Answer:

The third side is sqrt(77)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

2^2 + b^2 = 9^2

4+ b^2 = 81

Subtract 4 from each side

b^2 = 81-4

b^2=77

Take the square root of each side

sqrt(b^2) = sqrt(77)

b = sqrt(77)

The third side is sqrt(77)

The function graph denotes the fact that the daily cost associated with making tennis balls is high if they don't make enough balls and then becomes high again if they make too many balls.

We have,

From the graph of the function.

The x-axis denotes the number of tennis balls manufactured.

The y-axis denotes the daily cost of manufacturing the tennis balls.

Now,

From the graph,

The coordinates can be as follows:

(1, 12) to (7, 4)

This shows that the cost decreased as the number of tennis balls manufactured increased.

And,

The coordinates from (7, 4) to (13, 12).

This shows that the cost increases as the number of tennis balls manufactured increases.

Thus,

The function graph denotes the fact that the daily cost associated with making tennis balls is high if they don't make enough balls and then becomes high again if they make too many balls.

Mia is incorrect, as they both ran the same distance, which is the hypotenuse of a right triangle of dimensions 10m and 16m.

The Pythagorean Theorem is a geometry axiom which states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the lengths of the sides squared.

The sides are between the angle of 90º, while the hypotenuse is the segment that connects the sides.

From the image given at the end of the answer, the distances ran from each of them are equal, which is the hypotenuse of a right triangle of dimensions 10 m and 16 m, thus the distance is obtained as follows:

d² = 10² + 16²

d = square root of (10² + 16²)

d = 18.87m.

The problem is given by the image shown at the end of the answer.

Nashville gets 13.8 units of rainfall less than Miami.

We have to give that,

The annual rainfall in Albany is 0.33 inches less than the annual rainfall in Nashville.

Here, Miami's rainfall is 61.05 inches

Albany's rainfall is 46.92 inches.

Let the rainfall in Nashville be x units.

So, rainfall in Albany is,

x - 0.33

Now Albany gets 46.92 units of rainfall.

So, Nashville gets,

46.92 = x - 0.33

x = 46.92 + 0.33

x = 47.25 units

And Miami gets 61.05 units of rainfall.

So, Nashville gets,

61.05 - 47.25

= 13.8 units

Hence, Nashville gets 13.8 units of rainfall less than Miami.

Answer:

An equation in the form y = mx + b is in the 'slope y-intercept' form where m is the slope and b is the y-intercept. We can rewrite our equation, y = 4, in slope y-intercept form as follows: y = 0x + 4. Here, it is clear that the slope, or m, is zero. Therefore, the slope of the horizontal line y = 4 is zero

The term utilized to make inferences about certain population parameters is a) samples.

In statistical analysis, samples are a subset of a larger population that are selected for observation and analysis. By studying the sample, statisticians can make inferences about the larger population from which it was drawn. This allows for predictions to be made about the entire population, based on information gathered from a smaller subset.

Equations and metrics are important in statistical analysis, but they are not used to make inferences about population parameters. Equations are used to model relationships between variables and to test hypotheses, while metrics are used to quantify the properties of data sets.

Statistics, on the other hand, is the branch of mathematics that deals with the collection, analysis, interpretation, presentation, and organization of data. Statistics is used to make sense of data and to draw conclusions about the larger population from which the sample was drawn.

In summary, samples are an important tool for statisticians to make inferences about certain population parameters, and statistics is the field that studies these methods of data analysis.

Therefore, the correct answer is a) samples.

The SSS Similarity Theorem states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are similar. This theorem is also known as the Side-Side-Side Similarity Theorem or the SSS Similarity Postulate.

What is the similarity theorem of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle similarity is indicated here by the symbol (~).

SSS or Side-Side-Side Similarity.
If all three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.
Thus, if AB/XY = BC/YZ = AC/XZ then ΔABC ~ΔXYZ.
From this result, we can conclude that-
∠A = ∠X, ∠B = ∠Y and ∠C = ∠Z
Hence, we have described the SSS similarity theorem.

Answer:

The exact values of sinθ = -7/√58.

The exact value of  secθ = -√58/3 and

The exact value of tanθ = 7/3

Step-by-step explanation:

Given that a point on the terminal side is of an angle is (x,y) and we are given (-3, -7). So x = -3 and y = -7. The length of its terminal side is given by r = √(x² + y²) = √((-3)² + (-7)²) = √(9 + 49) = √58

We know that sinθ = y/r.

So, sinθ = y/r = -7/√58

We know that secθ = 1/cosθ = 1/x/r = r/x

So, secθ = r/x = √58/-3 = -√58/3

We know that tanθ = y/x.

So, tanθ = y/x = -7/-3 = 7/3

So, the exact values of sinθ = -7/√58.

The exact value of  secθ = -√58/3 and

The exact value of tanθ = 7/3

Systematic risk is the type of risk for which you can be rewarded with a higher expected return.

So, the correct answer is A

Systematic risk, also known as market risk or non-diversifiable risk, affects the entire market and cannot be eliminated through diversification.

Investors are compensated for taking on systematic risk through higher expected returns as they bear the fluctuations and uncertainties associated with the overall market.

In contrast, firm-specific, diversifiable, and idiosyncratic risks are specific to individual companies or industries and can be mitigated through diversification in an investment portfolio, so investors don't get rewarded with higher expected returns for these types of risks

Hence, the answer of the question is A.

After about 1.5 hours, David and Amy will be exactly 23 miles apart.

When we're talking about two people or objects moving in different directions, we should use the Pythagorean Theorem to solve problems like this.

When we apply the theorem to this problem,

we get the following equation:

a² + b² = c²

where,

a = 17t,

b = 15t and

c = 23

We can substitute these values into the equation and solve for t:

a² + b² = c²(17t)² + (15t)²

= 23²t² 289t² + 225t²

= 529t² 514t²

= 529t² - 514t²

t² = 23² / (529 - 514)

t² = 23 / 15t = √(23 / 15)

t ≈ 1.5

Therefore, after about 1.5 hours, David and Amy will be exactly 23 miles apart.

The statement that correctly reflects the traditional usage of significance level in statistical research is quality control and political polling uses a 1% significance level, while consumer research uses a 5% significance.

In statistical research, the significance level is a threshold that is used to determine whether the results of a study are statistically significant. It represents the probability of rejecting the null hypothesis when it is actually true.

The significance level is typically set before conducting a study, and its value depends on the specific application and context of the research.

The most commonly used significance levels in different fields of research can vary, depending on the goals of the study and the consequences of making Type I and Type II errors.
