17 = -2(-7) + b

17 = 14 + b (subtract 14 on both sides)

3 = b

y = -2x + 3

The equation of the line that passes through the points in the table is:[tex]y = -2x +3[/tex]

The line passes through the following points

x (-1, -4, -7)

y (5, 11, 17)

Start by calculating the slope (m) of the line

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{17 - 11}{-4+1}[/tex]

Evaluate the differences

[tex]m = \frac{6}{-3}[/tex]

Evaluate the quotient

[tex]m = -2[/tex]

The equation is then calculated as:

[tex]y = m(x -x_1) +y_1[/tex]

This gives

[tex]y = -2(x+1) +5[/tex]

Open the brackets

[tex]y = -2x-2 +5[/tex]

Evaluate the like terms

[tex]y = -2x +3[/tex]

Hence, the equation of the line is:[tex]y = -2x +3[/tex]

Answer:

x = 4

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 4 from both sides of the equation:

-6x + 4 (-4) = -20 (-4)

-6x = -20 - 4

-6x = -24

Next, divide -6 from both sides of the equation:

(-6x)/-6 = (-24)/-6

x = (-24)/(-6)

x = 4

x = 4 is your answer.

Answer: The kicker must have attempted 44 field goals.

Step-by-step explanation:

If the kicker missed 2 out of every eleven field goals, then this is a division and multiplication problem.

8 ÷ 2 lets us know what number to multiply 11 by, which in this case, is 4.

4 x 11 = 44, and in the context of the question, this would mean that the kicker attempted 44 total field goals.
