Answer: The middle number in a data set when the data are put in order.
Answer and Step-by-step explanation:
To find the median of a set of numbers, you need to find what the number in the center is in a listed group of numbers. I'll use the example of these numbers:
6, 9, 5, 4, 3, 4, 2.5, 8, 0, 1, 5.
First, we need to organize the numbers in numerical order to find the median.
0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.
It would be the most simple and helpful to cross out each number until we get our center number; the median. (I can't cross the numbers out, so I'll underline them instead.) When crossing out, both sides need to be full of equally crossed out numbers.
0, 1, 2.5, 3, 4, 4, 5, 5, 6, 8, 9.
The number in the center for this example problem is 4. Thus meaning that our median is 4.
Sometimes though, it is not always a whole number. Sometimes you'll have to find the median in between two numbers. For example, let's just say you got stuck between 4 and 5. Then the median for that set of data would be 4.5, because it is still in the middle of the two.
I hope that this helps, let me know if you have any more questions about this topic.
find the value of X. then find the measure of angles B and C
Answer:
x = 20, m∠B = 92°, m∠C = 40°Step-by-step explanation:
Sum of the angles of any triangle is 180°:
m∠A + m∠B + m∠C = 180°Substitute the given values and solve for x:
48 + 6x - 28 + 2x = 1808x + 20 = 1808x = 160x = 20Find the missing angles:
m∠B = 6*20 - 28 = 120 - 28 = 92°m∠C = 2*20 = 40°[Sum of the angles of any triangle is 180°]
↦m∠A + m∠B + m∠C = 180°
The given values and solve for x :
[tex]↦48 + 6x - 28 + 2x = 180°[/tex]
[tex]↦8x + 20 = 180°[/tex]
[tex]↦8x = 160°[/tex]
[tex]↦x = 20°[/tex]
Lets , Find the missing angles:
[tex]↦ m∠B = 6×20 -28 = 120-28 = 92°[/tex]
[tex]↦ m∠C = 2×20 = 40°[/tex]
Answer :- [tex]\small\bold\red{x = 20°, m∠B = 92°, m∠C = 40°}[/tex]

Step-by-step explanation:
Use the graph or table to find the equation that represents the relationship.
to get the equation of any straight line we only need two points off of it.
1st one
well, we have four points on the table, let's use a couple from it hmmm say (10 , -25) and (13 , -34)
[tex](\stackrel{x_1}{10}~,~\stackrel{y_1}{-25})\qquad (\stackrel{x_2}{13}~,~\stackrel{y_2}{-34}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-34}-\stackrel{y1}{(-25)}}}{\underset{run} {\underset{x_2}{13}-\underset{x_1}{10}}}\implies \cfrac{-34+25}{3}\implies \cfrac{-9}{3}\implies -3[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-25)}=\stackrel{m}{-3}(x-\stackrel{x_1}{10}) \\\\\\ y+25=-3x+30\implies y=-3x+5[/tex]
4th one
well, from the picture itself we already have a couple of points we can use hmmm (0 , -4) and (5 , 0)
[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{0}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{0}-\stackrel{y1}{(-4)}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{0}}}\implies \cfrac{0+4}{5}\implies \cfrac{4}{5}[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-4)}=\stackrel{m}{\cfrac{4}{5}}(x-\stackrel{x_1}{0}) \\\\\\ y+4=\cfrac{4}{5}x\implies y=\cfrac{4}{5}x-4[/tex]
Step-by-step explanation:
(5,-10)(10,-25) is
y=-3x+5
(-7,-11)(7,3) is
y= x -4
(0.5,0)(0,-1) is
y = 2x-1

Thomas goes to summer camp every year if his parents drive 155 miles to Camp to drop him off and then go back to pick him up in two weeks, How many miles will they have traveled?
Answer:
620 miles
Step-by-step explanation:
knowing that if his parents drive 155 miles to camp and then go back and then pick him up in two weeks.
Thus ,Times they drove back and forth is:
Drive to camp
Go back home
Pick him up
Drive back home
Hence, that a total of 4.
Since it 155 miles to camp then it the same going back home and pick him up and then drive back home
Therefore,
155 × 4 = 620
As a result, they would have to traveled 620 miles.

2) The Richter magnitude M is given by the model LaTeX: M=\log\left(\frac{I}{I_0}\right)\:\:where LaTeX: I is the intensity of the earthquake in 100 km from the epicenter and LaTeX: I_0 is the smallest seismic activity that can be measured or LaTeX: M=\log\left(Intensity\right)\:\:. A recent earthquake measured 6.2 on the Richter scale. How many times more intense was this earthquake than an earthquake that measured 5.3 on the Richter scale?
7.9 times more intense
0.9 times more intense
1.5 times more intense
6.3 times more intense
The intensity of the earthquake is an illustration of functions
The earthquake's magnitude is 7.88The earthquake is 0.9 times more than the earthquake that measured 5.3How to determine the magnitudeThe function is given as:
[tex]M=0.67 \log(0.37E)+1.46[/tex]
When the earthquake releases 10,500,000,000, we have:
[tex]M=0.67 \log(0.37*10500000000)+1.46[/tex]
Evaluate
[tex]M=7.8848919855[/tex]
Approximate
[tex]M=7.88[/tex]
Hence, the earthquake's magnitude is 7.88
Also, we have:
Earthquake 1 = 6.2
Earthquake 2 = 5.3
Calculate the difference (d)
[tex]d = 6.2-5.3[/tex]
[tex]d = 0.9[/tex]
Hence, the earthquake is 0.9 times more than the earthquake that measured 5.3

P(teacher and chooses play) is an example of independent events.
What is Independent events?
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B.
According to questions, the activity preference of teachers and librarians
are:
For Teachers:

Answer:
22) a. Supplemental angles
b. 43.5 degrees and 136.5 degrees
Step-by-step explanation:
22) a) If 2 angles are on a straight line then they are supplemental angles. Supplemental angles add up to 180 degrees
b) (x+1) + (3x+9) = 180
Combine like terms
4x + 10 = 180
4x = 170
divide both sides by 4
x = 42.5
so the 2 angles are 1) 42.5 + 1 = 43.5 and 2) 3(42.5) + 9= 136.5
