Finding the line that fits a set of data points the best is done using the linear regression approach. We can utilize the following procedures to apply linear regression to find an equation that would most effectively predict a fair home price depending on the square footage of the home:

Step 1 :The square footage of the house should be on the x-axis and the house's price in thousands should be on the y-axis of the graph you create in step one.

Step 2: Using the slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept, determine the equation of the line of best fit.

Step 3 :Find the slope and y-intercept by substituting the comps data into the equation in step three.

Step 4: The line of best fit has the equation y = mx + b, where m is the line's slope and b is its y-intercept.

Step 5: We must use the formula m = (NΣ(xy) - (Σx)(Σy)) / (NΣ(x^2) - (Σx)^2) to determine the slope (m).

Step 6: We must apply the formula b = (y - m(x)) / N to determine the y-intercept (b).

Step 7: Using the information provided in the question, we will determine the slope and y-intercept. m = (3* (108+133+120) - (1400+1700+1500)(3)) / (3 (1400+1700+1500)(2)) = 0.09 b = (108+133+120 -0.09*(1400+1700+1500))/3 = 111.33

   Therefore, y = 0.09x + 111.33 is the equation that would most accurately forecast a reasonable property price based on the home's square footage.

A parametric description of the solution set of a linear system is the same as solving the system is the false statement.

If a linear system has at least one solution, only then can the solution set be stated using a parametric description. The set of ordered pairs that make up the solution to an equation with two variables is referred to as the solution set. You'll discover what a solution set is in this tutorial and witness an example. By combining two equations with two variables into one equation with one variable, we can solve a system of equations. Since there are two variables in each equation in the system, replacing a variable with an expression can help minimize the number of variables in an equation.

The percent increase in the cost of the uniform from last year to this year is 25%.

To find the percent increase in the cost of the uniform from last year to this year, we need to calculate the difference between the two prices, divide it by the original price, and then multiply by 100 to express the result as a percentage.

The difference between this year's price and last year's price is:

$65 - $52 = $13

The original price (last year's price) is $52.

So the percent increase in the cost of the uniform is:

percent increase = (difference / original price) x 100

percent increase = ($13 / $52) x 100

percent increase = 0.25 x 100

percent increase = 25%

Therefore, the percent increase in the cost of the uniform from last year to this year is 25%.

Internal validity explains the association between binge-watching tv and irritability.

In the context of a specific study, internal validity refers to how strongly a piece of evidence supports a claim regarding cause and effect. It is one of the most crucial characteristics of scientific research and a crucial idea when considering evidence more generally.

The extent to which alternative explanations for a study's findings (often, sources of systematic error or "bias") can be ruled out is a measure of its internal validity. In contrast, external validity measures how well data support judgments made regarding other situations (that is, the extent to which results can be generalized).

The value of the two required angles of the quadrilateral are:

∠B = 45°

∠A = 135°

Interior consecutive angles of a quadrilateral are supplementary angles, which means that they add up to 180°. This can be proved by the consecutive interior angles theorem which states that "If a transversal intersects two parallel lines, then it means that each pair of interior consecutive angles are supplementary (their sum is 180°).

Now, we are told that the relationship between two consecutive angles of the quadrilateral is:

∠A = 3∠B

Thus, we can say that:

3∠B + ∠B = 180

4∠B = 180

∠B = 45°

Thus;

∠A = 3 * 45° = 135°

Maggie claims that there are transformations that preserve the length of the rectangle's sides. A vertical stretch of scale factor 2 through center C. Option D

Generally, Maggie's claim is that there are transformations that preserve the length of the rectangle's sides.

A reflection over the side RS is a transformation that preserves the length of the rectangle's sides, as the reflection of a segment is congruent to the original segment.

A rotation of 90° clockwise about vertex Q is also a transformation that preserves the length of the rectangle's sides, as a rotation preserves the length of the sides of a polygon.

A dilation of scale factor 1 through center C is also a transformation that preserves the length of the rectangle's sides, as a dilation with a scale factor of 1 leaves the lengths of the sides unchanged.

A vertical stretch of scale factor 2 through center C is NOT a transformation that preserves the length of the rectangle's sides, as a stretch changes the lengths of the sides. Therefore, the answer is D.

Answers:

(a) The ledge can support the plant box. It is safe to put it there.

(b) No the density would not change.

=========================================================

Explanation for part (a)

We'll need the volume of the cube.

volume = side*side*side

volume = 13*13*13

volume = 2,197

Or you could do

volume = (side)^3

volume = (13)^3

volume = 2,197

The volume of the cube is 2,197 cubic cm. Multiply this with the density to determine its weight.

1.33*2197 = 2,922.01

The soil weighs 2,922.01 grams which is below the 2400 gram weight limit. Therefore, the ledge can support the planter.

------------------------------------

Explanation for part (b)

The weight would go down if you only put in half the soil, but the density would not change regardless of how much soil is in there. Why doesn't the density change? Because the density is the amount of stuff per unit volume. The density tells us how packed in a material is. We can scale the amount of material up or down, and retain the same density.

This is based off physics concepts which are bit beyond the scope of this math course, but different materials have different densities. It's common to use a reference table to look up densities of various materials. For instance, ice is less dense than water. This is why ice floats rather than sinks. As another example, gold is more dense than iron. So 1 cubic unit of gold will weigh more compared to 1 cubic unit of iron.

Find the  x-intercept of this equation.

What does this  x-intercept mean?

Use part (b) to comment on the limitations of using equations to model real data.

Solution:

The equation of a straight line is given by y = mx + b; where y and x are variables, m is the slope of the line (rate of change) and b is the y intercept.

Given the equation:

y= -0.025x + 1.25

a) The x intercept is the value of x when y = 0. Therefore:

0 = -0.025x + 1.25

0.025x = 1.25

x = 50

b) The x intercept x = 50 means that the theater admitted 0 number of people in the year 2052 (50 years after 2002).

c) The equation has limitations because from x > 50, we start to see that y is negative; and the number of people admitted cannot be negative.

The probability of getting tails on the coin and an even number on the number cube is 1/4

Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events

The sample space of a coin is:

S = {H, T}

The sample space of a die is:

S = {1, 2, 3, 4, 5, 6}

The above means that:

A coin has 2 faces, one of which is the tail.

So, we have:

P(Tail) = 1/2

A number cube has 6 numbers, 3 or which are even.

So, we have

P(Even) = 3/6

The required probability is

P = P(Tail) * P(Even)

This gives

P = 1/2 * 3/6

To maximize revenue, 350 units must be sold, and the maximum annual revenue is $490,000.

The annual total revenue function is given as R(x) = 28,000x - 4x², where x represents the number of units sold. To find the number of units that must be sold to maximize revenue, we need to determine the maximum point of the revenue function. The maximum point occurs at the vertex of the parabola represented by the revenue function, given that the coefficient of the quadratic term is negative (-4x²). In this case, a = -4 and b = 28,000.

x = -28,000 / (2 * (-4))

x = -28,000 / (-8)

x = 3,500

Therefore, 3,500 units must be sold to maximize revenue. To find the maximum annual revenue, we substitute the value of x = 3,500 into the revenue function,

R(3,500) = 28,000 * 3,500 - 4 * (3,500)²

R(3,500) = 98,000,000 - 4 * 12,250,000

R(3,500) = 49,000,000

Hence, the maximum annual revenue is $49,000,000.

To find the value of V*(s'), The Bellman equation relates the Q*(s, a) values to the state-value function V*(s) by taking the maximum Q-value over all possible actions. Given the Q*(s, a) values and the transition information:

V*(s') = max(Q*(s', a)) for all actions a

In this case, the Q* values for state s are:

Q*(s, \(a_{1}\)) = 10

Q*(s, \(a_{2}\)) = -1

Q*(s, \(a_3}\)) = 0

Q*(s, \(a_{4}\)) = 11

Since s' can be reached from s by taking action a1, we consider the Q* values for state s' and select the maximum value:

V*(s') = max(Q*(s', \(a_{1}\)), Q*(s', \(a_{2}\)), Q*(s', \(a_{3}\)), Q*(s',\(a_{4}\) )

Substituting the given Q* values for s', we have:

V*(s') = max(Q*(s', \(a_{1}\)), Q*(s', \(a_{2}\)), Q*(s', \(a_{3}\)), Q*(s', \(a_{4}\))

         = max(10, -1, 0, 11)
