Step-by-step explanation:

A linear pair sum to 180° , then

x - 30 + x + 76 = 180 , that is

2x + 46 = 180 ( subtract 46 from both sides )

2x = 134 ( divide both sides by 2 )

x = 67

Then

∠ 1 = x - 30 = 67 - 30 = 37°

∠ 2 = x + 76 = 67 + 76 = 143°

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

(11)

Since T is the midpoint of SU , then

ST = TU , that is

5x = 3x + 32 ( subtract 3x from both sides )

2x = 32 ( divide both sides by 2 )

x = 16

Then

ST = 5x = 5(16) = 80

TU = 3x + 32 = 3(16) + 32 = 48 + 32 = 80

SU = 5x + 3x + 32 = 8x + 32 = 8(16) + 32 = 128 + 32 = 160

a) The line of best fit is y = 10x  + 60

b) the grade for a student that did not study at all is 0.

What is the slope?

The slope of a line represents the change in the dependent variable (y) for a unit change in the independent variable (x). In this case, the slope of the line of best fit represents the average change in the test grade for a one hour increase in studying. To find the slope, you can use the formula:

m = (Σxy - (Σx)(Σy)/n) / (Σx² - (Σx)²/n)

a) The line of best fit is a line that best approximates the relationship between two variables. To find the line of best fit for this data, we can use the least squares method to minimize the sum of the squares of the differences between the observed data points and the line. The equation of the line of best fit is y = mx + b, where m is the slope and b is the y-intercept. The slope can be calculated as (Σxy - (Σx)(Σy)/n) / (Σx² - (Σx)²/n), and the y-intercept as (Σy - m(Σx)) / n, where n is the number of data points.

(2, 60) and (5, 90)

The slope is

y2 - y1 =  m(x2 - x1)

90 - 60 = m(5-2)

30 = 3m

m = 10

Slope line is

y - 60 = m(x - 2)

y = 10x - 20 + 80

y = 10x  + 60

b) To estimate the grade for a student that did not study at all, we can use the line of best fit and plug in x=0 for the number of hours studying. The estimated grade for a student that did not study at all would be the y-intercept of the line,

which represents the expected test grade when

x = 0

Answer:

The polynomial is x^3-x^2-33x+63

Step-by-step explanation:

Here, we want to find a polynomial of degree 3 with the given roots

-7 with a multiplicity of 1 and 3 with a multiplicity of 2

if x = -7

x + 7 is a root

if x = 3

x -3 is a root

Since the multiplicity of this is 2, we have x-3 twice

The complete polynomial is;

(x-3)(x-3)(x+7)

= x^2-6x+9(x + 7)

= x(x^2-6x+9) + 7(x^2-6x+9)

Step-by-step explanation:

3 x 2.5 = 7.5

Given data:

The first equation is 2x+3y=-12.

The second equation is x+y=9.

The second equation can be written as,

y=9-x

Substitute the above value in second equation.

2x+3(9-x)=-12

2x+27-3x=-12

-x=-39

x=39

The value of y is,

39+y=9

y=-30.

Thus, the value of x is 39, and the value of y is -30.

If he spins the four-part spinner 100 times, he can expect to win each prize approximately 25 times. This can be determined by using the concept of probability.

Let's say Gustavo spins the spinner 100 times to demonstrate the likelihood of winning each prize. Since the spinner has four equal parts representing the four prizes, each prize has a 1/4 (or 25%) chance of being won on any given spin.

After spinning the spinner 100 times, we can expect Gustavo to win each prize approximately 25 times. However, it's important to note that these are expected values based on probability, and the actual results may vary due to chance.

Here's a breakdown of the expected number of times Gustavo might win each prize:

1. Video game system: Gustavo can expect to win the video game system around 25 times out of the 100 spins.

2. Bicycle: Similarly, Gustavo can expect to win the bicycle approximately 25 times out of the 100 spins.

3. Watch: Gustavo can also expect to win the watch around 25 times out of the 100 spins.

4. Gift card: Lastly, Gustavo can expect to win the gift card approximately 25 times out of the 100 spins.

Keep in mind that these are average values based on the assumption that each prize has an equal chance of being won. In reality, due to random chance, the actual results might deviate slightly from these expected values.

Answer:

f(6) = g(3)

Step-by-step explanation:

Which statement is true regarding the functions on the graph?

f(6) = g(3)

f(3) = g(3)

f(3) = g(6)

f(6) = g(6)

Solution:

g(x) passes through the points (-3, 0) and the y-axis at (0, 3). The equation of g(x) is given as:

g(x) = y

\(y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\)

\(y-0=\frac{3-0}{0-(-3)}(x-(-3))\\\\y=x+3\\\\g(x)=y= x+3\\\\g(x)=x+3\)

f(x) passes through the points (0, -3) and the y-axis at (1, 0). The equation of f(x) is given as:

f(x) = y

\(y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\)

\(y-(-3)=\frac{0-(-3)}{1-0}(x-0))\\\\y+3=x\\\\f(x)=y= x-3\\\\f(x)=x-3\)

f(6) = x-3 = 6 - 3 = 3

g(3) = x + 3 = 3 + 3 = 3

f(6) = g(3)

The given inequality is:

To graph it, first, let's find the equation of the line in slope-intercept form:

The slope is 4 and the y-intercept is -1.

So, starting at y=-1 and x=0, we move 4 units up and 1 unit to the right to find the next point on the graph.

It will be located at (1,3).

By joining these two points, we can graph the line of the inequality:

The property illustrated in Step 4 is the "associative property of addition". which is the correct answer would be an option (A).

The associative property of addition is a rule which states that when adding three or more numbers, we can arrange them in any configuration, and the resultant sum is unaffected by how they are arranged.

(a + b) + c = a + (b + c)

The property illustrated in Step 4 is the "associative property of addition". This property states that the order in which we add numbers does not affect the result of the addition.

In Step 4, we use the associative property to rearrange the terms in the expression so that we can more easily apply the distributive property in the next step.

If a point (x , y) divides a line in the ratio of m : n, where the two endpoints of the line are (x1, y1) and (x2, y2), then-

x = (nx1 + mx2)/ (m + n)

and y = (ny1 + my2)/ (m + n)

Here, M (4,6) is the midpoint of AB and B is (5,7)

Let the coordinates of A be (x2, y2)

Therefore,

The x-intercepts of the function h(x) = x^2 - ax are x = 0 and x = a,The y-intercept of the function h(x) is y = 0.These results can be justified by the algebraic steps taken to find the x and y intercepts.

To construct a product of two functions with one x-intercept, we can consider the following:

Let's start with two functions:

f(x) = x

g(x) = (x - a), where 'a' is a constant representing the x-coordinate of the x-intercept.

The product of these two functions is given by:

h(x) = f(x) × g(x)

= x × (x - a)

= x^2 - ax

To find the x-intercept of the function, we set h(x) equal to zero and solve for x:

x^2 - ax = 0

Factoring out an 'x' from the equation:

x(x - a) = 0

Now, we have two possibilities for the x-intercept:

   x = 0

   x - a = 0, which gives x = a

Therefore, the function h(x) has two x-intercepts: x = 0 and x = a.

To find the y-intercept, we set x = 0 in the function h(x):

h(0) = 0^2 - a(0)

= 0

Hence, the y-intercept of the function h(x) is y = 0.

In summary:

   The x-intercepts of the function h(x) = x^2 - ax are x = 0 and x = a.

   The y-intercept of the function h(x) is y = 0.

These results can be justified by the algebraic steps taken to find the x and y intercepts.

To find the indirect utility function, we need to solve the utility maximization problem subject to the budget constraint and express the maximum utility achieved as a function of the prices and income.

Given the utility function U = max(X, Y) and the budget constraint P₁X + P₂Y = M, we can solve for X and Y in terms of prices (P₁, P₂) and income (M).

First, let's consider the different cases:

If P₁ ≤ P₂:

In this case, the individual would choose to consume only good X. Therefore, X = M / P₁ and Y = 0.

If P₂ < P₁:

In this case, the individual would choose to consume only good Y. Therefore, X = 0 and Y = M / P₂.

Now, we can express the indirect utility function in terms of the prices (P₁, P₂) and income (M) for each case:

a) If P₁ ≤ P₂:

In this case, the individual maximizes utility by consuming only good X.

Therefore, the indirect utility function is V(P₁, P₂, M) = U(X, Y) = U(M / P₁, 0) = M / P₁.

b) If P₂ < P₁:

In this case, the individual maximizes utility by consuming only good Y.

Therefore, the indirect utility function is V(P₁, P₂, M) = U(X, Y) = U(0, M / P₂) = M / P₂.

c) and d) do not match any of the cases above.

Therefore, among the given options, the correct answer is:

a) M / max(P₁, P₂).

The concept that a message gives different meanings to different objects is called option (b) polymorphism.

Polymorphism is a fundamental concept in object-oriented programming (OOP) that allows different objects to respond to the same message or method invocation in different ways. In other words, it allows objects of different classes to be treated as if they were of the same class, as long as they implement the same method or message.

This can make code more flexible, reusable, and easier to maintain. Polymorphism is achieved through inheritance, interfaces, or overloading methods. For example, a "draw" method could be implemented differently for different shapes, such as circles, rectangles, or triangles.

The critical t-value that corresponds to a 50% confidence level with 23 degrees of freedom is approximately 0.685.

To find the critical t-value that corresponds to a 50% confidence level, we need to use the t-distribution table or a statistical calculator. The t-distribution is a probability distribution that is used for hypothesis testing and constructing confidence intervals when the sample size is small or when the population standard deviation is unknown.

In this case, we are given 23 degrees of freedom. Degrees of freedom (df) represent the number of independent observations in a sample. For a t-distribution, the degrees of freedom are typically equal to the sample size minus 1.

To find the critical t-value, we need to determine the desired confidence level and the two-tailed probability associated with it. Since the confidence level is given as 50%, we divide it by 2 to obtain the two-tailed probability.

The two-tailed probability for a 50% confidence level is 0.50 / 2 = 0.25.

Now, using the t-distribution table or a statistical calculator, we can find the critical t-value that corresponds to a two-tailed probability of 0.25 and 23 degrees of freedom.

Looking up the t-distribution table with 23 degrees of freedom and a two-tailed probability of 0.25, we find that the critical t-value is approximately 0.685.

Therefore, the critical t-value that corresponds to a 50% confidence level with 23 degrees of freedom is approximately 0.685.

It's important to note that a 50% confidence level is not commonly used in statistical analysis. Confidence levels are typically chosen to be 90%, 95%, or 99% to provide a higher level of confidence in the results. A 50% confidence level implies a high level of uncertainty and is not widely used in practice.
