A box contains 6 black pens, 4 blue pens, and 7 red pens. Without looking, Clarissa randomly picks a black pen out of the box. I

Irina18 [472]

Answer:

31.35%

Step-by-step explanation:

<h3>Initial reading:</h3>

In the box, there are:

6 Black pens
4 blue pens
7 red pens

Total number of pens in the box = 6 + 4 + 7

= 17

If we count pens as outcomes the total number of possible outcomes are 17.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>New reading:</h3>

Clarissa takes out a black pen from the box.

That reduces the number of black pens by 1 which increases the total number of pens by 1 as well.

So now:

Number of black pens = 6 - 1 = 5 
Total number of pens = 17 - 1 = 16

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>Probability:</h3>

$\boxed{ \mathsf{probability = \frac{favorable \: outcomes}{total \: outcomes} }}$

If we want her to pick up a black pen, and she ends up picking one. So, we can say that the outcome is in our favor.

That makes it,

the number of favorable outcomes = number of black pens

= 5

and total outcomes = Total number of pens

= 16

$\implies\mathsf{probability = \frac{5}{16} }$

For showing it as some percent we'll just multiply the fraction by 100

$\implies \mathsf{ \frac{5}{16} \times 100 }$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

<h3>As a percent:</h3>

$\implies \mathsf{ \underline{ 31.25 \: \% } }$

X=-4y 3x+2y=20 Substitution

nadezda [96]

Answer: y= -2; x = 8

Step-by-step explanation:

X=-4y.......equation 1

3x+2y=20......equation 2

Substitute the value of x into equation 2

3 (-4y) + 2y = 20

-12y + 2y = 20

-10y = 20

Divide both sides by -10

y = 20/-10

y = -2

Substitute the value of y into equation 1 to get the value of x

x = - 4(-2)

x = 8

I hope this helps greatly, please mark as brainliest answer.
