When all the values in a data set are written in order from least to greatest, the value that is in the middle, with an equal number of values below it and equal number of values above it is called the median.
Also, the median is at the 50th percentile, hence why there are an equal number of values above and below it.
Hope this helps!

x= -5 -4 -3 -2 -1 0
f(x)= 0 -2 6 7 -5 3
What is f(f(-1)?
Answer:
f(f(-1)) = 0
Step-by-step explanation:
Ok I'm assuming that's supposed to be a chart of some kind. So first, you have to find what f(-1) is according to the chart.
According to the chart, if x = -1, then f(-1) is -5
Now comes the next part of the equation. So you need to find f(-5)
-5 was already founded by f(-1) bc it's first in the parantheses.
f(-1) is -5
so we need to find f(-5)
According to the chart f(-5) is 0
So ur final answer is gonna be 0

Find the length of RX. PLEASE HELP ASAP!
A.7.96
B.76.11
C.76.53
Answer:
B
Step-by-step explanation:
We want to find RX.
Note that RX is adjacent to ∠X and we also know the side opposite to ∠X.
Thus, we can use the tangent ratio. Recall that:
[tex]\displaystyle \tan\theta = \frac{\text{opposite}}{\text{adjacent}}[/tex]
Substitute:
[tex]\displaystyle \tan6^\circ = \frac{8}{RX}[/tex]
Take the reciprocal of both sides:
[tex]\displaystyle \frac{1}{\tan6^\circ}= \frac{RX}{8}[/tex]
Multiply both sides by 8:
[tex]\displaystyle RX = \frac{8}{\tan6^\circ}[/tex]
Use a calculator (make sure you're in Degrees mode!):
[tex]\displaystyle RX\approx 76.1149[/tex]
Hence, our answer is B.

Answer: 29152332 ≡ 0 (mod 3)
Step-by-step explanation:
In modular arithmetic, there is the form a ≡ b (mod m) where b is the remainder.
To solve this problem, we want to divide 29152332 by 3 and find the remainder.
29152332 ÷ 3 = 9717444
Since we get an integer with no remainder, we know the answer is 29152332 ≡ 0 (mod 3).
6. The right triangles ABC and DEF are
similar. The hypotenuse of ABC
measures 28 cm and the hypotenuse
of DEF measures 7 cm. If one of the
legs of ABC measures 16 cm, what
does the corresponding leg of DEF
measure?
F 1 cm
H 12 cm
G 4 cm
J 64 cm
Answer:
G 4 cm
Step-by-step explanation:
28/7 = 4, so the scale factor is 4. Therefore, if AC is 16, and triangle ABC is the bigger triangle, then divide it by 4 to get 4 cm for the smaller triangle DEF.
Find the lettered angles in each of the following.
( where a point o is given , it is the centre of the circle) .
t=46°
u=134°
v=23°
w=23°
Answer:
Solution given;
v=w [base angle of triangle]
<SPQ+<SRQ=180°[sum of opposite angle of a cyclic quadrilateral is 180°]
81+v+53+w=180°
134°+v+v=180°
2v=180°-134°
v=46/2
v=23°
w=v=23°
In triangle ∆ PQR
v+w+u=180°[sum of interior angle of a triangle]
23+23+u=180°
u=180°-46°
u=134°
again
In triangle ∆ PSR
t+81+53=180°
t=180°-134°
t=46°
Answer:
t and u are supplementary as opposite angles of a cyclic quadrilateral.
t = 180 - (81 + 53) = 46u = 180 - t = 180 - 46 = 134v and w are equal as opposite angles to equal sides.
v = w = 1/2(180 - u) = 1/2(180 - 134) = 23Evaluate the expression 4 + 9(3 + 11) - 15 2 using order of operations. the two is a exponet
Answer:
-95
Step-by-step explanation:
4+9(3+11)-15²
So, the order of operations is PEMDAS. The first thing is "P" for Parenthesis, so you would do whatever is in the parenthesis first.
3+11= 14
Now, the expression is 4 + 9 (14) - 15²
The next letter is "E" for Exponents. so the 15² has an exponent, so you do 15 x 15.
4+9(14)-225
Next is "M" for Multiplication. A number next to a parenthesis can mean multiplication as well. So, you do 9 × 14 = 126
Now, it's 4 + 126 - 225
Since there is only addition and subtraction left, you go left to right.
4 + 126 = 130
130 - 225 = -95
Hope this helps !!

suppose you roll to standard number cubes. let event a be rolling a 4 on the first die and let event b be rolling a 3 on the second die. are a and b independent events? are a and b mutually exclusive events. explain.
Answer:
The events are independent and are not mutually exclusive.
Step-by-step explanation:
Two events A and B are independent if the outcome of each of them does not affect the outcome of the other.
And two events are mutually exclusive if these can't occur at the same time.
Here the events are:
a = rolling a 4 on the first die
b = rolling a 3 on the second die.
Becuase, these are number cubes, we know that the outcome of one die has no impact in the outcome of the other die.
And because each outcome is on a different die, we can conclude that these events are independent.
(rolling a 4 in the first die does not change the probability of getting a 3 when we roll the second die).
Now, the events are mutually exclusive?
No, we can roll both dices and get a 3 in the first one and a 4 in the second one, so these events can happen in the same time.
Answer:
YES.
Step-by-step explanation:
The event rolling a number '4' and the event rolling a number '3' are mutually exclusive events because both of them cannot occur at the same time.

Select the correct answer.
The variable b varies directly as the square root of c. If b= 100 when c = 4, which equation can be used to find other combinations of band c?
Step-by-step explanation:
b varies as √c
b=kc
divide both side by c
k=b/c
k=100/4
k=25
the equation is:
25=b/c
Which of the following equations is NOT an example of inverse
variation?
1. f(x) = kx
11. f(x) = 2k/x
III. f(x) =-kx/z
Answer:
i and iii are not examples of inverse variation.
Step-by-step explanation:
Inverse variation between two variables, y and x, is written as:
y = k/x
This means that, as the absolute value of x increases, the absolute value of y decreases.
So we need to have the variable in the denominator.
Let's analyze the given options:
i) f(x) = k*x
Here, x is not in the denominator, this is a direct variation, so this is not an example of inverse variation.
ii) f(x) = 2k/x
Here we can see that the variable x is in the denominator, thus, this is an inverse variation.
iii) f(x) = -k*x/z
We can see that we have z in the denominator, but you can see that the variable is x, and x is in the numerator, thus, this is not an example of inverse variation.
We can conclude that:
f(x) = kx
and
f(x) =-kx/z
Are not examples of inverse variation.

Explain the connection between ∠2 and ∠B.
A triangle has angle measures 50 degrees, 65 degrees, and B. 2 lines extend from a horizontal line to form 3 angles. The angles are 50 degrees, 2, 65 degrees.
Answer:
∠2 ≅ ∠B
Step-by-step explanation:
Let the triangle be ABC,
Given that,
∠A = 50°
∠C = 65°
Using angle-sum property of the triangle,
∠A + ∠B + ∠C = 180°
50° + ∠B + 65° = 180°
∵ ∠B = 65° ...(i)
A.T.Q.
Two horizontal lines are extended making 3 angles. Two angles out of them are 50° and 65°.
Since the adjacent angles comprising a straight line is equals to 180°.
so,
∠2 + 50° + 65° = 180°
∠2 + 115° = 180°
∠2 = 180° - 115°
∵ ∠2 = 65° ...(ii)
Using (i) and (ii),
∠2 ≅ ∠B
Therefore, ∠2 and ∠B are congruent to one another.
Answer: Sample Response: The sum of the measures of the interior angles of a triangle is 180°. m∠B + 50 + 65 = 180, so m∠B = 65°. The sum of adjacent angles forming a straight line is also 180°. m∠2 + 50 + 65 =180, so m∠2 = 65°. The angles are congruent.
Step-by-step explanation: its the sample response
What is the length of the diagonal of the square shown below?
Answer:
option (B) is correct ......
Answer:
B. [tex]5\sqrt{2}[/tex]
Step-by-step explanation:
Hi there!
Notice how the diagonal splits the square into two right triangles. To find the length of the diagonal, we can use the Pythagorean theorem: [tex]a^2+b^2=c^2[/tex] where a and b are the legs of a right triangle and c is the hypotenuse, or the side opposite the right angle.
In this case, a is 5, b is 5 and we're trying to solve for c.
[tex]a^2+b^2=c^2[/tex]
Plug in the known values
[tex]5^2+5^2=c^2\\25+25=c^2\\50=c^2\\c=\sqrt{50}[/tex]
Simplify the radical
[tex]c=\sqrt{25*2} \\c=5\sqrt{2}[/tex]

Tan = opp / adj
Tan(60) = 27/x
x = 27/tan(60)
Answer:
x ≈ 5.4
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MN}{LM}[/tex] = [tex]\frac{9.3}{x}[/tex] ( multiply both sides by x )
x × tan60° = 9.3 ( divide both sides by tan60° )
x = [tex]\frac{9.3}{tan60}[/tex] ≈ 5.4 ( to the nearest tenth )

-7q+12r=3q-4r
-10q=-16r
r=(5/8)q
I think its correct
Answer:
r = 5/8(q)
Step-by-step explanation:
−7q + 12r = 3q − 4r
Add 4r to both sides:
−7q + 12r + 4r = 3q − 4r + 4r
−7q + 16r = 3q
Add 7q to both sides:
−7q + 16r + 7q = 3q + 7q
16r = 10q
Divide both sides by 16:
(16r)/16 = (10q)/16
r = 5/8(q)

Answer:
Yes, because 1 & 2 have to be the same
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
Supplementary means 180 degree.
∠1 + ∠3 = 180 ----> eq. 1
∠2 and ∠3 are linear pair angles which are also supplementary.
∠2 + ∠3 = 180 ----> eq. 2
∠3 = 180 - ∠1 ----> eq. 3
( from eq. 1 )
∠3 = 180 - ∠2 ----> eq. 4
( from eq. 2 )
From, eq. 3 and eq. 4,
180 - ∠1 = 180 - ∠2
Subtract 180 on both sides.
180 - 180 - ∠1 = 180 - 180 - ∠2
- ∠1 = - ∠2
Multiply - 1 on both sides,
∠1 = ∠2
Since,
∠1 = ∠2
Sides opposite to them also equal
So, AC = BC
If any two sides in a triangle is equal, then the triangle is an isosceles triangle.
Therefore,
Δ ABC is isosceles.
