Travka [436]

Answer: 20%

Step-by-step explanation:

The probability that a randomly selected marble will be pink can be found by the formula:

= Number of pink marbles / Number of total marbles

= 4 / 20

= 20%

There is a 20% chance that if you pick a marble, it will be pink.

What is the slope of the line through (-1,4) and (5,2)

butalik [34]

Answer:

Slope (m) = $-\frac{1}{3}$

Step-by-step explanation:

Use the following equation:

Slope $(m) = \frac{y_2 - y_1}{x_2 - x_1}$

Let:

$(x_1 , y_1) = (-1 , 4)\\(x_2 , y_2) = (5 , 2)$

Plug in the corresponding numbers to the corresponding variables:

$m = \frac{2 - 4}{5 - (-1)} = \frac{2 - 4}{5 + 1} = \frac{-2}{6}$

Simplify. Divide common factors from both the numerator and denominator:

$\frac{(-\frac{2}{6})}{\frac{2}{2} } = -\frac{1}{3}$

$-\frac{1}{3}$ is your answer.

Answer: $x=45$

Simplify both sides of the equation

$x+1.2x+1=100$

$(x+1.2x)+(1)=100$ (Combine Like Terms)

$2.2x+1=100$

Subtract 1 from both sides

$2.2x+1-1=100-1\\2.2x=99$

Divide both sides by 2.2

$2.2x/2.2=99/2.2$

$x=45$
