Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.
What exactly is a linear equation?The formula y=mx+b is used to draw a simple regression graph. The inclination is B, and the y-intercept is m. It is frequently referred to simply as a "simple method combining many variables," despite the fact that the section before it is divided into distinct sections. Bivariate linear equations have two variables. For problems involving linear equations in applications, there are no proven solutions. Y=mx+b, also known as mx+b, provides a number of straightforward formulae.
Here,
Using the distance formula:
sqrt((x - 11)^2 + (-9 - 6)^2) = 17
Simplifying:
sqrt((x - 11)^2 + 225) = 17
Squaring both sides:
(x - 11)^2 + 225 = 289
(x - 11)^2 = 64
Taking the square root:
x - 11 = ±8
x = 11 + 8 or x = 11 - 8
x = 19 or x = 3
Therefore, the values of x that make the equation distance between (11,6) and (x,-9) equal to 17 are x = 19 and x = 3.

Draw a curve to show the effect of chocolatiers offering their chocolates in special red boxes. Label it 2.
Draw a point to show the new equilibrium price and new equilibrium quantity.
The only price at which consumer and producer plans are in agreement is the equilibrium price, which is reached when the quantities of a good that consumers want to buy and a good that producers want to sell are equal.
What is the difference between equilibrium price and new equilibrium quantity?The equilibrium price, which is obtained when the quantity of a good that consumers want to buy (quantity requested) and the quantity of a good that producers want to sell (quantity provided) are equal, is the only price at which consumer and producer plans are in sync. This common quantity is referred to as the "equilibrium quantity".
If supply and demand are balanced in an economy, the equilibrium price will be reached. Thus, the manufacturer can create the same quantity of a good (supply) that consumers can purchase at this price (demand). As a result, supply and demand are met. Additionally, at this time, both buyers and sellers win. In addition, the equilibrium price contrasts with the idea of disequilibrium, in which supply and demand are not equal.
Supply and demand for a good are in equilibrium when the quantity is the same. In order to create economic equilibrium and equilibrium quantity, the supply and demand curves finally cross. This is hypothetically the most effective state the market can achieve and the state to which it naturally tends.

9. Find b so that the vectors v=5i +2j and w=4i+b are orthogonal.
Answer:
b = -10
Step-by-step explanation:
Two vectors are orthogonal if and only if their dot product is zero. The dot product of v and w is given by:
(v · w) = (5i + 2j) · (4i + bj) = 5 * 4 + 2 * b = 20 + 2b.
For v and w to be orthogonal, we need the dot product to be zero, which means 20 + 2b = 0, so:
2b = -20
b = -10
Therefore, b = -10 makes the vectors v and w orthogonal.

The sum of two consecutive integers 157 can be found by using the formula: x + (x + 1) = 157, where x represents the first integer.
Solving for x:
x + (x + 1) = 157
2x + 1 = 157
2x = 156
x = 78
So, the two consecutive integers are 78 and 79. The product of these integers is 78 * 79 = 6162.
Answer:
6162.
Step-by-step explanation:
Let's call the two consecutive integers x and x + 1. We know that their sum is 157, so we can write an equation:
x + (x + 1) = 157
Expanding and solving for x:
2x + 1 = 157
2x = 156
x = 78
So, the two consecutive integers are 78 and 79. The product of these integers is 78 * 79 = 6162.

which of the following will cause ordinary least square (ols) estimates of a simple regression model, y = β0 + β1x + u to be biased?
Answer:
There are several factors that can cause ordinary least square (OLS) estimates of a simple regression model, y = β0 + β1x + u, to be biased:
1. Non-random sampling: If the sample used in the regression analysis is not random, then the OLS estimates may be biased. For example, if the sample only includes people who live in a specific area or only those who are a certain age, then the estimates will not be representative of the population as a whole.
2. Endogeneity: If one of the independent variables in the model is correlated with the error term, then the OLS estimates will be biased. This occurs when there is a omitted variable that is related to both the dependent variable and one of the independent variables.
3. Multicollinearity: When two or more independent variables in the model are highly correlated with each other, it can cause the OLS estimates to be biased. This occurs because the estimates become unstable when the variables are highly correlated.
4. Non-constant variance: If the variance of the errors in the model is not constant, then the OLS estimates will be biased. This occurs when the errors are not homoscedastic.
5. Specification error: If the wrong variables are included or excluded from the model, then the OLS estimates will be biased. This occurs when the model is misspecified.

What is a z-score?The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.
The Z-score is calculated using the formula:
z = (x - μ)/σ
where z: standard score
x: observed value
μ: mean of the sample
σ: standard deviation of the sample
Given data ,
Let the probability that daily production is less than 27.6 liters be represented as P
Now , the equation will be
a)
The observed value of x = 27.6 L
The mean of the sample μ = 39 L
The standard deviation of the sample σ = 5.2 L
Now , z-score is calculated using the formula:
z = (x - μ)/σ
Substituting the values in the equation , we get
z = ( 27.6 - 39 ) / 5.2
z = -2.19231
Now ,the p value from the z table is
P ( x < 27.6 ) = 0.014179
And , the probability is P ( x < 27.6 ) = 0.014179 = 1.418 %
Therefore , the probability that daily production is less than 27.6 liters is given by P = 1.418 %
b)
The observed value of x = 49.4 L
The mean of the sample μ = 39 L
The standard deviation of the sample σ = 5.2 L
Now , z-score is calculated using the formula:
z = (x - μ)/σ
Substituting the values in the equation , we get
z = ( 49.4 - 39 ) / 5.2
z = 2
Now ,the p value from the z table is
P ( x < 49.4 ) = 0.97725
P ( x > 49.4 ) = 1 - P( x < 49.4 ) = 0.02275
And , the probability is P ( x > 49.4 ) = 0.02275 = 2.275 %
Therefore , the probability that daily production is more than 49.4 liters is given by P₁ = 2.275 %

Given that:
The right angled triangle has hypotenuse of 18 units
Its one other side measures 6 units.
The length of unknown side is denoted by length x units.
To find:
Value of x
The Pythagoras theorem states that:
"In a right angled triangle, the square of length of its hypotenuse is equal to sum of square of other two sides' lengths"
Using Pythagoras theorem for given right triangle we have:
Thus, for given right triangle, the value of x is given as:
18²=[tex]x^{2} +[/tex]6²
324=[tex]x^{2}[/tex]+36
[tex]x^{2}[/tex]=324-36
[tex]x^{2}[/tex]=288

A cup of coffee initially at 100°C cools to 80°C in 5 minutes while sitting in a room at constant temperature
28°C. What will be the temperature T of the coffee after 10 minutes?
The equation of line is y = -4x + 100 and the temperature of the coffee after 10 minutes is given by A = 60°C
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the temperature be represented as y
Let the number of minutes be represented as x
Now , the initial temperature is 100°C
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 100 )
Let the second point be Q ( 5 , 80 )
Now , the slope of the line between the points is ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 100 - 80 ) / ( 0 - 5 )
Slope m = 20 / -5
Slope m = -4
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 100 = -4 ( x - 0 )
y - 100 = -4x
Adding 100 on both sides of the equation , we get
y = -4x + 100
Now , when x = 10 minutes ,
y = -4 ( 10 ) + 100
y = -40 + 100
y = 60°C
Hence , the equation is solved and temperature after 10 minutes is 60°C
