Step-by-step explanation:
A bag contains 4 white balls, 6 yellow balls, and 5 red balls. In how many ways can 6 balls be chosen if there must be 2 balls of each color? Which of the following combination notation will best represent the problem? Help!
Answer:
4C2 * 6C2 * 5C2
Step-by-step explanation:
White balls = 4
Yellow balls = 6
Red balls = 5
In other to select a total of 6 balls, of which there must be 2 balls each of color white, yellow and red :
That means :
2 red balls from 5 red balls = 5C2
2 balls for 6 yellow balls = 6C2
2 balls from 4 white balls = 4C2
To obtain the number of possible combinations, take the product of the three combinations :
4C2 * 6C2 * 5C2
If bag contains 4 white balls, 6 yellow balls, and 5 red balls then 6 balls can be chosen if there must be 2 balls of each color in 900 ways
What are permutation and combination?permutation is way of selecting and arranging things while combination is way of selecting things .
Given that bag contains 4 white balls, 6 yellow balls, and 5 red balls
we have to select 6 balls
it's given that there must be 2 balls of each color
So here's how we can select them
2 white balls ,2 yellow balls and 2 red balls
So we have to select 2 white balls out of 4 white balls ,2 yellow balls out of 6 yellow balls and 2 red balls out of 5 red balls
so number of ways of selecting
[tex]{4 \choose 2} \times {6 \choose 2}\times {5 \choose 2}[/tex]
[tex]=6\times15\times10\\\\=900[/tex]
If bag contains 4 white balls, 6 yellow balls, and 5 red balls then 6 balls can be chosen if there must be 2 balls of each color in 900 ways

Answer:
( C ) 428.1 ft²
Step-by-step explanation:
Alright, we know the surface area of a shape is the area the entire outside covers. So, we just need to find the areas of each side and add them together.
Let's start with the two rectangular sides. The dimensions of both of these are 10×12. The area of rectangles can be calculated by multiplying the length and width, so let's do that. Then, we will multiply this answer by two, so we have the areas of both rectangles.
10 · 12 = 120
120 · 2 = 240
The area of the two rectangular sides is 240 ft². We have 3 sides left to solve for.
Next, we will find the area of the triangular sides. Again, we will multiply the answer by two so we have the area of both. The area of the triangle can be found by multiplying [tex]\frac{1}{2}[/tex] the width by the height.
4.5 · 8.9 = 40.05
Multiply this by two for the area of both sides.
40.05 · 2 = 80.1
The area of the triangle sides is 80.1 ft².
The last side is also a rectangle, with the dimensions 9×12.
9 · 12 = 108
The bottom side has an area of 108 ft².
Now, we can add the areas together.
240 + 80.1 + 108 = 428.1
The surface area of the shape is 428.1 ft². The answer is C.
I hope this helps ^^
Good luck :)

Answer:
XZ = 42
Step-by-step explanation:
By the property of similar triangles,
"If two triangles are similar, their corresponding sides will be proportional."
By applying the property of similarity in ΔABC and ΔXYZ,
[tex]\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}[/tex]
[tex]\frac{4}{24}=\frac{8}{48}= \frac{7}{XZ}[/tex]
[tex]\frac{1}{6}= \frac{7}{XZ}[/tex]
XZ = 42
Therefore, length of unknown side XZ = 42 units.

With the number set: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13}, what is the probability of choosing an even
number?
A) ≈ 6%
B) ≈46%
C) ≈54%
D) ≈50%
Answer:
b
Step-by-step explanation:
6 of the numbers are even from a total of 13
6/13 is roughly 46%
Answer:
The probability of choosing a number is ≈46%.
Step-by-step explanation:
What is probability?
Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty.
The number set is:
{1,2,3,4,5,6,7,8,9,10,11,12,13}
The even numbers is:
{2,4,6,8,10,12}
Total outcomes = 13
Number of possible outcomes = 6
The probability of the outcome is:
[tex]P(E)=\frac{6}{13} *100\\ =46.153%[/tex]
≈46%
Hence, the answer is option B.

Answer:
175
[tex] {cm}^{3} [/tex]
Step-by-step explanation:
25×7=175
Answer:
175cm3
Step-by-step explanation:
How to find the volume
In math, volume is the amount of space in a certain 3D object. For instance, a fish tank has 3 feet in length, 1 foot in width, and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.
Multiply 25cm2 and 7cm
Therefore, the answer is 175cm3

What is a simpler form of (2x²-3x+1)(x-3)?
Answer:
Step-by-step explanation:
(2x² - 3x + 1 )(x - 3) = (2x² - 3x + 1)*x + (2x² - 3x + 1)*(-3)
= 2x²*x - 3x*x + 1*x + 2x²*(-3) - 3x*(-3) + 1*(-3)
= 2x³ - 3x² + x - 6x² + 9x - 3
= 2x³ - 3x² - 6x² + x + 9x - 3 {Combine like terms}
= 2x³ - 9x² + 10x - 3

4, Give a pair of inequalities that describes
the set of all points in the first quadrant
Answer:
x > 0
y > 0
Step-by-step explanation:
The first quadrant is the quadrant formed by the positive x-axis and the positive y-axis.
And we know that all the elements in this quadrant are larger than zero.
Then, a point (x, y) is on the first quadrant only if:
x > 0
y > 0
Note that we ignore the points with x = 0 or y = 0, this is because these points are shared between quadrants, and these points are not defined as belonging to any quadrant.
