Answer:
A. The number of women and the number of men included in the data
Step-by-step explanation:
The boxplot is a useful way to display data. It represents the distribution of data in a five-number summary. These five numbers include the minimum, first quartile, median, third quartile, and maximum. Respectfully, each line on the graph, from left to right, represents one of these numbers. However, because the graph only shows the distribution of data, it does not include the sample size.
Find the height of a rectangular prism with a 3 in by 4 in base and a volume of 20 cubic inches
Answer:
1 2/3 inches.
Step-by-step explanation:
Volume = area of the base * height so:
20 = 3*4 * h
h = 20/12
h = 1 2/3 inches.
Student Council members are designing a large poster that will tell people who each member is and what position each person holds. Each member gets a triangle piece of paper to decorate, then all the pieces will be fitted together to form the final display. The triangles are identical and fit together to form a regular polygon. It will look similar to the shape below:
A) If there are 8 council members, what type of polygon will be formed?
B) To achieve this shape, what type of triangles will the individual pieces be? What will be the measures of each of the three angles in each of the triangles?
C) What will be the sum of the measures of the internal angles of the final shape?
D) Redo parts (b) and (c) if the Council decides to include triangles for the two staff advisors, assuming the poster will still form a regular polygon, but now with 10 triangles.
A) With 8 council members, the polygon formed with the triangles will be an octagon.
A polygon formed with a set of isosceles triangles will have as many sides as triangles you are using. An octagon is a geometric figure that has 8 equal sides to it.The final shape should look just like the one you posted with your question.
B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 45°, 67.5° and 67.5°.
An isosceles triangle is the one that has two sides of the same length and one side with a different length.We need two sides of the triangles to be the same. The base of the triangle's length will depend on the number of triangles we are using to form the final polygon.
The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:
[tex]\frac{360^{o}}{8}=45^{o}[/tex]
The other two angles should measure the same, so we can find them by subtracting the 45° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.
180°-45°=135°
[tex]\frac{135^{o}}{2}=67.5^{o}[/tex]
C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:
45°+45°+45°+45°+45°+45°+45°+45°=360°
D)
D.B) The individual pieces should be isosceles triangles. The three angles of each triangle should measure 36°, 72° and 72°.
The number of triangles will define the angle between the two sides of equal length. You can find this by dividing 360° into the number of triangles:
[tex]\frac{360^{o}}{10}=36^{o}[/tex]
The other two angles should measure the same, so we can find them by subtracting the 36° from 180° (which is what we get when adding the three angles of any triangle) and then dividing the answer into 2.
180°-36°=144°
[tex]\frac{144^{o}}{2}=72^{o}[/tex]
C) The sum of the measures of the internal angles of the final shape should add up to 360°, that way we can guarantee that the figure is closed:
36°+36°+36°+36°+36°+36°+36°+36°+36°+36°=360°

(a)
Let the exponential equation will be:
⇒ [tex]P(t) = P_o e^{Kt}[/tex]

You are riding your bike. At 8:00am you have ridden your bike 23 miles. By 9:00pm you have ridden 179 miles. Find the rate of change in miles per hour. If needed, round your answer to the nearest whole number.
Answer:
12 miles/hour
Step-by-step explanation:
8am to 9pm = 13 hours
in that time we were driving 179-23 = 156 miles.
so, our speed was 156 miles / 13 hours.
now simplify it to our standard miles/hour format :
156/13 = 12

Answer:
108 degrees
Step-by-step explanation:
an arithmetic progression means that there is a constant inbetween all of the angles. Since the smallest angle is 12 degrees, ( i just guessed and checked) and came up with the angles :
12, 60, 108
these have a constant of 48
Answer:
108°
Step-by-step explanation:
Since the angles are in arithmetic progression , then the angles are
a + a + d + a + 2d
a is the first term and d the common difference
Sum the angles and equate to 180 with a = 12
a + a + d + a + 2d = 180
12 + 12 + d + 12 + 2d = 180 , that is
36 + 3d = 180 ( subtract 36 from both sides )
3d = 144 ( divide both sides by 3 )
d = 48
Then the largest angle is
a + 2d = 12 + 2(48) = 12 + 96 = 108°

Identify the equation of the circle that has its center at (9, 12) and passes through the origin.
Answer:
(x-9)^2 +(y-12)^2 = 225
Step-by-step explanation:
First find the length of the radius
If is the distance from the center to the point
d = sqrt( (x2-x1)^2 + (y2-y1)^2 )
= sqrt( (0-9)^2 + (0-12)^2)
= sqrt ( 81+144)
= sqrt(225)
= 15
The equation for a circle is
( x-h) ^2+ (y-k)^2 = r^2
(x-9)^2 +(y-12)^2 = 15^2
(x-9)^2 +(y-12)^2 = 225
A building in the shape of a pentagon is regular and has 50 feet long walls. What interior angles are formed when two of the walls meet?
A. 72
B. 90
C. 900
D. 108
Answer:
[tex]\text{D. }108^{\circ}[/tex]
Step-by-step explanation:
The sum of the interior angles of a polygon with [tex]n[/tex] sides is given by [tex]180(n-2)[/tex].
A pentagon is a shape with 5 sides and 5 angles. Therefore, the sum of its interior angles is equal to:
[tex]180(5-2),\\180\cdot 3=540^{\circ}[/tex]
Regular polygons can be defined as polygons with equal side lengths and angles. Therefore, to find the measure of each interior angle of a regular polygon, divide the sum of the interior angles (540 degrees) by the number of angles the polygon has (5 sides).
Therefore, each interior angle in a regular polygon has a measure of:
[tex]\frac{540}{5}=\boxed{108^{\circ}}[/tex]
Each interior angle in a regular polygon has a measure of is 108°. Therefore, option D is the correct answer.
What is the formula to find the number of sides with interior angle?We can find the number of sides in a polygon using the value of interior angle. Interior angle = 180°(n-2)/n, where n is the number of sides of the polygon.
The sum of the interior angles of a polygon with n sides is given by 180(n-2).
A pentagon is a shape with 5 sides and 5 angles. Therefore, the sum of its interior angles is equal to:
180(5-2) =540°
Therefore, option D is the correct answer.

Answer:
Step-by-step explanation:
I'll get you the answer. You pick it from what you are given.
The slope of the perpendicular is m1 * m2 = - 1
m1 = 3
m2 = -1 / m1
m2 = -1 / 3
So far what you have is
y = (-1/3) x + b
Use the point go get b
x = -1
y = - 3
y = (-1/3) *x + b
-3 = (-1/3)*-1 + b
-3 = 1/3 + b
-3 - 1/3 = b
b = -3.33333 or
b = -3 1/3
b = -10/3
So the answer is
y = (- 1/3) x - 10/3 or
y = (-1 / 3)x - 3.3333 or
y = (-1/3 )x - (3 1/3)

A house owner wishes to cover their roof with solar panels. Each solar panel is of the following size.
->The roof section is rectangular 7.2 m by 4.4 m.
->Each solar panel measures 1400 mm by 850 mm.
There needs to be at least a 30 cm gap left at each edge of the roof section. The house owner thinks he can have at least 15 solar panels fitted to the roof section.
Can u agree? If yes, show the working. (Hint: He can rotate the solar panel)
Answer:
Yes
Step-by-step explanation:
The roof is Rectangular :
Dimension of roof section : 7.2 m by 4.4 m
Area of roof = length * width
Area of roof = 7.2 * 4.4 = 31.68 m²
Dimension of solar panels = 1400 mm by 850 mm
Converting to m:
1000mm = 1 m
1400/1000 by 850/1000 = 1.4 m by 0.85 m
Area each solar panel = 1.4 * 0.85 = 1.19 m²
Gap left at each edge :
30cm gap about the 4 edges gives a square with side length 30cm:
30cm = 30/100 = 0.3m
Area of gap left = 0.3² = 0.09 m²
Total area that can be covered = (31.68 - 0.09) m² = 31.59 m²
Maximum number of panels that can be placed on roof section :
Total area that can be covered / area of panel
31.59 m² / 1.19 m²
= 26.54 panels
An acute angle of a right triangle measures 30°, and the length of the triangle's hypotenuse is 10 ft. Find the missing angle measure and side lengths.
Answer:
missing angle <60 and side lengths 5, 5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
we understand from the given information that the triangle in question is a special right triangle
and since this is a special triangle the side lengths follows :
the side length that sees <90 is represented by 2x
the side length that sees <60 is represented by x[tex]\sqrt{3}[/tex]
and the side length that sees <30 is represented by x
2x = 10 so x = 5 and x[tex]\sqrt{3}[/tex] = 5[tex]\sqrt{3}[/tex]
