OK so first the box and whisper box the way I did it was I drew a line and labeled the numbers 41.2, 44.8, 53.9, 64.5, 73.9, 82.7, 87.2, 85.1, 78.2, 67, 56.3, and 46 but put them I. order on the line. now you only have to put a dot for b,c,d. the median is 60.4 because the amount of numbers is positive because its 12 so you do the two middle numbers which is 56.3 and 64.5. you add those two together and divide by two which will give you 60.4. for c I think the answer are below the median and d are above the median and then e could be its warmer in the summer time and colder: n the winter or something like that

Step-by-step explanation:

Suppose we have given temperature are: 42,46,54,65,75,85,29,31,39,48,57,67,89,87,80,68,58,46,73,71,64,52,43,33.

a)- So, the Box plot of this data is drawn in graph.

b)- Median = 57.50

We have 24 temperatures. For finding the Median: Firstly we arrange data in ascending or descending order, after that we take the middle value of data, here we have two values 57 & 58 (Since the length of data is even number). After that, we find the average of both number which is 57.50 (These is also clear by Box plot, the middle line drawn in the box is median)

c)- 71.50 It can be found by the Third Quartile, It can be found manually or by box plot ( the top endpoint of the box represents the third quartile).

d)- 45.25 It can be found by First Quartile, It can be found manually or by box plot ( the bottom endpoint of the box represents the first quartile).

e)- The conclusion we get is:

The lowest temperature in Maryland is 29 (it is the lowest point of whisker).

The highest temperature in Maryland is 89 (it is the highest point of whisker).

The average temperature in Maryland is 58.42

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Nat2105 [25]

Answer:

Step-by-step explanation:

First choose two points on the line,

Let the points are A and B.

From point A to B we are moving downwards by (5 - 1 = 4 units)

Therefore, Rise = -4

Horizontal distance between A and B = 2 units

Therefore, Run = 2

Since, slope of a line = \frac{\text{Rise}}{\text{Run}}

Slope = \frac{-4}{2}

          = -2

K<br> M<br> N<br> L <br>Radius:13<br> Diameter:26 cm <br>Circumference:?<br> Area:?
Step2247 [10]

Answer:

Given radius (R) = 13

Diameter =  2R =  26

Circumference =  2πR

=  26π

=  81.681408993335

Area =  πR2

=  169π

=  530.92915845668

Step-by-step explanation:

While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.

John and Beth plan to visit a bookstore. Based on their previous visits to this bookstore, the probability distributions for the
lora16 [44]

Answer:

D) 0.1250

Step-by-step explanation:

Let P(J) = Probability of John to purchase 0 books

Let P(B) = Probability of Beth to purchase 0 books

P(J∩B) = Probability that both john and Beth will purchase 0 books .ie. a total of 0 books is purchased.

Since the decisions to purchase books are two independents events,

P(J∩B) = P(J) * P(B)

P(J) = 0.5

P(B) = 0.25

P(J∩B) = 0.5 * 0.25

P(J∩B) = 0.125
