The probability that a ball is not red is 3/5 and the probability that the ball is red or white is 2/3 .
Mathematical descriptions of the likelihood that an event will happen or that a proposition is true are dealt with in the discipline of mathematics known as probability.
The probability of an event is a number between 0 and 1, where 1 denotes a certainty and 0 denotes an impossibility of the event.Simply put, probability is the likelihood that something will occur. We may discuss the chances of various outcomes when we are unsure of how an event will turn out.Statistics is the study of events subject to probability.In the given question there are 6 red balls, 4 white balls, and 5 blue
balls.
Total number of balls = 6+4+5 = 15 balls (sample space)
Red balls = 6
Not red balls = 15 - 6 = 9
Probability that the ball is red = 9/15 = 3 /5
Red and white balls = 6 + 4 =10
Probability that the ball is red or white = 10 / 15 = 2 / 3
Hence the probability that a ball is red or white is 2 / 3.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other. Congruent refers to things that are exactly the same size and shape.
Explain about congruent?
For these items, the word equal is frequently used in place of congruent. If two line segments are the same length, they are said to be congruent. If two angles have the same measure, they are said to be congruent. If two circles have the same diameter, they are congruent.
While equality deals with numbers, congruence deals with shapes (also known as objects). Neither "two shapes are equal" nor "two numbers are congruent" are statements that you make. If one shape can be perfectly superimposed on the other, then two shapes are said to be congruent. While equality deals with numbers, congruence deals with shapes (also known as objects).
Gestures are logical and consistent with what is being spoken. Despite not being the same, both ideas are entirely consistent. We play a game, say things we don't mean, and act contrary to our ideals. The choice is more challenging if the hip appears to be in congruence even with the

Rachel sketches the graph of quadratic function that never crosses the X axis. which statement is true concering the roots of the function?
SOLUTION
Given the question in the image, the following are the solution steps to answer the question.
STEP 1: Define a quadratic equation that does not passes through the x-axis
When a quadratic function never crosses the x-axis, then it has no real roots or solutions. Hence, the discriminant must be negative. meaning the solutions are imaginary/complex.
Hence, the answer will be:
The function has two imaginary roots

It is given in the question that at the clothing store T-shirts are on sale, 3 for $10. A customer at the store says that one T-shirt should cost $7 at this rate.
We have to find the error made by the customer while calculating the rate of a T- shirt.
To find the rate of a shirt we will divide the number of shirts by the total amount.
Hence, the rate of a shirt will be $ 10/3
But the customer subtracted 3 from 10 to get $ 7 as the rate of a T-shirt.
Hence, the customer subtracted 3 from 10 instead of dividing 3 by 10.

After solving the equations we can conclude that the two numbers are 265 and 137.
What exactly are equations?An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values.such as 3x + 5 = 15 as an example.There are many different types of equations, including linear, quadratic, cubic, and others.So, let the first number be 'x' and the second is 'y'.
Now, the two equations can be formed as:
x + y = 402x - y = 128Merge equations as follows:
x + y - 402 = x - y - 128x - x + y + y = -128 + 4022y = 274y = 137So x will be:

A Shopper has $140 to spend. The shopper wants to buy shirts and hats. Each shirts coats $21, and each hat cost $16. What combination of shirts and hats maximizes the amount of money the shopper can spend
The combination of two shirts and six hats will maximize the amount of money the shopper can spend.
What are Mathematical Inequalities?An inequality results from the comparison of two or more algebraic expressions using the symbols <, > ≤, or ≥. They are mathematical expressions with unequal sides.
Let's assume x is the number of shirts and y is the number of hats brought then,
Total amount spend = 21x + 16y
It is given that the total amount the shopper can spend is $140.
So, 21x + 16y ≤ 140,
As x and y are the number of shirts and the number of hats so x and y will assume positive integral values only, to find out the values of x and y plot the region 21x + 16y ≤ 140 with x ≥ 0, y ≥ 0 as shown in the graph.
From the graph, it is clear that the highest integer value which is close to the boundary of 21x + 16y ≤ 140 is x = 2 and y = 6.
The amount spend when x = 2 and y = 6 is 21(2) + 16(6) = 138
Hence, two shirts and six hats will maximize the amount of money the shopper can spend.

Explain if there is or is not a universal test point that can be used for testing the shading for a linear inequality
Answer:
no universal test point
Step-by-step explanation:
You want to know if there is or is not a universal test point that can be used for testing the shading for a linear inequality.
Test pointThe purpose of a test point for the graph of an inequality is to determine whether the shaded area includes the test point or not. A single inequality will divide the universal set into two parts: one part that is the solution set, and one part that is not the solution set.
Non-boundary point(s)A point that is well inside the solution set (or not-a-solution set) will tell you which side of the boundary is shaded. Any point that always meets that requirement could be considered a universal test point.
Boundary point(s)The boundary point(s) between these sets may or may not be shaded, but its(their) shading, or lack of it, will not tell you which half of the universal set is the solution set. That is, any point that falls on the boundary of the solution set is not a suitable test point.
The boundary can be anywhere, so there is no single universal test point.
__
Additional comment
A set of three non-collinear points can be considered to be a universal test set. Together, they can tell you which part of the universal set is the solution set. At most, the boundary line can pass through two of them, so the third can tell you which half of the universe it lies in.
