What is Box and Whisker plots?A box and whisker plot is defined as a graphical method of displaying variation in a set of data.
From the first figure, write all the values where dark point is drawn
53, 62, 80, 86, 89
The lower extreme is the smallest value, which is 53.The upper extreme is the highest value, which is 89.
The median will be the middle of data , which is 80The upper quartile is the median of the upper region and the lower quartile is the median of the lower region.The upper quartile is 86 and the lower quartile is 62.
Range of the data be,= Highest - Lowest
=89-53
=36
From the second figure, write all the values where dark point is drawn
56, 62, 74, 89, 96
The lower extreme is the smallest value, which is 56.The upper extreme is the highest value, which is 96.
The median will be the middle of data , which is 74.The upper quartile is the median of the upper region and the lower quartile is the median of the lower region.The upper quartile is 89 and the lower quartile is 62.
Range of the data be,= Highest - Lowest
=96-62
=34
From the above discussion,
The First class have less upper extreme value than the second class.The First class have less lower extreme value than the second class.The First class have greater median than the second class.The First class have less upper quartile than the second class.The First and second class have equal lower quartile.The First class have greater range than the second class.The comparision of the two classes on the basis of extremes, quartile, median, range is concluded above.

What is the measure of angle y in this figure?
Answer:
163
Step-by-step explanation:
Opposite degrees are equal in two lines. (Vertical Angles)
Answer:
y = 163°
Step-by-step explanation:
The measure of angle y is 163 ° because vertical angles are congruent and congruent angles have the same measure.
find the x- and y- intercepts of parabola y=5x^2-16x+10
Y-INTERCEPT
[tex]y = 5x^2 - 16x + 10[/tex]
The y-intercept is where the equation/curve/parabola cosses the y-axis.
The y-axis is where x = 0. (The x-axis is where y = 0)
To find the y-intercept:
[tex]\text{y-axis} \rightarrow \text{x = 0} \rightarrow y = 5(0)^2 -16(0) + 10 = 10[/tex]
The y-intercept must be at (0, 10)
X-INTERCEPT (ROOTS/SOLUTIONS)
[tex]y = 5x^2 - 16x + 10\\\text{make it equal 0}\\y = 0\\\therefore 5x^2 - 16x + 10 = 0[/tex]
We need to use the quadratic formula
The quadratic formula helps us find what values of [tex]x[/tex] make the equation = 0
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\frac{-(-16) + \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\\x = \frac{16 + \sqrt{256-200}}{10}\\x = \frac{16 + \sqrt{56}}{10}\\x = \frac{16 + 2\sqrt{14}}{10}\\x = \frac{8 + \sqrt{14}}{5}\\\\\\x=\frac{-(-16) - \sqrt{(-16)^2-4(5)(10)}}{2(5)}\\\text{doing the same thing...}\\\text{end up with...}\\x = \frac{8 - \sqrt{14}}{5}\\[/tex]
The x-intercepts are at:
[tex](\frac{8 + \sqrt{14}}{5}, 0)\\(\frac{8 - \sqrt{14}}{5}, 0)[/tex]

Let's solve ~
Assume the number to be x, and let's proceed as per the given information :
[tex]\qquad \tt \dashrightarrow \: \dfrac{20}{100} \times x = 6 [/tex]
[tex]\qquad \tt \dashrightarrow \: \dfrac{x}{5} = 6[/tex]

So, the correct choice is C
20% of a number= 6.
to find:the unknown number.
solution:let the unknown be x.
[tex]20\% \times x = 6[/tex]
[tex] \frac{20}{100} = 6[/tex]
[tex]x = 6 \times \frac{100}{20} [/tex]

Answer:
A. How many vehicles do Boston residents have per household?
Step-by-step explanation:
A statistical question is that question, which is answered by collecting variable data. For example - “How old are the students in your neighborhood?”
So, here the question that is not statistical is How many vehicles do Boston residents have per household? As its answer can be 1 or 2 at maximum.
Whereas;
B. How much money do Boston residents spend on transportation every day? This is statistical as you need to conduct survey for this to collect data.
C. How many Boston residents use public transportation? This also needs survey to collect data and data will be variable.
D. How many times per month do Boston residents use public transportation? This is also statistical as you have to gather data from many people.
E. How long does it take for Boston residents to travel to work? This is also statistical as everyone will have a variable answer depending on the distance they travel.

A rectangular prism has a length of 4 in., a width of 5 in., and a height of 3 1/2in.
The prism is filled with cubes that have edge lengths of 1/2 in.
How many cubes are needed to fill the rectangular prism?
Step-by-step explanation:
it needs 4×2 = 8 cubes asking the length, 5×2 = 10 cubes along the width, and 3 1/2 × 2 = 7 cubes along the height.
so, altogether
8×10×7 = 560 cubes
A man drove his car at 80km per hr for 1 and a quarter hrs .He rested for 45mins and then covered 240km, at the same time. Calculate his average speed for the whole journey
Answer:
Probably 128 km/h, but maybe 98.5 km/h. See below.
Step-by-step explanation:
What does "at the same time" mean?
If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 1.25 hour = 2.5 hour
average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h
If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:
80 km in 1.25 hour
240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour
Total distance: 80 km + 240 km = 320 km
Total time: 1.25 hour + 2 hour = 3.25 hour
average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h
What is the perimeter of the woods, in miles? Round
you
answer to the nearest tenth.
The perimeter of the woods is 26 miles if each grid represents one mile in the figure.
What is the area of the rectangle?It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.
The formula for finding the area of a rectangle is given by:
Area of rectangle = length × width
We know the perimeter of the rectangle = 2(length + width)
As we can see closely in the figure the perimeter of the wood is actually a perimeter of a rectangle if we shift vertical and horizontal lines to make it a complete rectangle.
Let's suppose each grid is expressing one mile.
So the length of the rectangle = 9 miles
The width of the rectangle = 4 miles
The perimeter of the woods = 2(9+4) = 26 miles
Thus, the perimeter of the woods is 26 miles if each grid represents one mile in the figure.

A balloon rises to 100 feet in 4 minutes and 125 feet in 5 minutes. Write and solve an equation to find the distance the balloon rises in 8 minutes. Use d for distance and m for minutes.
Write the equation and the answer separated by a semi-colon. Included the unit in your answer.
For example, d = 5m; 35 feet
Answer:
See below
Step-by-step explanation:
100 ft in 4 min = 25 ft/min
125 feet in 5 min = 25 ft min
so the height is d = 25 * m d = height m = minutes
25* 8 = 200 feet

When fractions have a common denominator, you add them by adding their numerators and using that sum with the common denominator.
Here, you may be able to cancel a common factor from numerator and denominator to simplify the expression further.
[tex]\dfrac{4m-17}{m^2-16}+\dfrac{3m-11}{m^2-16}=\dfrac{4m-17+3m-11}{m^2-16}=\dfrac{7m-28}{m^2-16}\\\\=\dfrac{7(m-4)}{(m+4)(m-4)}=\boxed{\dfrac{7}{m+4}}[/tex]
