Determine the mode
Though, not necessary; it is a good practice to order the given data either in ascending or descending order.
In ascending order, the ordered data are:
[tex]0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11[/tex]
Mode implies that: the data that has the highest number of occurrence.
In the given data, each data has a frequency of 1.
Hence, the mode is:
[tex]0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11[/tex]

b) solve for n
when
d=20
Answers
Answer:
a) we get value of n: n=10.7 or n=1.2 when d=30
b) we get value of n: n=9.6 or n=2.3 when d=20
Step-by-step explanation:
a) solve for n When do= 30
Put d= 30 in the given equation:
[tex]d = n^2-12n + 43[/tex]
[tex]30=n^2-12n+43\\n^2-12n+43-30=0\\n^2-12n+13=0\\[/tex]
Now, we will find value of n by using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=1, b=-12 and c=13
[tex]n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\n=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(13)}}{2(1)}\\n=\frac{12\pm\sqrt{144-52}}{2}\\n=\frac{12\pm\sqrt{92}}{2}\\n=\frac{12\pm9.59}{2}\\n=\frac{12+9.59}{2} , n=\frac{12-9.59}{2}\\n=10.7 , n=1.2\\[/tex]
So, we get value of n: n=10.7 or n=1.2
b) solve for n when d=20
[tex]d=n^2-12n+43\\20=n^2-12n+43\\n^2-12n+43-20=0\\n^2-12n+23=0\\[/tex]
Now, we will find value of n by using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
We have a=1, b=-12 and c=23
[tex]n=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\n=\frac{-(-12)\pm\sqrt{(-12)^2-4(1)(23)}}{2(1)}\\n=\frac{12\pm\sqrt{144-92}}{2}\\n=\frac{12\pm\sqrt{52}}{2}\\n=\frac{12\pm7.21}{2}\\n=\frac{12+7.21}{2} , n=\frac{12-7.21}{2}\\n=9.6 , n=2.3\\[/tex]
So, we get value of n: n=9.6 or n=2.3

Answers
Answer:
x = 4Step-by-step explanation:
From the diagram, we can se that line l is parallel to m. This means that according to geometry, m<7 and m<9 are located on the same position on line n. Hence m<7 = m<9 (corresponding angle)
Given
m<7 = 9x+ 5
m<9 = x+37
Equaling both
9x + 5 = x+ 37
9x - x = 37-5
8x = 32
x = 32/8
x = 4
Hence the value of x is 4

The volume of the rectangular prism is V = 64 units³
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the rectangular prism be represented as V
Now , the height of the prism is H = 4 units
The length and width of the prism is 1 and 16 units respectively
So , the base area of the prism B = 16 units²
Now , Volume of Prism = B x h
On simplifying , we get
The volume of rectangular prism V = 16 x 4
The volume of rectangular prism V = 64 units³
Hence , the volume of the rectangular prism is 64 units³

For a shape to be reflected, it must be reflected across a line.
The true statement about the relationship between segments M, M' and the x-axis is that (c) they are perpendicular to each other
Given that:
Shape: rectangle LMNOReflection line: x-axisWhen the shape is reflected across the x-axis, we have the following perpendicular and congruent lines

The length of a rectangular piece of cardboard is 2 cm greater than its width. If the length and the width were each decreased by 1 cm, the area of the cardboard would be decreased by 27 cm². What are the dimensions of the original piece of cardboard?
Write and solve an equation to represent the problem.
Answers
9514 1404 393
Answer:
13 cm wide; 15 cm long
Step-by-step explanation:
Let w represent the original width. Then the original length is (w+2) and the original area is w(w+2). After the decrease, the width is (w-1) and the length is (w+1). The decreased area is (w-1)(w+1). The difference between these areas is 27, so we have ...
w(w+2) -(w-1)(w+1) = 27
w^2 +2w -(w^2 -1) = 27
2w +1 = 27
w = (27-1)/2 = 13
The original piece of cardboard was 13 cm wide and 15 cm long.
What is the relationship between the length of one leg and the length of the hypotenuse of an isosceles right triangles?
A) Leg = Hypotenuse ∙ √2
B) Hypotenuse = Leg ∙ √2
C) Leg ∙ Hypotenuse = √2
Answers
Answer:
B) Hypotenuse = Leg ∙ √2
Step-by-step explanation:
This is a well-known ratio in the 45-45-90 right triangle, but we can derive it.
An isosceles right triangle has two congruent legs forming the right angle and the hypotenuse opposite the right angle. The Pythagorean theorem works since it is a right angle.
Normally, the legs are a and b, and the hypotenuse is c, and we have
a^2 + b^2 = c^2
Here the legs are congruent, so we have a = b.
Substituting a for b, we have
a^2 + a^2 = c^2
2a^2 = c^2
c^2 = 2a^2
c = a√2

Anthony is 154 cm tall, his brother Gerry is 5/7 as tall as him. How tall is Gerry?
:D can someone please help me with these problems please
Answers
The correct answer is 110 cm
Explanation:
Fractions always include two values (one at the top and the other at the bottom) and they represent the proportion of something, for example, 1/2 of an apple means there is only half apple. Now, to calculate how much is 5/7 of 154 centimeters, simply divide the total number into the denominator (bottom number) and then multiply the result by the numerator (top number). This process is shown in detail below:
[tex]\frac{5}{7}[/tex] - 5 is the numerator and 7 is the denominator
5/7 of 154 cm
154 cm / 7 = 22
22 x 5 = 110 cm
