To calculate the geometric mean, we take their product instead: 1 x 5 x 10 x 13 x 30 = 19,500 and then calculate the 5-th root of 19,500 = 7.21. This is equivalent to raising 19,500 to the 1/5-th power. Another way to calculate the geometric mean is with logarithms, as it is also the average of logarithmic values converted back to base 10.

A recursive function allows us to find the value of any term in a geometric sequence by using the previous term in that exact sequence. If the common ratio of that geometric sequence is 9, then each term is nine times the previous term.

The general term for the geometric sequence is

an= a1 * r ^ (n-1)

where an is the nth term, a₁ is the first term, r is the common ratio, and n is its position or number. The term.

where a₁ = 3 and r = 3/2

Using supplementary angles, it is found that the value of x is of x = 10.75.

Supplementary angles are angles whose measures add to 180º.

An entire pizza is 360º, hence half the pizza is 180º, meaning that angles AOB and BOD are supplementary.

Their measures are given as follows:

Since they are supplementary, they add to 180º and we can add their measures and solve for x as follows:

2x - 4 + 14x + 12 = 180

16x = 172

x = 172/16

For the given subscriptions, we have that:

a) The mean is of $6.42.

b) The median is of $5.

c) The modes are of 5 and 10.

d) Marshall would have to add a subscription of $12.25.

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

For this problem, the observations are given as follows:

10, 5, 10, 4, 12, 5, 6, 2.75, 3.

Hence the mean is:

M = (10 + 5 + 10 + 4 + 12 + 5 + 6 + 2.75 + 3)/9 = $6.42.

With another observation, we want a mean of $7, hence:

(10 + 5 + 10 + 4 + 12 + 5 + 6 + 2.75 + 3 + x)/10 = 7

57.75 + x = 70

x = 12.25.

Hence, for item d:

Marshall would have to add a subscription of $12.25.

The median of a data-set is the middle value, which is the value that 50% of the data-set is greater and 50% is lesser.

The ordered data-set in this problem is:

2.75, 3, 4, 5, 5, 6, 10, 10, 12.

The middle value is of 5, which is the median.

The mode of a distribution is the observation that appears the most times in the distribution.

In this problem, those observations are 5 and 10, both of which appears twice, hence the distribution is bimodal.

Step-by-step explanation:

Given that,

→ Andrew ran 5 miles less than 2 times the no. of miles Bernadette ran.

Hence, option (a) is correct.

Regarding the piecewise curve and probabilities, we have that:

a) The figure is a value density curve because the area under the figure is of 1.

b) The probability is: P(0.6 ≤ X ≤ 0.8) = 0.2.

c) The probability is: P(0 ≤ X ≤ 0.4) = 0.6.

d) The probability is: P(0 ≤ X ≤ 0.2) = 0.3.

e) The median is the value of a for which P(0 ≤ X ≤ a) = 0.5, P(0 ≤ X ≤ 0.2) = 0.3 and P(0 ≤ X ≤ 0.4) = 0.6, hence the median of this density curve is a point between X=0.2 and X=0.4.

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, to the left of x = 0.4, we have a linear curve with:

Then, considering the constant:

To represent a distribution, it's area over the entire interval has to be of 1. The area is composed by.

Hence the total area is:

A = 0.8 x 1 + 0.5 x 0.4 x 1 = 1.

Hence:

The figure is a value density curve because the area under the figure is of 1.

For itens b to d, the probabilities are also given by areas, hence:

For item e, we have that:

The median is the value of a for which P(0 ≤ X ≤ a) = 0.5, P(0 ≤ X ≤ 0.2) = 0.3 and P(0 ≤ X ≤ 0.4) = 0.6, hence the median of this density curve is a point between X=0.2 and X=0.4.

The equation of the circle that passes through the point (-6 , -4) and has a center located at the origin is x^2 + y^2 = 52.

Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-6 , -4).

radius = distance = √(x2 - x1)^2 + (y2 - y1)^2

radius = √(-6 - 0)^2 + (-4 - 0)^2

radius= √36 + 16

radius = √52

The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.

Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.

(x - h)^2 + (y - k)^2 = r^2

Approximately [tex]0.7\; {\rm ft}[/tex].

Step-by-step explanation:

If the current bounce is of height [tex]h\; {\rm ft}[/tex], the next bounce would be of height [tex](78\%\, h)\; {\rm ft}[/tex], which is equal to [tex](0.78\, h)\; {\rm ft}[/tex].

It is given that the first bounce is of height [tex]6.5\; {\rm ft}[/tex]. Relative to this first bounce:

In general, the [tex]n[/tex]th bounce would have been dampened [tex](n - 1)[/tex] times. The height of that bounce would be [tex]((0.78)^{n - 1}\, 6.5)\; {\rm ft}[/tex].

We'd come along through a few specific terms in AP that had been labeled as:

As shown below, the AP can also be referred to in terms of common differences.

Now, as the values given in the question;

There are total 16 rows in the arena.

Thus, n = 16.

There are 20 seats present in row 1.

Consider the first term as 'a₁' = 20.

Similarly, there are 23 seats present at row 2.

Consider 'a₂' = 23 is the second term.

Now, calculate the common difference;

d = a₂ - a₁  

Put the values in the 'd'.

d = 23 - 20 = 3.

Now, compute the total number of seats in 16th row bu nth formula.

n-th term:  an = a + (n − 1) × d

a₁₆ = a₁ + (n - 1)d

a₁₆ = 20 + (16 - 1)3

a₁₆ = 20 + 45

a₁₆ = 65

Therefore, the total number of seats present in the 16th row is 65.
