Explain the process how would you estimate the solution of system of equation to the nearest tenth place
The actual solution must be approximated to the tenth place.
How do you solve an equation to the nearest tenth?
To round the decimal number to its nearest tenth, look at the hundredth number. If that number is greater than 5, add 1 to the tenth value. If it is less than 5, leave the tenth place value as it is, and remove all the numbers present after the tenth place.
To estimate the tenth place, you have to determine the actual solution and the approximate.
Assume the solution to the system of equations is:
(x, y), (1.25, 1)
1.25 is to the hundredth place.
So, the next thing is to approximate 1.25 to 1.3 (the tenth place).
So, we have:
(x, y), (1.3, 1)
Hence, the actual solution must be approximated to the tenth place.

The average amount of money spent for lunch per person in the college cafeteria is $5. 97 and the standard deviation is $2. 25. Suppose that 46 randomly selected lunch patrons are observed. Assume the distribution of money spent is normal, and round all answers to 4 decimal places where possible.
What is the distribution of X? X~ N(_______,_______)
What is the distribution of ¯x? ¯x~ N(______,_____)
For a single randomly selected lunch patron, find the probability that this patron's lunch cost is between $6. 4225 and $6. 5884.
For the group of 46 patrons, find the probability that the average lunch cost is between $6. 4225 and $6. 5884
We determined that the probability of lunch cost is between the above-mentioned value is P (0.2011 < Z < 0.2748)
What is probability and statistics?
Probability is the possibility of happening an event. It is expressed as the ratio of the number of favorable outcomes to the total possible outcome.
We can find probability from a statistical data based on the mean value and standard deviation.
What is the probability of the given data?given, average cost for lunch per person = mean value = $5.97
standard deviation of cost = $2.25
number of samples = 46
assume distribution of money spent is normal.
the probability of a single lunch patron that has a cost between $6.4225 and $6.5884 can be calculated by the following way.
Z-score = (actual price - mean price) / standard deviation
Z-score when actual price is $6.4225.
Z = ($6.4225 - $5.97) / $2.25
Z = 0.2011
Now, Z-score when actual value is $ 6.5884.
Z = ($6.5884 - $5.97) / $2.25
Z = 0.2748
If actual value is denoted by X than the probability is shown as
P (6.4225< X< 6.5884) and P (0.2011< Z< 0.2748)
For the group of 46 patrons the above probability is also the same.

write the equation of the line passing through the point (4, -6) with a slope of 1/2?
Answer:
Step-by-step explanation:
We know that , the equation of line when the slope and the coordinates are given is:
y - y1 = m(x - x1)
where x1 = 4 , y1 = -6 and m = 1/2
therefore, y -(-6) = 1/2(x - 4)
y + 6 = x/2 - 2
6+2 = x/2 - y
8 = x - 2y/2
16 = x - 2y
required equation : x-2y-16=0

Answer:
the median best describes the data
the mean is less than 5 of the data points
the range only describes 2 of the data points
thus the median best describes the data
Step-by-step explanation:
Median is the number in the centre of a set of observations
0. 78, 84,85,90,91,92, the median is 85
range = highest - lowest = 92 - 0 = 92
mean = sum of observations / number of observations = 74.3

What property is illustrated in if ∠a ≅ ∠B ∠B ≅ ∠C then ∠a ≅ ∠CA reflexive property C transitive property B symmetric property d addition property?
The property of congruence illustrated in the statement is the transitive property.
What is transitive property?The transitive property states that if A is congruent to B and B is congruent to C, then A is congruent to C. In other words, if two things are congruent to a third thing, they are also congruent to each other.
here,
In the statement "If AB ≅ DE, EF ≅ DE then AB ≅ EF," AB is congruent to DE, and EF is congruent to DE, so AB must also be congruent to EF according to the transitive property.
The other properties you listed are not applicable in this case. The symmetric property states that if A is congruent to B, then B is congruent to A. The reflexive property states that every object is congruent to itself. And multiplication is not a property of congruence.

What is the degree of polynomial 2 y² Y³ 2y8?
The degree of the polynomial [tex]2yA^2yA^32y^8[/tex] is 15
A polynomial's degree is the sum of the degrees of its monomials with non-zero coefficients. A term's degree is the sum of the exponents of the variables in it, and it is thus a non-negative integer.
The degree of a polynomial is the highest or largest power of a variable in a polynomial equation. The degree denotes the polynomial with the maximum exponential power (ignoring the coefficients).
Consider the following polynomial expression with two variables: [tex]x^3 + 6x^2y^4 + 3y^2+5[/tex]
The polynomial has a degree of 6.
This is because the exponent values of x and y in the second term of the algebraic formula, [tex]6x^2y^4[/tex], are 2 and 4, respectively. We get 6 when we sum the exponent values. As a result, the multivariable polynomial expression has a degree of 6.

Function NotationApplicationStep 1: DefineLet's organize what is given to us in the problem.
We are given a function f, defined as f(x) = x² + 3x - 10.
We are asked to find the values of b and c in f(x - 2) = x² + bx + c.
Step 2: SolveIn order to solve the question, we first must find the full function of f(x - 2):
[tex]\displaystyle\begin{aligned}f(x - 2) & = (x - 2)^2 + 3(x - 2) - 10 \\& = \underbrace{x^2 - 4x + 4}_{\text{FOIL}} + \underbrace{3x - 6}_{\text{Distribute}} - 10 \\& = \boxed{ x^2 - x - 12 } \\\end{aligned}[/tex]
∴ [tex]\displaystyle \boxed{ f(x - 2) = x^2 - x - 12 }[/tex]
Now, we can correlate our variables to the f(x - 2) function by comparing them side-by-side:
[tex]\displaystyle\begin{aligned}f(x - 2) & = x^2 - x - 12 \\& = x^2 + bx + c \\& \Rightarrow \boxed{ b = -1 ,\ c = -12 }\end{aligned}[/tex]
∴ we have found the values of b and c.
Answer∴ the value of b is equal to -1 and the value of c is equal to -12.

A grocer can buy strawberries for $1.38 per pound. What is the constant of proportionality?
It means that the grocer has to pay $1.38 for each pound of strawberries. So the constant of proportionality for this scenario is $1.38
What is proportionality?Proportionality is a mathematical relationship between two variables, where the ratio of one variable to the other is always the same, regardless of the values of the variables. The variables are said to be in proportion if there is a constant of proportionality "k" such that one variable is equal to "k" times the other variable. In other words, if y is proportional to x, the relationship is represented by an equation of the form y = kx, where "k" is the constant of proportionality.
What is constant?A constant is a value that does not change. In mathematical terms, it refers to a value in an equation that remains the same and does not depend on the variables. For example, in the equation y = kx, "k" is a constant. It is a fixed numerical value that relates two variables in a proportionality relationship. Constants can be represented by a number, a letter or a symbol.

What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
We have the interval from x = 1 to x = 2.
To find the function’s average rate of change over the interval from x = 1 to x = 2 is:
We interpreted the interval in the coordinate form.
The curve from (1, 2) to (2, 0) is a straight line.
And the slope of the line is the average rate of change of the function.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (0-2) / (2-1)
m = -2/1
m = -2
Therefore, the average rate of change is -2.
