B -Domain: whole numbers only from 0 to 14. Range: whole numbers only from 0 to 85.
C -Domain: all numbers from 0 to 14. Range: whole numbers only from 0 to 85.
Step-by-step explanation:
Notes:
The domain represents all x-values.
The range represents all y-values.
Domain: Whole numbers to represent the graph.
Range: Whole numbers to represent points.
A and C are incorrect.
A has the incorrect domain and range.
C represents all whole numbers and all real numbers.
B is correct.
Why?
B represents the whole numbers for where the line has been for x (0 - 14).
B represents the whole numbers for where the lines have been at for y (0 - 85)
B represents that the graph has ended.

Answer:
B
Step-by-step explanation:
From inspection of the box plot:
Minimum value = 24Maximum value = 34Lower quartile [tex](Q_1)[/tex] = 27Upper quartile [tex](Q_3)[/tex] = 33Median [tex](Q_2)[/tex] = 31The median is the middle number in a sorted (ascending or descending) list of numbers. All the numbers in each data set. are sorted in ascending order. Data sets C and D have medians of 30, so we can discount them.
The maximum value on the box plot is 34. Therefore, we can discount option A, since its max value is 35.
Therefore, the answer is option B.
Futher checking with quartiles:
The lower quartile is the value at the first quarter. As there are 9 values per data set, the lower quartile will be the mean of the 2nd and 3rd values.
The upper quartile is the value which is three quarters of the way into the data set. As there are 9 values per data set, the upper lower quartile will be the mean of the 7th and 8th values.
Option B
lower quartile = (25 + 29)/2 = 27
upper quartile = (32 + 34)/2 = 33
This confirms that Option B is the final solution.

Answer:
[tex]x=\frac{1}{2}[/tex]
Step-by-step explanation:
equation of a circle: [tex](x - h)^2+(y-k)^2=r^2[/tex]
where (h, k) = center and r = radius
From inspection, we can see that the center of the circle = (0, 0)
and the radius = 1
[tex]\implies (x - 0)^2+(y-0)^2=1^2[/tex]
[tex]\implies x^2+y^2=1[/tex]
Substitute [tex]y=\frac{\sqrt{3}}{2}[/tex] into [tex]x^2+y^2=1[/tex] and solve for [tex]x[/tex]:
[tex]\implies x^2+(\frac{\sqrt{3}}{2})^2=1[/tex]
[tex]\implies x^2+\frac{3}{4}=1[/tex]
[tex]\implies x^2=\frac{1}{4}[/tex]
[tex]\implies x=\pm \sqrt{\frac{1}{4}}[/tex]
[tex]\implies x=\pm\frac{1}{2}[/tex]
As point P is in quadrant 1, [tex]x[/tex] is negative, so [tex]x=\frac{1}{2}[/tex]

a
triangle
The measure of the First angle of
is 25 degree less than the measure of the
Second angle. The measure of the third angle
of the triangle is triple the measure of the
second angle.
Alright, lets say the measure of the 3rd angle (the smallest one) is x degree, then measure of the 1st angle will be (x + 25) degree, and 2nd one: 3x degree. The sum of all the angles in any triangles is 180 degrees.
(x + 25) + 3x + x = 180
5x + 25 = 180 ---> 5x = 180 - 25 ---> 5x = 155 ---> x = 155/5 ---> x = 31o (third angle)
31 + 25 = 56o (first angle)
3 × 31 = 93o (second angle)
56 + 93 + 31 = 180

susan wants to cut a log into 12 pieces with equally spaced cuts. How many cuts are necessary?
Answer:
She needs to cut the log 11 times
Step-by-step explanation:
hope that helps!!!
There are 11 cuts are necessary for equally spaced cuts.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Susan wants to cut a log into 12 pieces with equally spaced cuts.
Hence, To cut 12 pieces with equally spaced cuts, number of cuts are,
⇒ 12 - 1
⇒ 11
Thus, There are 11 cuts are necessary for equally spaced cuts.

What is $25 at 14% off
Answer:
$21.50
Step-by-step explanation:
10% of $25 is $2.50
4% of $25 is (1% of 25)×4
4% of $25 = $0.25×4
4%=$1
10%+4%=14%
$2.50+$1=14%
$3.50=14%
$25-$3.50=£21.50
Check whether this is a quadratic equation or not ...
=>>>>> x²-2x = (-2)(3-x)
Answer:
yup it is ...
x²-2x = -6+2x
=> x²-4x +6
By expanding the equation, we can see that it is quadratic.
Is the equation quadratic?
A quadratic equation is any polynomial of degree 2.
Here we have:
x^2 - 2x = (-2)*(3 - x)
Expanding this we get:
x^2 - 2x = -6 + 2x
Moving all to the same side:
x^2 - 2x - 2x + 6 = 0
x^2 - 4x + 6 = 0
This is a polynomial of degree 2, so this is a quadratic equation.

2.5 times 1,760 in steps.
Answer:
2.5 times 1760 is 4400
Step-by-step explanation:
math lol
Answer:
. We assume, that the number 1760 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 1760 is 100%, so we can write it down as 1760=100%.
4. We know, that x is 2.5% of the output value, so we can write it down as x=2.5%.
5. Now we have two simple equations:
1) 1760=100%
2) x=2.5%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
1760/x=100%/2.5%
6. Now we just have to solve the simple
equation, and we will get the solution we are looking for.
7. Solution for what is 2.5% of 1760
1760/x=100/2.5
(1760/x)*x=(100/2.5)*x - we multiply both sides of the equation by x
1760=40*x - we divide both sides of the equation by (40) to get x
1760/40=x
44=x
x=44
