What is the explanations

The positions of third quartile (Q3), second quartile (Q2) and first quartile (Q1) are 75th, 50th and 25th respectively.

Hence the correct option is (D).

Given the size if the set of data is 99.

99 is an odd number so the second quartile of the data set is given by (Q2)

= The value of the ((99 + 1)/2) th observation from ascending order arrangement

= The value of the 50 th observation from ascending order arrangement

So the second quartile divide the data set in to two equal observation set with number of observations 49.

The first quartile is (Q1) = The value of the ((99 + 1)/4) th observation = The value of 25 th observation

The third quartile is (Q3) = The value of the (3*(99 + 1)/100) th observation = The value of 75 th observation.

Answer:

Step-by-step explanation:

The circumference of the bicycle wheel can be determined by the formula:

Circumference = π x diameter

where π (pi) is a mathematical constant equal to approximately 3.14.

Substituting the given diameter of 1.25 ft, we get:

Circumference = 3.14 x 1.25 ft

Circumference = 3.925 ft (rounded to three decimal places)

Each revolution of the wheel covers a distance equal to the circumference of the wheel. Therefore, if the odometer recorded 254 revolutions, the distance covered by the bicycle is:

Distance = 254 x Circumference

Distance = 254 x 3.925 ft

Distance = 996.95 ft (rounded to two decimal places)

Therefore, the bicycle traveled approximately 996.95 feet.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0.

Several real-world scenarios use exponential functions, including population increase, compound interest, radioactive decay, and the spread of diseases. For instance, an exponential function may be used to simulate the expansion of a bacterial population, with the rate of increase being proportional to the population size. Similarly, compound interest, which applies the rate of interest to the principal sum across a number of periods, can be represented by an exponential function.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0 and k translates the graph of f up when k > 0 and down when k < 0.

The given statement "A reaction that has K_eq = 2.0 × 10^(-8) will have high concentrations of products" is false because a low value of K_eq indicates a greater concentration of reactants compared to products.

The equilibrium constant, K_eq, represents the ratio of product concentrations to reactant concentrations at equilibrium. In this case, a K_eq value of 2.0 × 10^(-8) suggests that the concentration of products is significantly lower compared to the concentration of reactants.

This implies that the reaction favors the formation of reactants rather than products. Therefore, the statement is false as it states that the reaction will have high concentrations of products, which is contradictory to the low K_eq value provided.

Answer:

Discontinuity at (1, 7), zero at (-4/3 , 0)

Step-by-step explanation:

\(3x^{2} + x - 4\) = (3x + 4)(x - 1) = 0

                        x = -4/3   or 1

But x = 1 makes f(x) undefined, so there is discontinuity at x = 1

and there is a zero at x = -4/3.

3x + 4 = 3(1) + 4 = 3 + 4 = 7

If you were to graph this function, then you would get the line y = 3x + 4 with a hole at (1, 7).   The line would cross the x-axis at (-4/3, 0) with discontinuity at (1, 7)

The formula for the height of the banner in terms of the side length of the cardboard square, the height of the grandstand, and the distances from the person's eye level to the grandstand and the ground.

Mathematically, we can write this as:

(height of banner) / (distance from eye level to top of grandstand) = (side length of cardboard square) / (distance from eye level to bottom of square)

So, the distance from the eye level to the top of the grandstand is "s + h". We also know the distance from the person's eye level to the bottom of the square, which is "d₂ - d₁".

Putting all of this together, we can write:

(height of banner) / (s + h) = s / (d₂ - d₁)

To solve for the height of the banner, we can cross-multiply and simplify:

(height of banner) = (s² / (d₂ - d₁)) * (1 + h/s)

The sampling error or sampling variability is the discrepancy between the sample and group norms.

Among the most frequent kinds of sampling mistakes is sampling prejudice. When the sample's participants are not indicative of the general community, it happens. A poll has sampling bias if it only includes respondents from one region of the nation and does not include respondents from the other regions.

For instance, the mother, kids, or the complete family could be the populace in a poll on breakfast cereals. Selection Error: Occurs when respondents self-select their involvement in the poll, suggesting that only the people who are eager are participating.

A cylinder and a cone are two common three-dimensional geometric shapes. Volume cylinder =\(36π ft^3\). The volume of Come is = \(15π ft^3\). Total Volume is  = \(51π ft^3.\)

To find the exact volume of the figure, we need to calculate the volume of the cylinder and the volume of the cone separately, and then add them together.

1. Volume of the Cylinder:
The cylinder has a height of four feet and a radius of three feet. The formula to calculate the volume of a cylinder is

\(V = πr^2h\),

where V is the volume, r is the radius, and h is the height.

Plugging in the values, we get

The volume of the Cylinder = \(π(3^2)(4)\)

\(= 36π ft^3.\)

2. Volume of the Cone:
The cone has a radius of three feet and a height of five feet. The formula to calculate the volume of a cone is

V = \((1/3)πr^2h\),

where V is the volume, r is the radius, and h is the height.

Plugging in the values, we get

Vcone = \((1/3)π(3^2)(5)\)

\(= 15π ft^3.\)

3. Total Volume:
To find the total volume of the figure, we add the volume of the cylinder and the volume of the cone:

Answer:

56.7

Step-by-step explanation:

Hello There!

Trigonometric Ratios

sin = opposite divided by hypotenuse

cos = adjacent divided by hypotenuse

tan = opposite divided by adjacent

we need to find x and we are given its opposite side length and the hypotenuse

so the trigonometric ratio we need to use is sin

knowing that sin = opposite side divided by hypotenuse we create an equation

\(sin(x)=\frac{51}{61}\\\frac{51}{61} = .8360655738\\arcsin(sinX)=x\\arcsin(.8360655738)=56.72695659\)

our final step is to round to the nearest tenth of a degree

so we can conclude that the measure of angle A is 56.7

note: arcsin = inverse of sin

Step-by-step explanation:

To determine the probability of selecting a number less than 5, given that the number is less than 6, we need to consider the numbers that satisfy both conditions.

In this case, since the condition is "less than 6," we only need to focus on the numbers 1, 2, 3, 4, and 5.

Out of these numbers, the numbers that are less than 5 are 1, 2, 3, and 4. So, there are four favorable outcomes (numbers less than 5) out of the five possible outcomes (numbers less than 6).

Therefore, the probability of selecting a number less than 5, given that the number is less than 6, is 4/5 or 0.8.

To summarize:

Favorable outcomes (numbers less than 5): 1, 2, 3, 4

Possible outcomes (numbers less than 6): 1, 2, 3, 4, 5

Probability = favorable outcomes / possible outcomes = 4/5 = 0.8

The premise is that the French Revolution did not happen in 1771, and the conclusion is that it must have happened in 1988. This conclusion is logically valid because it necessarily follows from the given premise.

However, it is important to note that the argument does not provide any evidence or support for why the French Revolution would have happened in 1988, so the conclusion may not necessarily be true.

The expression that has the element of A*B*B is Option A - (b,2,3)

Sets are groups of clearly defined objects or elements in mathematics. A set is denoted by a capital letter, and the cardinal number of a set is enclosed in a curly bracket to indicate how many members there are in a finite set.

The "elements" of a set are the objects that make up the collection. Sets are equal if and only if they have the same elements, therefore a = A denotes that 'a' is one of A's elements. For sets, repetition and order are irrelevant.

Given, A={a.b} and B=[1,2,3]

Since the required expression was supposed to have the element of A*B*B the correct option would be A since it has elements b from A, 2 from B, and 3 from B, fulfilling all the required elements.

There are 5 different ways for him to get 3 or more heads:

HHHT

HHTH

HTHH

THHH

HHHH

Therefore the probability is 5/16

a. To determine the probabilities associated with different service lives, we can use the properties of the normal distribution. Given that the mean service life is six years with a standard deviation of one-half year, we can calculate the probabilities as follows:

(1) Probability of service lives of at least five years:

We need to calculate the area under the normal curve to the right of five years. Using the Z-score formula, we find the Z-score corresponding to five years: Z = (5 - 6) / 0.5 = -2. We can then look up the corresponding probability in a standard normal distribution table or use statistical software to find the probability associated with a Z-score of -2. This gives us the probability of service lives of at least five years.

(2) Probability of service lives of exactly six years: Since the service life follows a normal distribution, the probability of exactly six years is zero since it is a continuous distribution. We can assign a very small positive probability to approximate "exactly" six years. (3) Probability of service lives of seven and one-half years: Similarly, we calculate the Z-score corresponding to seven and one-half years: Z = (7.5 - 6) / 0.5 = 3. We find the probability associated with a Z-score of 3 to determine the probability of service lives of seven and one-half years or longer. b. If the manufacturer offers service contracts of four years, we want to find the percentage of televisions that fail from wear-out during this period. We can calculate this by finding the area under the normal curve to the left of four years. Using the Z-score formula, we find the Z-score corresponding to four years: Z = (4 - 6) / 0.5 = -4. The corresponding probability gives us the percentage of televisions expected to fail during the four-year service period.

c. To achieve an expected wear-out rate of 2 percent or 5 percent, we need to determine the service period corresponding to these rates. We can use the Z-score formula in reverse to find the Z-score that corresponds to the desired wear-out rate. From there, we can calculate the corresponding service period by rearranging the Z-score formula and substituting the desired wear-out rate and the given mean and standard deviation values.
