Answer: 45% or 9/20
Step-by-step explanation:
50% is half and 33% is 1/3. 45% is less than 50% and greater than 33% and 9/20 is the simplified fraction form of 45%.
12, 13, 14, 15, 21, 24, 25, 26, 27, 29, 32, 32, 38, 41, 47. Make a box-and-whisker plot for the data. What is the 5 point summary for this box and whisker plot?
Answer:
Hence the five point summary is:
i) Minimum = 12
ii) Maximum = 47
iii) Median = 26
iv) First quartile = 15
v) Third quartile = 32
Step-by-step explanation:
The five point summary of a box and whisker plot is the minimum, maximum, median, first quartile and third quartile.
Given the number 12, 13, 14, 15, 21, 24, 25, 26, 27, 29, 32, 32, 38, 41, 47.
The median is the middle number = 26
The first quartile is the median of the numbers to the left of the median. Hence the first quartile is the median of 12, 13, 14, 15, 21, 24, 25
First quartile = 15
The third quartile is the median of the numbers to the right of the median. Hence the third quartile is the median of 27, 29, 32, 32, 38, 41, 47.
Third quartile = 32
The minimum is the lowest number = 12
The maximum is the largest number = 47
The box and whisker plot is attached
Hence the five point summary is:
i) Minimum = 12
ii) Maximum = 47
iii) Median = 26
iv) First quartile = 15
v) Third quartile = 32

Find the length of the arc
A.8 pie ft
B.32 pie ft
C.64 pie ft
D. 361 pie/ 12 ft
======================================================
Explanation:
The perimeter around the circle is known as the circumference
The full circumference of a circle with radius r is
C = 2*pi*r
In this case, r = 16 is the radius, so,
C = 2*pi*r
C = 2*pi*16
C = 2*16*pi
C = 32pi
is the full distance around the circle. But we only want 90/360 = 1/4 of that total distance. So take 1/4 of 32pi to get
(1/4)*32pi = (1/4*32)pi = 8pi
The arc length is exactly 8pi feet long
Approximately this is about 25.13274 feet
The length of the arc is exactly 8π feet long.
To find the length of the arc.
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”.The perimeter around the circle is known as the circumference.
Given that:
Ф=90°
r=16 feet
The perimeter around the circle is known as the circumference.
The circumference of a circle with radius r is
C = 2*π*r
C = 2*π*16
C = 2*16*π
C = 32π
But we only want 90°/360° = 1/4 of that total distance. So multiply 1/4 to 32π to get.
=(1/4)*32π
= (1/4*32)π
= 8π
Therefore, the length of the arc is exactly 8π feet long.

What might cause a theory to change over time
Answer:
Accepted theories may be modified or overturned as new evidence and perspective emerges. Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more. The process of theory change may take time and involve controversy, but eventually the scientific explanation that is more accurate will be accepted.
The discovery of new evidence because it's the only one that would give proof and science relies on proof.

Answer:
11. 9. 4.
Step-by-step explanation:
Since BD bisects ABC, angle ABD = angle CBD.
(13x - 56) = (7x + 10)
6x = 66
x = 11.
Again for the next question BD bisects ABC.
(x + 15) = (4x - 12)
3x = 27
x = 9.
For the last question,
(9x + 9) = (12x - 3)
3x = 12

e) 2,100 cm
f) 10,000 cm
g) 10,500 cm
h) 100 cm
Step-by-step explanation:
When you go to convert centimeters into meters, you divide the number of centimeters by 100. Once divided, that number is how many meters it is. Ex. There are 652 cm and you need to find out how many meters there are. Divide 652 by 100 (652/100) and that equals 6.52 m
When you go to convert meters into centimeters, multiple the number of meters by 100. Ex. There’s 4 m of rope and you want to know the length in centimeters. Multiply 4 by 100 (4x100) and you should get 400 cm.
6x + 3 (2x) - 7 - 2³ Please include th steps to solving it.
Answer:
24x-15
Step-by-step explanation:
Let's do this together with a step-by-step explanation!
First we need to make sure we remember that there are appropriate ways on how to solve these. LIKE PEMDAS.
6x + 3 (2x) - 7 - 2³
Let's multiply the 3 and 2x together.
6x + 6x - 7 - 2³
Now let's do the exponent
6x + 6x - 7 - 8
Now let's add everything together! But remember only common variables can be added together.
24x - 15 is the answer.
You can no longer break anything down.
I really hope this helped you!
Answer:
12x - 15
Step-by-step explanation:
so you would have to do the order of operations. so your exponent would be first. so 2×2×2=8.
6x + 3 (2x) -7 + 8
Now you can look at your parentacese which is (2x) so you need to do 3(2x) which gets you 6x.
6x + 6x -7 + 8
So you need to combine like terms.
so starting with the x
6x + 6x = 12x
Now your equation looks like this
12x + -7 +8
now you need to add like terms. (numbers)
-7 -8
so your answer is
12x -15
5 Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is
equal to 1-2-(-7) units.
Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate
plane is equal to 2 + 9 units.
Is either Laura or Ryan correct? Explain.
Answer:
Ryan is correct.
Step-by-step explanation:
Laura says that the distance between (4, -2) and (4, -7) in the coordinate plane is equal to 1-2-(-7) units.
Here, x-coordinates are same, so the distance between these points is the difference between y-coordinates.
Distance between (4, -2) and (4, -7) = -2-(-7)
= -2+7
= 5 units.
So, Laura is incorrect.
Ryan says that the distance between the points (2, 3) and (-9,3) in the coordinate plane is equal to 2 + 9 units.
Here, y-coordinates are same, so the distance between these points is the difference between x-coordinates.
Distance between (2, 3) and (-9,3) = 2-(-9)
= 2+9
= 11 units.
Therefore, Ryan is correct.
On a vertical line segment, point A is located at 50. Point B is located at 104. Point P is a point that divides segment AB in a ratio of 1:5 from A to B. Where is point P located?
Answer:
Step-by-step explanation:
Let the initial point on the line segment be O. If point A is located at 50 and point B is located at 104, then OA = 50 and OB = 104. Using the vector notation;
AO+OB = AB
(-OA)+OB = AB
-50+104 = AB
AB = 54
If point P divides the segment AB in a ratio 1:5, them AP:PB = 1:5
AP = 54/6
AP = 9
PB = 54-9
PB = 45
Hence the point P is located at 9 units from A and 45 units from B

The left and right page numbers of an open book are two consecutive integers whose sum is 229
Answer:
114, and 115
Step-by-step explanation:
114+115 = 229
Answer:
114 and 115
Step-by-step explanation:
Let's say the pages are p
so
Left page = p
Right page = p+1
p(p+1) = 229
2p+ 1 = 229 we want to know what p is so isolate the variable:
-1 -1
2p=228 Divide:
p=114
The pages are 114 and 115
Check: 114+115 = 229
Hope this helps :)
