From the scrabble information given above, the odds in favor of selecting E is given as 0.073 while the odds against selecting an E is 13.667.

The odds are defined as the chance of the event occurring divided by the probability of the event not occurring. If the chance of an event happening is Y, the probability of it not happening is 1-Y.

Given:

Total number of tiles = 100

Number of E tiles = 12 [See attached image]

The odds in favor of selecting E =

= no of cases in favor of E / no of cases against E

= 12 / ( 100 - 12)

= 6 / 82

= 0.0731707317

[tex]\approx[/tex] 0.073

Given the above,

The odds against selecting E = 82/6

If the tangent of θ equals one (1), the true statement about the right-angled triangle side lengths is that: C. The sides opposite and adjacent to theta are the same length.

In geometry, a tangent is also referred to as a tangent line and it can be defined as a straight line that touches a plane curve at a specific point.

Mathematically, the tangent of an angle is given by this expression:

Tanθ = Opp/Adj

Where:

For this right-angled triangle, the tangent of the angle (θ) is given by:

Table b. doesn't show y as a function of x as is has to two x values for a same y value '100'.

A function, as used in mathematics, is an expression that depicts the relationship between an independent variable (input) and a dependent variable (output), where only one output is possible for each input. In daily life and many professions, functions are useful.

For instance, assuming a constant stride length, a person's distance traveled in an hour is dependent on the number of steps taken. The same individual can extend their walking distance by merely changing the number of steps taken.

Similar to this, the quantity of goods sold may affect the amount of profit a bakery makes. The bakery will generate more revenue by offering more items. The function form of both of these examples is writable. In mathematics, function notation is used to express functions. Such as, f(x) = 3x+ 2

The meaning of y as a function of x is x is y is directly varied with x  that is  y = ax + b, so for every different x there is a unique y too,

But in Table b. there are two y whose values are 100 but the x are different

which is not possible.

Therefore, Table b. doesn't show y as a function of x as is has to two x values for a same y value '100'.

Binary and unary operations are the two most popular forms of operations. Trigonometric functions and negation are examples of unary operations that use only one value. Contrarily, binary operations, which include addition, subtraction, multiplication, division, and exponentiation, only accept two values. Here the same expression will be 5 ∑([tex]([/tex][tex]\frac{1}{3}[/tex][tex])^{i}[/tex]

Mathematical objects other than numbers can be used in operations. Logic operations like and, or, and not can be used to combine the logical values true and false. It is possible to add and subtract vectors. Utilizing the function composition operation, it is possible to combine rotations by first performing the first rotation and then the second. The binary operations union and intersection as well as the unary operation of complementation are operations on sets. Composition and convolution are two operations on functions.

Not all possible values of the domain may be covered by an operation's definition. For instance, it is impossible to square the roots of negative integers or divide by zero in real numbers. An operation's domain of definition, also known as the active domain, is the set of values for which the operation is specified. However, the set of real values obtained by the operation is its codomain of definition, active codomain, image, or range. The set that contains the values created is referred to as the codomain. [failed to verify] For instance, only non-negative numbers are produced by the squaring operation when applied to the real numbers; the set of real numbers is the codomain, but the non-negative numbers are the range.

The function f is positive on the domain (-∞, 3)

The f(x) values corresponding to x-values are given. Also f(x) is a continuous linear function.

If we analyze the function values, the first 3 entries are positive, then from there the function values becomes negative.

Also it is clear from the function values that the function is decreasing from positive values to negative values.

The corresponding x-values for the positive values of the function are x = -3, x = 0 and x = 3.

Since f(x) is continuous linear function, the given x-values and f(x) values are not the only ones there. The domain and images are actually in the form of intervals, but here only certain values are given in the table.

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Let Riley have bought x boxes of  thank you cards and y boxes of get well cards.

Therefore according to the question,
x + y = 5.......(1)
9x + 4y = 30........(2)

Multiplying equation 1  with 4 we get.
4x + 4y = 20.......(a)

Using equation, the number of children and adult tickets sold are 33 and 78 respectively

111 people attend the concert and tickets for adults cost $3.5 while tickets for children cost $2.25 and total receipts for the concert was $347.25.

Therefore, the number of ticket sold for adult and children can be calculated as follows :

let

x = number of children ticket sold

y = number of adult tickets sold.

Therefore, the equation that represent the situation is as follows:

2.25x + 3.5y = 347.25

x  + y = 111

multiply equation(ii) by 3.5

2.25x + 3.5y = 347.25

3.5x + 3.5y = 388.5

subtract equation(i) from equation(ii)

1.25x = 41.25

divide both sides by 1.25

x = 41.25 / 1.25

x = 33

Hence,

y = 111 - 33

y = 78

Therefore,

number of children ticket = 33
