The correct option is (b) sample size.

In the formula for calculating the standard deviation, the letter n represent  sample size.

What is standard deviation?

Standard deviation is a statistical standard measure in finance that, when applied to an investment's annual rate of return, sheds light on its historical volatility.

Some key features regarding the standard deviation are-

A square root of a value deduced from correlating data points to a population's collective mean is used to calculate standard deviation. The formula is:

Standard Deviation = [tex]\sqrt{\frac{summation n to i=1 (x_{i}-bar x )}{n-1} }[/tex]

Where,

[tex]x_{i}[/tex]= value of the i th point the the given data set.

[tex]barx[/tex]= mean value

n = total number of data points.

Thus, the standard deviation, on the other hand, determines all ambiguity as risk, even when it is in the investor's favor, like above-average returns.

A surveyor asks a friend her opinion and then asks for the names of five friends for obtain additional opinions. This is an example of convenience sampling.

Sampling is the process of choosing the group from which you will actually collect data for your study. For instance, you could interview a sample of 100 students if you were examining the viewpoints of students at your university. With the help of sampling, you can test a statistical hypothesis on the features of a population.

An elementary illustration of a convenience sampling technique is when businesses hand out their marketing materials and conduct interviews with randomly chosen participants at a mall or on a busy street.

Answer:

e = 40h

After eleven hours, she will earn $440.00

Step-by-step explanation:

Let e = earnings

Let h = hours

e = 40h  She earns 40 for every hours that she tutors.  If she tutors for 11 hours, you would substitute aa for h to calculate her earnings.

e = 40(11)

e = 440

The volume of prism L is 750 cm³

A prism is a three-dimensional solid, that has two identical bases, rectangular or parallelogram-shaped faces, and the same cross-section.

The formula for the volume of a prism is V=Bh,

where B = base area and h = height.

We have,

Two similar prism

Prism L:

Length = 8 cm

Prism M:

Length = 20 cm

Volume = 1875 cm³

Applying the volume formula:

V = Bh

Base area = Length x width

1875 = Length x width x height

1875 = 20 x width x height

Width x height = 1875 / 20 = 93.75 _______(1)

Since prisms are similar we can use (1) in finding the Volume of prism L.

The volume of prism L:

= Length x width x height

= 8 x 93.75

= 750

Thus the volume of prism L is 750 cm³

The cycle route  for the triathlon is of 26 miles

A triathlon is an athletic event which involves races which involves of swimming, cycling, and running over various distances

According to the given data,

The most common triathlon distance for Bicycle route is 40 kilometers

1 mile = 1 .6 kilometer

Now we know that 1.6 kilometer is 1 mile

So we are required to convert kilometers of triathlon race into  miles

Therefore, 40 kilometers in mile will be= 40/1.6 = 25 miles

The vertical asymptote of the function = ln(x-6) + 5 is option C: x = 6.

The given function is f(x) = ln(x - 6) + 5.

A vertical asymptote is a vertical line that a function approaches but never crosses as it approaches infinity or negative infinity. For a logarithmic function like ln(x), the domain of the function is restricted to positive values only since the natural logarithm is undefined for non-positive arguments.

In the given function, we have f(x) = ln(x - 6) + 5. To find the vertical asymptote, we need to identify the value of x that would make the argument of the natural logarithm equal to zero.

Let's set the argument of the natural logarithm to zero:

x - 6 = 0

Now, solve for x:

x = 6

Thus, the value of x that would make the argument of the natural logarithm zero is x = 6.

So, the correct answer is option C: x = 6.

This means that the vertical asymptote of the function f(x) = ln(x - 6) + 5 is the vertical line x = 6. As x approaches 6 from either side (but never equaling 6), the function's values approach infinity. Similarly, as x approaches negative infinity, the function's values also approach infinity. The function never crosses the vertical line x = 6.

Answer:

n = 18

Step-by-step explanation:

The sides in a regular polygon are equal in length.

⇒ BC = CD

If BC = CD then ΔDCB is an isosceles triangle.

As the base angles of an isosceles triangles are equal:

⇒ ∠DBC = ∠BDC = 10°

Interior angles in a triangle sum to 180°.

⇒ ∠DBC  +∠BDC + ∠DCB = 180°

⇒ 10° + 10° + ∠DCB = 180°

⇒ 20° + ∠DCB = 180°

⇒ ∠DCB = 180° - 20°

⇒ ∠DCB = 160°

Therefore, the interior angle of the regular polygon is 160°.

The interior angles of a regular polygon are equal in size.

[tex]\boxed{\begin{minipage}{5.2 cm}\underline{Interior angle of a polygon}\\\\$\dfrac{(n-2) \times 180^{\circ}}{n}$\\\\where $n$ is the number of sides.\\ \end{minipage}}[/tex]

To find the number of sides, equate the formula to the found value of the interior angle and solve for n:

[tex]\begin{aligned}\implies\dfrac{(n-2) \times 180^{\circ}}{n} & =160^{\circ}\\(n-2) \times 180^{\circ} & =n \times 160^{\circ}\\ 180(n-2) & = 160n\\180n-360 & = 160n\\180n & = 160n+360\\180n-160n & = 360\\20n & = 360\\n &= \dfrac{360}{20}\\n & =18\\\end{aligned}[/tex]

Therefore, the regular polygon has 18 sides.

The correct option is D. 2x + 7 is used for solving the equation by substitution.

The following are the two given equations;

4x = 5 - 2y  .......equation 1

y - 2x = 7    .......equation 2;

using substitution mean put the value of one variable from 1 equation into the other.

Consider equation 2;

y - 2x = 7

y = 2x + 7  

Put this in equation 1;

4x = 5 - 2y

4x = 5 - 2(2x + 7)

Simplifying;

4x = 5 - 4x - 14

4x = 9 - 4x

8x = 9

x = 9/8

Therefore, the value of x is obtained as 9/8 for which the equation used is (y = 2x + 7).

Answer:

See below

Step-by-step explanation:

A function is continuous within an interval if its first derivative exists
[tex]\text{The first derivative of }\dfrac{2x+3}{x\:-\:2} = \dfrac{d}{dx}\left(\dfrac{2x+3}{x\:-\:2}\right) = -\dfrac{7}{\left(x-2\right)^2}[/tex]

Let's call this first derivative g(x)

g(x) is defined at all values of x except at x=2 since at this value the denominator becomes 0 and g(x) is not defined.

So the function has a discontinuity at x = 2

But in the interval (2, ∞ ) the function g(x)  always has a real value so f(x) is continuous in that interval
