Answer:

\frac{2}{15}

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>
  • We have a bag with 4 white chips and 6 black chips
  • Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : \frac{2}{5}

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : \frac{1}{3}

\frac{2}{5} * \frac{1}{3}

\frac{2}{15}

The equations of two lines are x - 3y = 6 and y = 3x + 2. determine if the lines are parallel, perpendicular or neither.parallel
Mice21 [21]
Start by converting x - 3y = 6 into slope-intercept form:
x - 3y = 6
Subtract x from both sides:
-3y = -x + 6
Divide both sides by -3:
y = (1/3)x - 2
Now compare both equations:
y = (1/3)x - 2
y = 3x + 2
They don't share anything perpendicular or parallel equations would share, so therefore they are neither.

Hope this helps! :)

Four congruent isosceles right triangles are cut from the 4 corners of a square with a side of 20 units. The length of one leg o
yanalaym [24]

Answer:

368 sq. units.

Step-by-step explanation:

We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.

Now, the four isosceles right triangles have one leg equal to 4 units.  

Therefore, the area of four triangles = 4 \times ( \frac{1}{2} \times 4 \times 4) = 32 sq. units.

Now, we have the area of the given square is (20 × 20) = 400 sq. units.

Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
