Alisha needs to use a fraction of 3/8 of each of the ingredients on the recipe.
How we need to adjust the recipe?We know that a pancake recipe calls for 8 eggs and some other ingredients.
But Alisha only has 3 eggs, so she needs to adjust the recipe.
The fraction of each one of the other ingredients that she needs to use is equal to the fraction between the number of eggs that she has and the number of eggs that the recipe calls, it is:
N = 3/8
So she needs to use 3/8 of each of the ingredients that the recipe calls.

What is the deadweight losscaused by the subsidy?
A.$100
B.$200
C.$3,200
D.$800
The deadweight loss caused by a subsidy is the amount of economic welfare that is lost because of the subsidy. In this example, the deadweight loss caused by the subsidy is $800. Therefore, correct option will be D.$800.
This occurs because the subsidy distorts the market by creating a price below the market equilibrium. This results in an inefficient distribution of resources as some consumers are willing to pay a higher price than the subsidized price.
Additionally, it creates an excess demand for the good, resulting in an over-allocation of resources. In this case, the deadweight loss is the difference between the market price and the subsidized price, which is $800. The deadweight loss is a negative externality of subsidies, as it reduces the overall efficiency of the market.

5x - 30 = 3x
5x - 3x = 30
2x = 30
x = 30/2
x = 15.
For triangle ABD, we would apply the basic proportionality theorem as follows:

How do you redefine a removable discontinuity to make it continuous?
Although certain functions have discontinuities, it is feasible to redefine the function so that it becomes continuous at that point.
A continuous function in mathematics is a function without discontinuities, or any sudden changes in value. If we can guarantee arbitrarily small changes in the input of a function by limiting small enough changes, then the function is continuous.
We only need to change the function's value at this point to make f(x) continuous at x=0. To satisfy the concept of continuous functions and resolve the example issue, make the necessary adjustment to make the one-sided limits equal. We therefore set f(0)=4 f(0) = 4

The width of the fountain will be 3 feet and the fraction of the area of the courtyard will be occupied by the fountain is 3/44
What is the area?Is the measure of the space occupied by a body bounded by an environment called perimeter, the same is expressed in units of squared side. Example: ft^2, m^2
The formula and procedure to solve this geometry exercise is:
A(rectangle) = length * width
Information about the problem:
A(stone) = 246 ft^2
A(fountain) = ?
Width = ?
Calculating the area of the fountain we get:

For positive acute angles A and B, it is known that sin A= 4/5 and tan B= 45/28 . Find the value of IIT A+B in simplest form. Question. user avatar image ...
the solution of sin(A + B) in simplest form is 27/35.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We use the trigonometric identity as;
sin(A + B) = sin A cos B + cos A sin B
Hence, we need to find cos A and cos B.
Here, We know that;
⇒ sin A = 4/5,
By use the Pythagorean identity;
sin²A + cos² A = 1
sin² A + cos² A = 1
(4/5)² + cos² A = 1
16/25 + cos² A = 1
cos² A = 9/25
cos A = 3/5
And, we can use the identity;
tan B = sin B / cos B
to find sin B:
tan B = sin B / cos B
45/28 = sin B / √(1 - sin² B)
(45/28)² = sin² B / (1 - sin² B)
sin² B + (45/28)² sin² B = (45/28)²
sin² B (1 + (45/28)²) = (45/28)²
⇒ sin B = 3/7
Now that we have sin A, cos A, sin B, and cos B,
We can put them into the formula for sin(A + B):
sin(A + B) = sin A cos B + cos A sin B
sin(A + B) = (4/5)(45/28) + (3/5)(3/7)
sin(A + B) = 27/35
Therefore, the solution of sin(A + B) in simplest form is 27/35.

y=x+30
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equations are y=4x+9 and y=x+30
Let us subtract both the equations
y-y=4x+9-x-30
0=3x-21
Add 21 on both sides
21=3x
Divide both sides by 3
x=7
Now let us plug in value of x in any of the equation to get y.
y=4(7)+9
=28+9
y=37
Hence, value of x is 7 and value of y is 37 for the equations y=4x+9
y=x+30

you have been hired by an industrial company to lead a project to help improve their custom safety training course. the course is intended to prepare the candidates for a globally recognized certification. to help rate the effectiveness of the course, you create a scatter diagram and compare the hours of preparation (x-axis) with the final score (y-axis) of previous employees. from the diagram, it is determined that there is a negative linear correlation. which conclusion can be made using the data from this chart? answers a. the more time that was used to prepare, the lower the score b. the data is inconclusive; statistical sampling should be used instead c. the amount of preparation time does not directly affect the candidate's score d. the more time that was used to prepare, the higher the score
The conclusion can be made using the data in option A the negative linear correlation means that as the preparation time increases, the final score decreases in a linear pattern.
The conclusion that can be made from the data in the scatter diagram is that the more time that was used to prepare, the lower the score (answer A). The negative linear correlation means that as the preparation time increases, the final score decreases in a linear pattern. This suggests that there may be a relationship between the amount of preparation time and the final score, but further investigation and statistical analysis is needed to confirm this relationship.
Linear correlation refers to the relationship between two variables that can be represented by a straight line on a scatter plot. The relationship between the two variables can be positive, negative, or neutral. Positive linear correlation means that as one variable increases, the other variable also increases in a linear pattern. Negative linear correlation means that as one variable increases, the other variable decreases in a linear pattern. A neutral linear correlation means that there is no relationship between the two variables.
