Answer:

3

Step-by-step explanation:

3 because you have to find x, you have to find x and y and then the overall answer

The given system of equations,

y = 1/4 x + 1

y = 1/4 x - 1

has no solution.

Given a system of equations.

There are two equations in the system.

We have to find the number of solutions for the system if it exists.

Consider the equations,

y = 1/4 x + 1

y = 1/4 x - 1

Since both the equations are in y value, they are equal.

1/4 x + 1 = 1/4 x - 1

1/4 x - 1/4 x = -1 - 1

0 = -2

This is not possible.

This means that the given system has no solution.

Hence the given system of equations has no solution.

What is sinusoidal wave?

A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.

Let the graphs of y = sin(x) and y =sin(2x) are given.

From this graphs we have to find the value of c and d.

First from y = sin(x) to find the value of 'a'.

consider the point [tex](a, -\frac{4}{5})[/tex]

⇒

[tex]sin(a) = -\frac{4}{5} \\a = sin^-^1(-\frac{4}{5})\\ a = -53.13[/tex]

Now to find the value of 'c'.

Plug   a = -53.13  in y = sin(2x)

[tex]sin(2a) = c\\sin(2(-53.13)) = 0.52622\\sin2a= 0.53[/tex]

Hence, the value of 'c' is c = 0.53.

Now to find the value of d.

First y = sin(x) to find the value of b.

Consider, the point [tex](b, \frac{5}{13})[/tex]

⇒

[tex]sinb = \frac{5}{13} \\b = sin^-^1(\frac{5}{13})\\ b = 22.62[/tex]

Now to find value of d.

Plug b = 22.62 in y = sin(2x)

[tex]sin(2b) = d\\sin(2(22.62)) = 0.95138\\sin(2b) = 0.95[/tex]

So, the value of 'd' is 'd = 0.95'.

Hence, from the given graphs the values of c and d are, c = 0.53,

d = 0.95.

Answer:

4 liters

Step-by-step explanation:

We need to first figure out what the proportional value is.

(Y ×? = X)

10(Y) × 2.5 = 25 (X)

If the capacity of X is equivalent to 10 liters, then we need to use the same proportional value to get the number of liters for Y.

10 ÷ 2.5 = 4

Trough Y can contain 4 liters

The t-test is appropriate because it can handle small sample sizes and is robust to violations of normality assumptions.

Mathematical statistical tests are techniques for data analysis and drawing conclusions about a population from a sample. These tests employ mathematical formulae and probability theory to assess if a participant's result is statistically significant, implying that it is unlikely to have happened by chance. Comparing two or more groups, figuring out how variables relate to one another, and assessing the accuracy and validity of data may all be done using statistical tests. They are frequently used to derive inferences from experimental or observational data in disciplines including psychology, economics, and sociology.The outcomes of these tests are used to determine whether to accept or reject a hypothesis and can offer important insights into the underlying patterns and relationships in data.

An equation that plots the total cost, y, of renting the scooter against the duration, x is  y=7.50x+45

3x - 5 = 16 is an illustration of an equation. By solving for x, we discover that the variable's value is 7, or x = 7. By deleting parenthesis and merging related terms, you can simplify either side of an equation and obtain the solution. Together with the variables for which the equation must be solved, the values of the variables that must satisfy the equality to compose the answer are referred to as the unknowns. Equations can be categorized as identities or conditional equations. An identity holds true regardless of the value given to the variables. A conditional equation's variables can only have specific values that produce the truth.

Line of reflection for the image vertices are A'(5, 1), B'(3, –1), and C'(7, –1) will be x = 2..

What is mean by Reflection?
Reflection is the process of taking the time to think deeply about the experiences, events, and choices that shape our lives. Reflection allows us to consider how our views and opinions have changed over time, and to take stock of our successes and failures. Reflection can also help us understand our personal values and beliefs and how we can use them to make more informed decisions in the future. Reflection involves looking inward and assessing our thoughts and feelings, as well as looking outward and considering our interactions with the world around us. Taking time for reflection can help us gain insight into our behaviors and motivations, as well as identify areas of our lives that need improvement. It can also help us stay mindful of our goals and stay on the path to achieving them. Reflection is an important part of personal growth and development, and can be a valuable tool for gaining self-awareness and increasing our emotional intelligence.

Given that;
After a reflection of the figure,
The image vertices are A'(5, 1), B'(3, –1), and C'(7, –1).
And, In the figure;
The vertices are A(-1, 1), B'(1, –1), and C'(-3, –1).

We need to find how many gallons of 80%

8x, since we don't know how many gallons

mixed with 250 gall of 40%: 0.40(250)

and we want a mix at 70%. The mix will include the 0.8x and the 0.4(250) Like this:

8x+0.4(250)=0.7x+0.7*250

Multiply on both sides of the equation

0.8x+100= 0.7x+175 Subtract 100 on both sides

0.8x= 0.7x+75

Subtract 0.7 on both sides

0.1x= 75

The inequalities that represent the line in the graph will be y < x - 3 and y = -(2/3)x. Then the correct option is B.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

From the graph, the blue line has a slope of 1 and the y-intercept is at (0, -3), then the inequality is calculated as,

y < x - 3

The red line is passing through the origin and (3, -2), then the equation is given as,

y - 0 = [(-2 - 0) / (3 - 0)](x - 0)

y = -(2/3)x

The disparities that address the line in the chart will be y < x - 3 and y = - (2/3)x. Then the right choice is B.

We can conclude that the width of the rectangular ground is 19ft.

A quadrilateral with all of its angles equal, or right angles, is a rectangle.

In addition to having all equal angles, a square also has all equal sides. Therefore, a special case of a square is a rectangle.

To put it another way, a rectangle can also be a square.

So, we know that:

The perimeter of the rectangular ground is 90ft.

The length of the rectangular ground is 26ft.

Now, the width will be:

Perimeter of rectangle formula: P =  2(l+w)

Now, put the values and substitute as follows:

P =  2(l+w)

90 =  2(26+w)

90 = 52 + 2w

2w = 90 - 52

2w = 38

w = 38/2

w = 19ft

As given in the question,

Side length of the given rhombus 's' = 51 units

Length of the shorter diagonal of given rhombus 'a' = 48 units

Let us consider length of the longer diagonal of the given rhombus be 'b'

As per the property of the rhombus:

Diagonals of the rhombus bisects each other at right angle

Triangle formed by side length bisecting diagonals is right angled triangle.

Using Pythagoras theorem we have,

(Side length)² = (a/2)² + (b/2)²

Substitute the values

⇒ (51)² = (48/2)² + (b/2)²

⇒2601 = 576 + (b/2)²

⇒(b/2)² = 2601 -576

⇒(b/2)² = 2025
