By answering the above question, we may state that The chance of probability drawing a non-red marble is just the probability of drawing a non-red marble. As a result, the probability is 209/210.
What is probability?Probabilistic theory is a branch of mathematics that calculates the likelihood of an event or proposition occurring or being true. A risk is a number between 0 and 1, with 1 indicating certainty and a probability of around 0 indicating how probable an event appears to be to occur. Probability is a mathematical term for the likelihood or likelihood that a certain event will occur. Probabilities can also be expressed as numbers ranging from 0 to 1 or as percentages ranging from 0% to 100%. In relation to all other outcomes, the ratio of occurrences among equally likely alternatives that result in a certain event.
The likelihood of drawing a red marble is 210, which indicates that one red marble is drawn out of every 210 in the jar. This probability may be expressed as a fraction:
P(Red) = 1/210
The likelihood of drawing a non-red marble is the inverse of the probability of drawing a red marble:
P(Not Red) = 1 minus P(Red) = 1 minus 1/210 = 209/210
As a result, the chance of drawing a marble that is not red is 209/210.
The chance of drawing a non-red marble is just the probability of drawing a non-red marble. As a result, the probability is 209/210.

Tara uses 6.6 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
1.65 pints
Step-by-step explanation:
If Tara used 6.6 pints of white and blue paint combined, and 3/4 of that amount is white paint, then we can find the amount of white paint she used by multiplying 6.6 by 3/4:
6.6 x 3/4 = 4.95
So Tara used 4.95 pints of white paint to paint her bedroom walls.
To find out how much blue paint she used, we can subtract the amount of white paint from the total amount of paint:
6.6 - 4.95 = 1.65
Therefore, Tara used 1.65 pints of blue paint to paint her bedroom walls.

What is the x and the y Intercept?
For the given function the intercepts are:
x-intercept: x = -4
y-intercept: y = 12.
How to find the intercepts for the given function?Here we have a table that defines a function, and we want to find the intercepts of said function.
We can assume it is linear, then the slope of the function will be given by:
a = (9 - 3)/(-1 + 3) = 6/2 = 3
The linear function is like:
y = 3x + b
To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.
18 = 3*2 + b
18 = 6 + b
18 - 6 = b = 12
The linear function is:
y = 3x + 12
The x-intercept is the value of x when y = 0
0 = 3*x + 12
-12 = 3x
-12/3 = x = -4
And the y-intercept is the value of y when x = 0.
y = 3*0 + 12

What is the principal square root? And why is it used when solving radical
polynomials?
Answer:
The principal square root of a non-negative real number is the positive square root. For example, the principal square root of 25 is 5, since 5^2 = 25.
When solving radical polynomials, the principal square root is used because it is the most commonly used square root. In many contexts, including mathematical and scientific calculations, the principal square root is the default choice unless otherwise specified. Additionally, when working with radical expressions, we often simplify expressions by taking the principal square root, as it can help us to simplify calculations and express answers more clearly.

What is triangle inequality theorem?The Triangle is a polygon with three line segments as its boundaries. That is the tiniest polygon imaginable. Three vertices, three internal angles, and three sides make up a triangle.
The triangle inequality theorem explains the connection between a triangle's three sides. This theorem states that for every triangle, the sum of the lengths of the first two sides is always higher than the length of the third side. In other terms, this theorem states that a straight line is always the shortest distance between any two places.
Using the triangle inequality theorem we have:
8 + 12 > x
x + 8 > 12
x + 12 > 8
20 > x
x > 4
x > -4
Therefore, the range of lengths Brett can use for the third piece of steel is 4 in. < x < 20 in.

Step-by-step explanation:
To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):
x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)
Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:
x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7
Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.
Note that this expression is defined for all values of x and y except for x=0.

What is a solid figure?A solid figure is a three-dimensional geometric shape that has length, width, and height. It is also called a three-dimensional or 3D figure. Some examples of solid figures include cubes, spheres, cylinders, cones, and pyramids.
Solid figures are different from two-dimensional shapes, which only have length and width. In contrast, solid figures have depth or thickness, making them more complex and interesting.
Solid figures can be classified based on their properties, such as the number of faces, vertices, and edges they have. For example, a cube has six faces, eight vertices, and 12 edges, while a sphere has no faces, vertices, or edges.
