The collection, description, analysis, and drawing of conclusions from quantitative data are all included in the area of statistics, which is a branch of applied mathematics. Probability theory, linear algebra, and calculus of differential and integrals are some of the core mathematical concepts in statistics.

Descriptive statistics were used in the statement.

Descriptive statistics is a branch of statistics that deals with the collection, presentation, and summary of data. It is used to describe and summarize the main features of a data set, such as measures of central tendency (e.g., mean, median, mode) and measures of dispersion (e.g., range, variance, standard deviation).

In this case, the statement is simply reporting a single value, the average credit card debt for college students in 2008. This is an example of a descriptive statistic because it is a summary measure that describes a characteristic of the population or sample under study.

Answer:

The calculated value Z = 1.39 <1.96 at 0.05 level of significance

The null hypothesis is accepted

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 43

Given that the mean of the sample = 47

Given that the standard deviation of the Population = 25

Given that the sample size 'n' = 76

Step(ii):-

Null hypothesis:H₀: μ = 43

Alternative Hypothesis: H₁: μ ≠ 43

Test statistic

           \(Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }\)

          \(Z = \frac{47-43 }{\frac{25}{\sqrt{76} } }\)

          Z = 1.39

Level of significance = 0.05

The critical value = 1.96

This expression 40=4+(n-1)3 represents the correct arithmetic progression.

What is an arithmetic progression?

Every term following the first is derived by adding a constant value, known as the common difference, in an arithmetic progression.

We have,

4 + 7 + 10 + 13 + 16 + 19 + 22 + 25 + 28 +31 + 34 + 37 + 40

Arithmetic progression formula:

                             \(a_{n}=a_{1}+(n-1)d\)

where

\(a_{n}\) = the nᵗʰ term in the sequence

\(a_{1}\) = the first term in the sequence

\(d\) = the common difference between terms

By using arithmetic progression formula we can find last term of an Arithmetic series.

                    \(a_{n}=a_{1}+(n-1)d\)

                    \(a_{n}\)= 4 + (n-1)3

                    \(a_{n}\) = 4 + (13-1)3

                     \(a_{n}\)  = 40.

we have calculated the last term by using arithmetic progression formula which is 40.

Hence, This expression 40=4+(n-1)3 represents the correct arithmetic progression.

Answer: slope = 3

y - intercept = -2

Equation = y = 3x - 2

According to the graph, the points are (2, 4) and (0, -2)

Points: (2, 4) and (0, -2)

Firstly, we need to find the slope of the graph

Slope = rise / run

rise = y2 - y1

run = x2 - x1

The standard form of slope intercept form of equation is given as y = mx + b

(y - y1) = m (x - x1)

where m = slope, and b = intercept

y1 = 4 and x1 = 2

(y - 4) = 3(x - 2)

Open the parentheses

y - 4 = 3x - 6

isolate y

y = 3x - 6 + 4

y = 3x - 2

Answer:

The length of the rectangle = 6 x +6

Step-by-step explanation:

Step(i):-  

Given that the width of the rectangle = 2x - 2

Given that the length of the rectangle = y

Perimeter of the rectangle

                               P = 2 (length + width)

                                  = 2( y + 2x -2)

Given perimeter of the rectangle = 16 x +8

Step(ii):-

     2( y + 2x -2) = 16 x +8

⇒  2 y + 4x -4 = 16 x +8

⇒      2 y = 16x +8-4x+4

⇒      2 y = 12 x + 12

⇒       y = 6 x +6

The length of the rectangle = 6 x +6

For the experiment of rolling a fair dice, each face has an equal probability of showing up.

Let 'p' be the probability of getiing a particular face.

So the probability of rolling any of the 6 face is 'p'.

Now, the sum of all probability should be unity,

Thus, the probability of any face is 1/6.

Hence, it concludes that the theoritical probability of rolling a 2 is equal to 1/6.

The relationship between the circumference C of the circle in which the degree measure A of a central angle of a circle intercepts an arc length s of the arc is

B) C=360 degrees s over A

The relationship between the circumference C of a circle and the degree measure A of a central angle that intercepts an arc length s of the arc can be described by the formula:

s = A / 360 * C

Make C the subject of the formula

s = AC / 360

360s = AC

rearranging

AC = 360s

C = 360 degrees s / A

C = (s / A) * 360°

Answer:

\(\textsf{B)} \quad C=\dfrac{360^{\circ}\:s}{A}\)

Step-by-step explanation:

In a circle, the ratio of an arc length (s) to the circumference (C) is equal to the ratio of the measure of the arc's central angle (A) to 360°.

This is because:

Therefore, this can be expressed as:

\(\dfrac{s}{C}=\dfrac{A}{360^{\circ}}\)

Cross multiply:

\(360^{\circ} \cdot s=C \cdot A\)

Now, divide both sides by A to isolate C:

\(\dfrac{360^{\circ} \cdot s}{A}=C\)

Therefore, the relationship between the circumference (C) of the circle in which the degree measure (A) of a central angle of a circle intercepts an arc length (s) of the arc is:

Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 so option (A) will be correct.

The mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.

In other words, the mean is the foundation of the deviation of data from all data sets.

Mean = sum of data / Number of data

For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be

( 40 + 45+ 44 + 46 + 48) /5 = 44.6.

Given that,

Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 wins in a row

It means the top 200200200 longest streaks worldwide in June have an average longest streak of 636363.

Answer:

321.50 dollars.

Step-by-step explanation:

Dena is buying wallpaper. It costs $8.79 per meter. She needs 120 feet. How much will the wallpaper cost? Round to the nearest half dollar.

This is a tricky math problem that requires some conversions and calculations. First, we need to convert feet to meters, because Dena lives in a country that uses the metric system. According to the search results   , one foot is equal to 0.3048 meters. So, 120 feet is equal to 120 x 0.3048 = 36.576 meters.

Next, we need to multiply the length of the wallpaper by the price per meter to get the total cost. The total cost is 36.576 x 8.79 = $321.38.

Finally, we need to round the total cost to the nearest half dollar. This means we need to look at the cents part of the cost and see if it is closer to 0, 50 or 100. In this case, 38 cents is closer to 50 than to 0 or 100, so we round up the cost to $321.50.

Therefore, Dena will have to pay $321.50 for the wallpaper. That's a lot of money for some paper that will probably peel off in a few years! Maybe she should consider painting her walls instead.

The correct option on Hash 1 and Hash 2 is C. Hash 1 is designed to work with small input data, while Hash 2 is optimized for processing large input data.

The main difference between Hash 1 and Hash 2 is the amount of input data they can process. Hash 1 can process input data that is 2 characters long, while Hash 2 can handle input data that is up to 300,000 characters long. This means that Hash 2 is better suited for processing larger datasets than Hash 1.

In terms of which hash function is better suited for different types of data, it depends on the specific application and the characteristics of the data being processed. For example, if the data being hashed is small and of low complexity, Hash 1 may be a good choice due to its speed and simplicity.
