Here is a frequency distribution table (FDT) for a small data set: data value frequency 14 14 15 11 16 23 17 10 18 13 Find the following measures of central tendency: mean (I (Please show your answer to one decimal place.) median (Please enter an exact answer:) mode (Please enter an exact answer: )
The mean is 14.7, the median is 16, and the mode is 16.
To find the mean, we need to calculate the sum of all the data values and divide it by the total number of observations.
The sum of the data values is:
14 x 14 + 15 x 11 + 16 x 23 + 17 x 10 + 18 x 13 = 196 + 165 + 368 + 170 + 234 = 1043
The number of observations is:
14 + 11 + 23 + 10 + 13 = 71
The mean is calculated as follows,
1043 / 71 = 14.7 (rounded to one decimal place)
The median is the central value in the data collection. To find the median, we need to arrange the data values in ascending order and find the middle value. In this case, we have an odd number of observations, so the median is simply the middle value.
14, 14, 15, 15, 16, 16, 16, 16, 16, 16, 16, 17, 17, 18, 18, 18
The median is 16.
The mode is the value that appears most repeatedly in the data set. In this case, the mode is 16 since it occurs the most (23 times).

Let's roll two dice and find the probability of rolling a certain sum. Is this a simple or compound event?
Two dice - Red and Blue
Recall that a simple event has one and only one outcome of interest. In this example, we are rolling two dice, but we are only interested in one outcome, the sum of the two dice. This is a simple event.
What is the probability of:
Rolling a sum of 1?
Rolling a sum of 3?
Rolling a sum of 12?
Rolling a sum of 7?
Since we are rolling a pair of dice and looking for the sum, the sample space is a little more complicated than rolling one die. The chart below will help us determine the possible outcomes. The top row indicates the numbers on the sides of the blue die and the first column represents the number on the sides of the red die. The white area indicates the sum of the numbers in the row and column.

A shredding machine can shred 20 sheets of paper in 14 seconds. The bin has room
for 1000 sheets of shredded paper.
How long will it take to fill the bin if the machine has to stop for 3 minutes after every
200 sheets to prevent overheating?
Answer:
See below
Step-by-step explanation:
Rate = 20 sheets / 14 seconds = 10/7 sheet / sec
every 200 sheets is 4 rest periods = 12 minutes
1000 sheets / (10/7 sheet/ sec) + 12 min
700 seconds + 12 minutes
= 700 seconds + 720 seconds = 1420 seconds = 23 min 40 sec

The graph to the right is the uniform probability density function for a friend who is x minutes late. (a) Find the probability that the friend is between 10 and 30 minutes late. (b) It is 10 A.M. There is a 20% probability the friend will arrive within how many minutes? part a) what is the probability that the friend is between 10 and 30 minutes late_?
The probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.
Since the probability density function is uniform, the probability of the friend being between 10 and 30 minutes late is equal to the area of the rectangle that lies between x = 10 and x = 30, and below the curve of the probability density function.
The height of the rectangle is equal to the maximum value of the probability density function, which is 1/30 since the interval of possible values for x is [0, 30] minutes.
The width of the rectangle is equal to the difference between the upper and lower limits of the interval, which is 30 - 10 = 20 minutes.
Therefore, the probability of the friend being between 10 and 30 minutes late is:
P(10 < x < 30) = (height of rectangle) x (width of rectangle)
= (1/30) x 20
= 2/3
≈ 0.6667
So the probability that the friend is between 10 and 30 minutes late is approximately 0.6667, or 66.67%.

The equation of a parabola is (x−3)2=16(y+7) . What are the coordinates of the vertex and focus of the parabola? What is the equation of the directrix?
The coordinates of the vertex of the parabola are (3, -7). The focus of the parabola is located at (3, -3). The equation of the directrix is y = -11.
The given equation of the parabola is in the form (x - h)^2 = 4p(y - k), where (h, k) represents the vertex and p represents the distance between the vertex and the focus/directrix.
Comparing the given equation with the standard form, we can see that the vertex is at (3, -7).
The coefficient 4p in this case is 16, so p = 4. Since the parabola opens upward, the focus will be p units above the vertex. Therefore, the focus is located at (3, -7 + 4) = (3, -3).
To find the directrix, we need to consider the distance p below the vertex. Since the parabola opens upward, the directrix will be p units below the vertex. Hence, the equation of the directrix is y = -7 - 4 = -11.
In summary, the coordinates of the vertex are (3, -7), the focus is located at (3, -3), and the equation of the directrix is y = -11.

The smallest positive solution of tan bx = 2 is x = 0.3. Determine the general solution of tan bx = 2.
The general solution of \(\tan bx = 2\) and \(x = 0.3\) is \(x = 0.095\pi \mp 0.271\pi\cdot i\), \(\forall \,i\in \mathbb{N}_{O}\).
From Trigonometry we remember that Tangent is a Transcendental Function that is positive both in 1st and 3rd Quadrants and have a periodicity of \(\pi\) radians. The procedure consists in using concepts of Direct and Inverse Trigonometric Functions as well as characteristics related to the behavior of the tangent function in order to derive a General Formula for every value of \(x\), measured in radians.
First, we solve the following system of equations for \(b\):
\(\tan bx = 2\) (1)
\(x = 0.3\) (2)
Please notice that angles are measured in radians.
(2) in (1):
\(\tan 0.3b = 2\)
\(0.3\cdot b = \tan^{-1} 2\)
\(b = \frac{10}{3}\cdot \tan^{-1}2\)
\(b\approx 3.690\)
Under the assumption of periodicity, we know that:
\(y = \tan bx\)
\(b\cdot x \pm \pi\cdot i = \tan^{-1} y\), \(\forall \,i\in \mathbb{N}_{O}\)
\(b\cdot x = \tan^{-1}y \mp \pi\cdot i\)
\(x = \frac{\tan^{-1}y \mp \pi\cdot i}{b}\)
If we know that \(y = 2\) and \(b \approx 3.690\), then the general solution of this trigonometric function is:
\(x = \frac{0.352\pi \mp \pi\cdot i}{3.690}\), \(\forall \,i\in \mathbb{N}_{O}\)
\(x = 0.095\pi \mp 0.271\pi\cdot i\), \(\forall \,i\in \mathbb{N}_{O}\)
The general solution of \(\tan bx = 2\) and \(x = 0.3\) is \(x = 0.095\pi \mp 0.271\pi\cdot i\), \(\forall \,i\in \mathbb{N}_{O}\).

*Hint: Divide the shape into 2! You will need to use trig!
Check the picture below.
so hmm we have a 6x6 square atop and a triangle with base of 6 and a height of "h", let's get "h".
\(\sin( 42^o )=\cfrac{\stackrel{opposite}{h}}{\underset{hypotenuse}{2}} \implies 2\sin(42^o)=h \implies 1.34\approx h \\\\[-0.35em] ~\dotfill\\\\ \stackrel{ \textit{\LARGE Areas} }{\stackrel{triangle}{\cfrac{1}{2}(\underset{b}{6})(\underset{h}{1.34})}~~ + ~~\stackrel{ square }{(6)(6)}} ~~ \approx ~~ 4.02+36~~ \approx ~~ \text{\LARGE 40.0}\)
Solve the quadratic equation 3x²+2x-4=0
Auuuu.........
