The mode frequency can be a useful tool for understanding the distribution of the data and identifying any outliers or anomalies in the data set.

The mode frequency of the age variable refers to the most frequently occurring age in a given set of data. This measure of central tendency is particularly useful when working with categorical data, such as age ranges.

To calculate the mode frequency, one must first organize the data into a frequency distribution table, which lists all the different ages and the number of times each occurs. The age with the highest frequency is then considered the mode frequency.

For example, if there are 100 individuals in a data set and the ages range from 20 to 60, we would organize the data into age ranges, such as 20-29, 30-39, etc. Then we would count how many individuals fall into each age range and record this information in the frequency distribution table.

If the age range with the highest frequency occurs more than once, we have a multi-modal data set. On the other hand, if there is only one mode frequency, the data set is considered unimodal.

When it is third and long, the best move is typically to make a long pass to a wide receiver because it has the probability to gain the greatest yardage.

Throwing the ball far downfield is frequently the best move when the team has to gain a lot of yardage to continue the drive on third and long. The most yards may be gained by a deep pass to a wide receiver since it might extend the action past the original line of scrimmage. The prospect of a huge play, in which the receiver catches the ball and runs for a bigger gain, is also made possible. A deep pass might also throw the defense off because they might not be anticipating the offense to go for a long gain. But a deep pass can also be dangerous because it might result in a turnover if the receiver doesn't pay attention.

The surface area of an egg shell scales as the mass of the egg shell raised to 1.82694

The term surface area in math is defined as the area occupied by a three-dimensional object by its outer surface

Here we know that the area of a cube with edged is proportional to the second power d² while its volume is proportional to the third power d³.

Here we know that for any bounded solid object, here we have which encloses a region with some volume V and its enclosing surface has area A, where as the same kind of proportions can be derived in terms of a linear dimension d of the object, here for example the diameter of the object.

AS we all know that the surface area is directly proportional to the 3rd power of the mass of the egg, here we have A = km³ where A is the surface area, k a constant of proportionality, and m the mass.

For a chicken egg we have 28 = k(60)⁰°⁶⁷

Here by solving for k we get:

=> k = 28/60⁰°⁶⁷ ≈ 1.82694

At a price of $44, the quantity demanded is equal to q*, which is 30 units.

The market for good X is given with a price of $15 at q0 (10 units), a price of $21 at pa, a price of $31 at p* (30 units), a price of $44 at pb, a price of $57 at p1 (50 units), and a price of $70 at q2 (70 units). To calculate the quantity demanded when the price is $44, we first need to identify the price points on either side of $44. In this case, $31 and $57 are the two price points. We then look at the corresponding quantities at those two points, which are q* (30 units) and q1 (50 units). Since the demand curve is downward sloping, the quantity demanded at $44 (pb) will be between 30 and 50 units. Since 30 is the lower number, the quantity demanded at $44 will be q*, or 30 units.

The tangent of the angle between vectors v and w is 2√(21) / 9

We can use the dot product and cross-product formulas to find the angle between two vectors.

The dot product of two vectors v and w is given by:

v · w = ||v|| ||w|| cos(θ)

where ||v|| and ||w|| are the magnitudes of the vectors v and w, and θ is the angle between them.

The cross product of two vectors v and w is given by:

v × w = ||v|| ||w|| sin(θ) k

where k is a unit vector in the direction of the cross product.

Since v × w = 6i - 7j + 9k and v · w = 9, we can find the angle between v and w as follows:

[tex]\theta = sin^{-1}\frac{||v \times w||}{||v|| \ ||w||} = sin^{-1}\frac{||6i - 7j + 9k||}{||v|| \ ||w||}[/tex]

We can find the magnitude of v × w by using the formula for the magnitude of a cross-product:

[tex]||v \times w|| = ||6i - 7j + 9k|| \\\\= \sqrt{6^2 + (-7)^2 + 9^2} = \sqrt{6^2 + 49 + 9^2}\\\\=\sqrt{84} = \sqrt(2^2 \times 3 \times 7) = 2\sqrt{(3 \times 7)[/tex]

We can find the magnitude of v and w using the given dot product formula:

v · w = ||v|| ||w|| cos(θ) = 9

||v|| ||w|| = 9 / cos(θ)

Since we know that ||v|| and ||w|| are positive, we can square both sides to obtain:

[tex](||v|| \ ||w||)^2 = \frac{9 }{cos(\theta))^2} \\\\||v||^2 \ ||w||^2 = \frac{81}{cos^2(\theta)}[/tex]

Finally, using the tangent formula, we can find tanθ:

tan(θ) = sin(θ) / cos(θ) = ||v × w|| / ||v·w|| = 2√(3 × 7) / 9 = 2√(21) / 9.

The test statistic to test the claim that the standard deviation of all customer waiting times is greater than 3.5 minutes, 7.444

Standard deviation is a measure of the spread or dispersion of a set of data. It quantifies how much the individual data points in a set deviate from the mean (average) value of the set. In other words, it tells you how much the data is scattered around the mean.

The test statistic to test the claim that the standard deviation of all customer waiting times is greater than 3.5 minutes can be calculated using the following formula:

Z = (s / σ) x √n

where s is the sample standard deviation (4.8 minutes), σ is the population standard deviation (3.5 minutes), and n is the sample size (15).

Z = (4.8 / 3.5) x √15

Answer:

To figure out how many adults and children bought tickets, we can set up a system of equations using the information provided. Let x be the number of adults and y be the number of children. We know that:

x + y = 500 (because a total of 500 people bought tickets)

17.95x + 12.95y = 7355 (because the total revenue from ticket sales is $7355)

We can use the first equation to solve for one of the variables in terms of the other variable. For example, we can substitute y = 500 - x into the second equation:

17.95x + 12.95(500 - x) = 7355

This simplifies to:

17.95x + 6475 - 12.95x = 7355

5x = 1880

x = 376

so there are 376 adults bought tickets and 500-376=124 children bought tickets.

Answer:

m= -3/2

Step-by-step explanation:

To find slope

[tex]m \: = \frac{y2 - y1}{x2 - x1} [/tex]

We have our x1 and y1 of (2,5)

We have our x2 and y2 of (8,-4)

Now we plug in

= (-4-5)/(8-2)

= (-9)/(6)

Simplifying it would be

[tex]m = - \frac{3}{2} [/tex]

Answer: slope 'm' = -3 / 2

Step-by-step explanation: Using the formula m=(y2-y1)/(x2-x1), where 'm' is the slope of the line connecting the two points, we can plug in our x and y values:

x1 = 2

x2 = 8

y1 = 5

y2 = -4

Once we plug in our x and y values, we get the equation

m = (-4 - 5) / (8 - 2)

--> -9 / 6 (We can simplify this fraction to get or answer of -3 / 2)

What is vector ?

A vector is a mathematical object that has both magnitude (or length) and direction. Vectors can be used to represent physical quantities such as velocity, force, or displacement, where the magnitude represents the size of the quantity and the direction represents its orientation in space.

Let n1 and n2 be the normal vectors of the two planes, respectively.

The normal vectors are:

n1 = <5, -4, -1> and n2 = <5, -4, 1>.

The projection of n1 onto n2 is:

projn1 onto n2 = (n1 . n2 / ||n2||^2) * n2 = (n1 . n2 / ||n2||^2) * (n2 / ||n2||) = (n1 . n2 / ||n2||) * n2 / ||n2|| = (n1 . n2) * n2 / ||n2||^2.

The dot product of n1 and n2 is:

n1 . n2 = 5 * 5 + (-4) * (-4) + (-1) * 1 = 25 + 16 + 1 = 42.

The magnitude of n2 is:

||n2|| = sqrt(5^2 + (-4)^2 + 1^2) = sqrt(30).

Therefore, the projection of n1 onto n2 is:

(n1 . n2) * n2 / ||n2||^2 = 42 * <5, -4, 1> / 30 = <7/3, -4/3, 7/30>.

So , The distance between the two planes 5x−4y−z=65x−4y−z=6 and 4y−5x z=−484y−5x z=−48 is sqrt(7/10).
