Answer: 6/7

Step-by-step explanation:

If the pen is not red, it must be either black or blue.

Therefore, the probablity is (6+6)/(6+6+2)

= 12/14

= 6/7

Find the area of the shaded portion in the square. Show all work for full credit.

kumpel [21]

Well, what I would do [not sure if it's the correct way], is use the white area as a sector of a circle. The top right of the box is the center of the circle, so the radius is 6.
Then, by the white portion being one quarter of the circle (90° out of 360°), I could calculate the that pink shaded region = the total square (6×6) minus the white sector.
So area (A) of white sector (s): A(s) = 1/4×pi×r^2
$A(s) = \frac{\pi {r}^{2} }{4} = \frac{\pi \times {6}^{2} }{4} \\ A(s) = \frac{36\pi}{4} = \frac{9\pi}{1} = 9x3.142 \\ A(s) = 28.27$
36 - 28.27 = 7.73

The required probability is
a) both are cups is 0.05

b) At least one cup is 0.19

c) One is a cup and the other is a sword is 0.06

<h3 /><h3>What is probability?</h3>

Probability can be defined as the ratio of favorable outcomes to the total number of events.

a) for both are cups

P= 12*11/48*47
p = 0.05

b) for At least one cup
p = 12*36/48*47
p = 0.19

c) for One is a cup and the other is a sword
p = 12*12/48*47
p = 0.06

Thus, the required probability is 0.05, 0.19, 0.06

Which system of inequalities has a solution set that is a line?

Korolek [52]

We're going to solve each of the systems to determine the solution.

<u>System $1$ </u>

$x+y \geq 3\\ x+y \leq 3$

using a graph tool

the solution is the line $x+y=3$

see the attached figure N $1$

<u>System $2$ </u>

$x+y \geq -3\\ x+y \leq 3$

using a graph tool

the solution is the shaded area

see the attached figure N $2$

<u>System $3$ </u>

$x+y > 3\\ x+y < 3$

using a graph tool

The system has no solution

see the attached figure N $3$

<u>System $4$ </u>

$x+y > -3\\ x+y < 3$

using a graph tool

the solution is the shaded area

see the attached figure N $4$

therefore

<u>the answer is</u>

<u>System $1$ </u>

$x+y \geq 3\\ x+y \leq 3$
