fff is a random variable in a game of luck
A random variable is a formula that gives each result in a sample space a numerical value.
There are two types of random variables: discrete and continuous. If a random variable only takes specified values inside an interval, it is said to be discrete. It is continuous if not.
We typically use capital letters, such X and Y, to designate the random variables
A random variable must be measured in order to be able to assign probabilities to a set of potential values. It is evident that the outcomes depend on a number of unpredictable physical elements.
According to the question,
In a game of luck, a turn consists of a player rolling 777 six-sided dice and counting how many of the dice show a 555. Let fff be the number of dice showing a 555 in a turn.
Here, fff is a Random variable.

What is Expression ?
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)
According to question
The total cost of the rice = 6b
The total cost of the bean = 4r
The total cost of the rice and bean Gabriel bought = 6b + 4r
The total cost after the return = (6b 4r) – (2b + r)
Simplifying
⇒ (6b + 4r) – (2b + r)
⇒ (6b + 4r) – 2b - r
⇒ 6b + 4r – 2b - r
⇒ 6b – 2b + 4r - r
⇒ 4b + 3r
hence, The expression after simplifying is 4b + 3r

The missing terms will be 0.5, 2, and 7.5 respectibily.
What is equivalent ratio?
The concept of a ratio in mathematics is the divisional comparison of two quantities, the antecedent and consequent. As an illustration, each ingredient must be added according to a ratio during cooking. So, we may argue that a ratio is employed to represent one quantity as a portion of another. The ratio can be written as a fraction as well. If the ratio a:b is a fraction, its form is a/b. As a result, it is simple to compare two or more equivalent ratios expressed as equivalent fractions.
1st ratio is 8:16 = 1/2
So the following terms will be 1:0.5
For 4 it will be 4:2.
For15 it will be 15:7.5.
Hence, The missing terms will be 0.5, 2, and 7.5 respectibily.

Describe the end behavior of the function -2x^3-13x^2+8x+52
Answer:
[tex]\text{as x} \to \infty, \ \text{y} \to -\infty\\\\\text{as x} \to -\infty, \ \text{y} \to \infty[/tex]
Rises to the left; falls to the right
============================================================
Explanation:
The leading term is what determines the end behavior of any polynomial function.
Given polynomial: -2x^3-13x^2+8x+52Leading term: -2x^3The leading term has the largest exponent. The other terms will have no effect on the end behavior.
As x gets really large in the positive direction, so does x^3. But the -2 out front will flip to have y go to negative infinity.
Therefore: [tex]\text{as x} \to \infty, \ \text{y} \to -\infty[/tex]
We can informally think of this as "falls to the right".
---------------------------
As x heads to the left, x^3 becomes further negative. But -2 out front makes -2x^3 to be positive.
So [tex]\text{as x} \to -\infty, \ \text{y} \to \infty[/tex] aka "rises to the left".
Whatever x does, y does the opposite. If x goes positive, then y goes negative and vice versa.
-------------------------
The end behavior is therefore
[tex]\text{as x} \to \infty, \ \text{y} \to -\infty\\\\\text{as x} \to -\infty, \ \text{y} \to \infty[/tex]
x and y are opposite.
We can summarize that notation as saying "rises to the left, falls to the right".

twice a number is equal to negative four. which equation could be used to find the number? 2 n - 4 2 n
Twice a number is equal to negative four :
2n = -4
Equation:
An equation is a formula that expresses equality by connecting two expressions with an equal sign '='. Equations and their cousins in other languages may have subtly different meanings. For example, in French an equation is defined as containing one or more variables, but in English any formula in its proper form consisting of two equations joined by an equal sign is an equation.
The equation resembles a weighted scale. When two bowls have the same weight (such as grain), the two weights balance the scale and are said to be equal. If you remove a certain amount of grain from one pan of the scale, you must remove the same amount of grain from the other pan to keep the scale balanced. More generally, the equation remains in equilibrium if the same operation is performed on both sides.
According to the question:
If you wanted to solve your equation:
2x = -4
⇒ 2x/2 = -4/2
Divide both sides by 2

Speed = Distance ÷ Time
Distance = Speed × Time
d = 10 × 15
d = 150 m
Thus, The speed of the object is 150 m.
Answer:
d=150m

write a polynomial function f of least defgree that has rational coefficients, a leading coefficient of 1, and the given zeros
A polynomial function f is equal to x^3- 11x^2+41x- 51 of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros.
The degree of this polynomial is 3 and the leading coefficient is 1. Three zeros are 3, 4+i, 4-i bc, and a-bi if a+bi is zero, also known as the conjugate postulate. With this information, we can say that the factors are (x-3)(x-(4+i) )(x-(4-i)).
When we start multiplying, we group like this
(x-3)( (x-4) + i )( (x-4) -i )
Multiply the second two factors first.
(x-4)^2 - (i)^2 [This is the difference of squares (a+b)(a-b)].
We know that
i^2 = -1
= x^2 -4x -4x +16 - (-1)
= x^2-8x+16+1
= x^2 -8x +17
Don't forget (x-3).
Solving complete factors
(x-3)(x2-8x+17)
= x^3 -8x^2 +17x -3x^2 +24x -51
= x^3-11x^2+41x-51
This is the final equation of the polynomial.

Confidence interval definition:A confidence interval in frequentist statistics is a range of estimates for an unobserved parameter. The most common confidence level for computing confidence intervals is 95%, however other levels, including 90% or 99%, are sporadically employed.
Here ,
In this given problem we can see confidence interval has 0 in it.
So,
Since the confidence interval comprises 0, the null hypothesis should be rejected.
When the p-value exceeds the level of significance, the null hypothesis is only rejected.
Since alpha=0.05 in this case, the p-value must be higher than 0.05.

A movie theater ha a eating capacity of 151. The theater charge $5. 00 for children, $7. 00 for tudent, and $12. 00 for adult. There are half a many adult a there are children. If the total ticket ale wa $ 1086, How many children, tudent, and adult attended?
According to the given statement, there were 58 children, 29 adults and 64 students.
What is an equation?Algebraically speaking, an equation is indeed a statement that establishes the equivalence of two mathematical equations.
Briefing:Let there be x number of children, y number of students and x/2 number of adults. Forming the first equation based on number of students -
x + y + x/2 = 151 : Equation 1
Multiply equation 1 with 2
2x + 2y + x = 302 : Equation 2
3x + 2y = 302 : Equation 3
y = (302 - 3x)/2 : Equation 4
Forming second equation based on cost -
5x + 7y + 12x/2 = 1086 : Equation 5
Rewriting this equation
5x + 7y + 6x = 1086 : Equation 6
11x + 7y = 1086 : Equation 7
Keep the value of y from equation 4 in equation 7
11x + 7(302 - 3x)/2 = 1086
11x + (2114 - 21x)/2 = 1086
22x + 2114 - 21x = 2172
x = 2172 - 2114
x = 58
Now,
y = (302 - 3x)/2
y = (302 - 3×58)/2
y = 128/2
y = 64
Number of adults = 58/2
Number of adults = 29
Thus, there were 58 children, 29 adults and 64 students.

Yes, the given expressions are equivalent.
What is the equivalent expression?
Expressions that are equivalent do the same thing even when they have distinct appearances. When we enter the same value for the variable, two algebraic expressions that are equivalent have the same value.
We have,
9(4 - x)

The measure of each of the acute angles of the right triangle is 32° and 58°.
A right triangle is a kind of triangle which has a right angle (90°) and two acute angles (less than 90°).
Let x = measure of one of the acute angles
If the measure of one acute angle of a right triangle is 6 less than twice the measure of the other acute angle, then
measure of the other acute angle = 2x - 6
The sum of all the angles of any triangle is equal to 180°. Hence,
90° + x + 2x - 6 = 180°
Solve for the value of x.
3x = 96
x = 32
