Answer: Scatter Plot 2

Step-by-step explanation: Usually with graphs like this, anything relative to time (age) will be on the x axis because the text messages depends on the age. This immediately knocks out number 1. Then you just have to start graphing points on the scatter plot and whichever one lines up best, which happens to be #2, is the correct answer.

Hope this helps.

Step-by-step explanation:

5% of 2.4 million is 120,00

Let x represent the age of a person.

From the information given, a person must be at least 2 years old. This means that the person must be greater than or equal to 2 years. The inequality symbold representing greater than or equal to is '≥'

Thus, the inequality is

x ≥ 2

The graph would be a vertical line passing through x = 2 and the shaded area would be to the right of the line. The line would be solid, indicating that the points on the line are inclusive. Thus, the correct graph is

The best reason to prefer the least-squares regression line that uses x to predict log(y) would be that the standard deviation of the residuals is smaller.

When we have a scatterplot that shows a positive, nonlinear association, we may attempt to transform the data to linearize the association.

In this case, two different transformations were attempted, using the logarithm of the y values and using the square root of the y values.

Two least-squares regression lines were then calculated, one that uses x to predict log(y) and the other that uses x to predict Vy.
To determine which of these regression lines is preferred, we need to consider several factors.

One important factor is the value of r2, which tells us how much of the variability in the response variable (y) is explained by the regression model.

A larger r2 indicates a better fit to the data.
However, in this case, the value of r2 alone may not be sufficient to determine which regression line is preferred.

Another important factor to consider is the standard deviation of the residuals, which measures how much the actual values of y deviate from the predicted values. A smaller standard deviation of the residuals indicates a better fit to the data.

Furthermore, we should also consider the slope of the regression line, which tells us the direction and strength of the relationship between x and y.

A greater slope indicates a stronger relationship.
In addition, we need to examine the residual plot, which shows the difference between the actual values of y and the predicted values.

A residual plot with more random scatter indicates a better fit to the data.

Finally, we should also consider the distribution of residuals, which should be approximately Normal. A more Normal distribution of residuals indicates a better fit to the data.

If many random samples of this size were taken and intervals constructed, 90% of them would contain the true population mean. In repeated sampling, about 90% of the constructed confidence intervals will capture the true population mean difference. The correct answer is C.

When we construct a confidence interval, it is important to understand its interpretation. In this case, the correct answer (Oc) states that if we were to take many random samples of the same size and construct confidence intervals for each sample, approximately 90% of these intervals would contain the true population mean difference.

This interpretation is based on the concept of sampling variability. Due to random sampling, different samples from the same population will yield slightly different sample means.

The confidence interval accounts for this variability by providing a range of values within which we can reasonably expect the true population mean difference to fall a certain percentage of the time.

In the given scenario, when constructing a 90% confidence interval for the paired difference, it means that 90% of the intervals we construct from repeated samples will successfully capture the true population mean difference, while 10% of the intervals may not contain the true value.

It's important to note that this interpretation does not imply a probability or chance for an individual interval to capture the true population mean. Once the interval is constructed, it either does or does not contain the true value. The confidence level refers to the long-term behavior of the intervals when repeated sampling is considered.

If the perimeter of the isosceles triangle is 12 cm, then the base of the triangle (x), as well as the length of the triangle leg (x) is 4 cm.

An isosceles triangle is a type of triangle in which two sides have the same length. These two equal sides are referred to as the legs of the triangle, while the remaining side is known as the base.

The perimeter of a triangle is the sum of the lengths of all its sides. In this case, since the triangle is isosceles, the base and one leg have the same length (x), and the other leg also has the same length (x). Therefore, the perimeter of the triangle is 2x + x = 3x. Given that the perimeter of the isosceles triangle is 12 cm, then:

3x = 12

 x = 12/3

 x = 4

So, the base and legs of the isosceles triangle each have a length of 4 cm.

Two additional polar representations of the point with coordinates (-4, 3π/2) within the interval [-2π, 2π] are (-4, 7π/2) and (4, 5π/2).

You find two additional polar representations of the point with polar coordinates (-4, 3π/2), keeping the angle in the interval [-2π, 2π].
First, let's understand that there can be multiple representations of a point in polar coordinates by adding or subtracting multiples of 2π to the angle while keeping the radius the same or by negating the radius and adding or subtracting odd multiples of π to the angle.
Representation 1:
Keep the radius the same and add 2π to the angle:
(-4, 3π/2 + 2π) = (-4, 3π/2 + 4π/2) = (-4, 7π/2)
Representation 2:
Negate the radius and add π to the angle:
(4, 3π/2 + π) = (4, 3π/2 + 2π/2) = (4, 5π/2)
So, two additional polar representations of the point with coordinates (-4, 3π/2) within the interval [-2π, 2π] are (-4, 7π/2) and (4, 5π/2).

Given:

A student says that the graph of the equation \(y = 3(x + 8)\) is the same as the graph of \(y = 3x\), only translated upwards by 8 units.

To find:

Whether the student is correct or not.

Solution:

Initial equation is

\(y=3x\)

\(f(x)=3x\)

Equation of after transformation is

\(y=3(x+8)\)

\(g(x)=3(x+8)\)

Now,

\(g(x)=f(x+8)\)      ...(i)

The translation is defined as

\(g(x)=f(x+a)+b\)        ...(ii)

Where, a is horizontal shift and b is vertical shift.

If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.

If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.

From (i) and (ii), we get

\(a=8\text{ and }b=0\)

Therefore, the graph of \(y=3x\) translated left by 8 units. Hence, the student is wrong.

A mathematical expression is neither true nor false; it is evaluated rather than being assigned a truth value.

A mathematical expression, by itself, is not considered true or false because it does not make a specific claim or statement. An expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, and division. It represents a computation or evaluation, but it does not assert any truth value.

For example, the expression "2 + 3" is simply a calculation that evaluates to the value 5. It does not make a claim or statement that can be determined as true or false. Similarly, expressions like "\(x^2 + 4\)" or "sin(θ) + cos(θ)" represent mathematical computations but do not have a truth value.

To determine the truth value of a mathematical statement, you need an equation or inequality that makes a specific claim or relationship between mathematical expressions. For instance, the equation "2 + 3 = 5" is a mathematical statement that can be determined as true, while the inequality "x > 5" depends on the value of x and can be evaluated as true or false.

The information that Raj could have used to determine that ray LH is the bisector of ∠GLI is m∠GLI = 2m∠GLH. The correct answer is option C.

Consider the given figure.

The angle bisector theorem states that if a ray (like LH) bisects an angle, it divides the opposite side (GLI) into segments that are proportional to the adjacent sides (GLH and HLI) of the angle.

One can deduce that if m∠GLI is twice the measure of m∠GLH, then LH is an angle bisector of ∠GLI.

The statement "m∠GLI = 2m∠GLH" indicates that the angle GLI is twice the measure of the angle GLH. This suggests that the angle GLI is divided into two equal parts, with LH being the bisector of ∠GLI.

Therefore, the correct answer is option C.

(-1, -1)

(1,3)

Step-by-step explanation:

Given the function;

y = 2x + 1

when x = 0

y = 2(0)+1

y = 1

Hence the required pair is (0, 1)

when x = -1

y = 2(-1) + 1

y = -2 + 1

y = -1

Hence the coordinate is (-1, -1)

when x = 1

y = 2(1) + 1

y = 2 + 1

y =3

Hence the coordinate is (1, 3)

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan30° = \(\frac{1}{\sqrt{3} }\) , then

tan30° = \(\frac{opposite}{adjacent}\) = \(\frac{y}{4\sqrt{3} }\) = \(\frac{1}{\sqrt{3} }\) ( cross-  multiply )

y × \(\sqrt{3}\) = 4\(\sqrt{3}\) ( divide both sides by \(\sqrt{3}\) )

y = 4

Answer:

y=4

Step-by-step explanation:

If we have a triangle with angles A, B, and C. The law of sines says that the proportion between the sin of angle A and its opposite side is equal to the proportion between the sin of angle B and its opposite side and it is equal to the proportion between the sin of angle C and its opposite side.

So, by the law of sines we can say that:

\(\frac{sen(60)}{4\sqrt{3} } =\frac{sen(30)}{y}\)

Solving for y, we get:

\(sin(60)*y=4\sqrt{3}*sin(30)\\\frac{\sqrt{3} }{2}y=4\sqrt{3}*0.5\\ \frac{1}{2} y=4*0.5\\y = 4\)
