The lower quartile can also be inferred to be 51.
The interquartile range can be found by subtracting the lower quartile from the upper quartile. The interquartile range is:
= Upper quartile - Lower quartile
= 72 - 51

A chord in circle T has a length of 16 cm and the diameter of the circle 20 cm. How far is the chord from the center of the circle
ANSWER
[tex]6\operatorname{cm}[/tex]EXPLANATION
First, let us make a sketch of the circle:
Since the diameter of the circle is 20 cm, the radius of the circle is 10 cm, as shown above.
The two radii and the chord of the circle form a triangle. Also, the distance from the center to the chord forms a right triangle with the radius and half the length of the chord:
Now, we can solve for d by applying the Pythagoras theorem:
[tex]10^2=d^2+8^2[/tex]Solve for d:
[tex]\begin{gathered} d^2=10^2-8^2 \\ d^2=100-64=36 \\ d=\sqrt[]{36} \\ d=6\operatorname{cm} \end{gathered}[/tex]That is the distance from the chord to the center of the circle.

As per the concept of probability,
a) There are 1757600 number of possible license plates can there be in this state if repetition of letters and numbers is permitted
b) There are 1404000 number of possible license plates can there be in this state if repetition of letters and numbers is not permitted.
Probability:
Probability refer the possible way of occurring the particular event.
Given,
License plates in a particular state are to consist of 2 digits followed by 3 uppercase letters.
Here we need to determine the number of possible license plates for both repetition phase and non repetition phase.
Here we know that, license plates consist of 3 letters followed by 2 digits.
Let us consider the numbers on license plates be N
Let us consider the letters on license plates be L
Then the license plate consisting of 3 letters and 2 digits will be writen as,
=> LLLNN.
We know that the letters can be anything from A to Z.
There are 26 letter combinations for the first letter.
Again second and third letters can be anything from the 26 letters.
So, combination for letters = 26 × 26 × 26 = 17576
Similarly, the numbers can be anything from 0 to 9.
There are 10 combinations for both places.
Then the combination for numbers = 10 × 10 = 100
Therefore, the total number of combination for letters and numbers
=> 17576 × 100 = 1757600.
Therefore, there are 1757600 license plates can be made with repetition.
Similarly, for non repetition mode,
The number of letters for each place is reduced before,
So, the combination for the letter is,
=> 26 x 25 x 24 = 15600
Similarly, the combination of numbers is,
=> 10 x 9 = 90
Therefore, the total number of combination is,
=> 15600 x 90 = 1404000

In order to calculate the percentage that enjoy New Years Eve only, we can use the diagram and formula below:
Using F to represent Fourth of July, N to represent New Years Eve and M to represent Memorial Day, the formula is:
[tex]P(N\text{ only})=P(N)-P(F\text{ and }N)-P(M\text{ and }N)+P(all\text{ }three)[/tex]From the given data, we have:
P(N) = 28% = 0.28
P(F and N) = 18% = 0.18

m ∠6 = 55°
Step-by-step explanation:
Angles 2 and 6 are corresponding angles and equal
m ∠2 + 125° = 180° since they are linear supplementary angles
m ∠2 = 180 - 125 = 55°
Since m ∠2 = m ∠6
m ∠6 is also 55°

From the above graph, we have the following points
(x₁, y₁) = (0, 0)
(x₂, y₂) = (3, -6)
The slope of a line can be calculated using the following slope formula
Slope = (y₂ - y₁)/(x₂ - x₁)
Where
(x₁, y₁) = (0, 0) and (x₂, y₂) = (3, -6)
Substitute the known values in the above equation
So, we have the following equation

different life applications like economy, medicine, engineering, etc...
Calculus in real life applications is highly common in the engineering industry.
Structural engineering is one of calculus' most important practical applications. Calculus is used to determine structural requirements for earthquake design, stresses in intricate structural combinations, and heat loss in buildings. Calculus is used by architects to determine the crucially critical amount of materials needed to build support systems that can endure stress for extended periods of time. Calculus was used to foresee the effects of wind resistance when building famous structures like the Eiffel Tower.
Beams, tension, and compression members are the three structural components that civil engineers must take into account while building bridges. Calculus can be used to calculate the amount of force exerted on the beam, taking into account the weight of vehicles, pedestrians, and projected traffic on the bridge. The materials, size, and capacity can be calculated based on these variables.

b) Draw the asymptote.
c) Write the equation of the asymptote.
I need help with question c only
Answer:
y = 2
Step-by-step explanation:
A horizontal asymptote is a horizontal line that the graph of a function approaches as x approaches ±∞.
Mathematically we write this as
[tex]f(x) \rightarrow a \text{ as } x \rightarrow \infty \text{ or } x \rightarrow -\infty[/tex]
A vertical asymptote at some constant a is where the function approaches ±∞.
Mathematically
[tex]f(x) \rightarrow \infty \text { or } f(x) \rightarrow -\infty \text{ as } x \rightarrow a[/tex]
The given function y = 2ˣ + 2 is an exponential function and exponential functions do not have a vertical asymptote
The horizontal asymptote can be found by determining what the function limit is as [tex]x \rightarrow \pm \infty[/tex]
As [tex]x \rightarrow +\infty[/tex] the function [tex]\rightarrow \infty[/tex]
As [tex]x \rightarrow -\infty[/tex] , [tex]2^x \rightarrow 0\\\\\\2^x + 2 \rightarrow 2\\\\[/tex]
So the equation for the horizontal asymptote is y = 2
The graph shows that at y = 2, the function is parallel to the line but does not touch the line

The polar equation r = 7 sin (2theta) graphs as a rose.What is the length of the petals of this rose?Enter your answer in the box.
This problem is about a polar equation. It's important to know that polar coordinates depend on two variables, the angle of the vector and its distance.
[tex](r,\theta)[/tex]Where r represents the distance and theta represents the angles.
In this case, the angle is 20°, according to the problem.
So, first, we need to graph this equation in the polar system, to then measure the length of the petals
[tex]r=7\sin (2\theta)[/tex]The graph of this equation is shown in the image attached below.
In the image above, you can observe the polar equation graphed, with the coordinated system behind, this will allow us to find the length of each (which are symmetrical). You can observe that the petal on the third quadrant is at (-5,-5).
Now, we use the following formula to find the distance
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Replacing the points, we have
[tex]d=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}=\sqrt{2(25)}=5\sqrt{2}\approx7.07[/tex]Therefore, the length of each petal is 7.07 units, approximately.The lines y=0.5x + 8 and y = 5-x are shown graphed to the right.

As we can see in the graph, the lines intersect in the ordered pair (-2,7). Then, the solution to the system comprised of these two lines is:
[tex]\begin{cases}x=-2 \\ y=7\end{cases}[/tex]MathematicallyTo solve the given system of equations, we can use the equalization method.
