Otis is cutting a long piece of wood trim into smaller pieces for an art project. The line plot shows the length of the smaller pieces of wood. How many pieces of wood will be at least 1 2 foot in length?
Answer:
6
Step-by-step explanation:
From the line plot, the length of wood measuring atleast 1/2 in length include :
Piece with length 1/2 and pieces with length 2/3
Number of pieces with length 1/2 feets = 4
Number of pieces with length 2/3 feets = 2
Pieces with atleast 1/2 feet length = 4 + 2 = 6

Answer:
The Mean 14.5 and the Median is 15
Step-by-step explanation:
For the Mean you just add all the numbers up and divide on how many you have. And the Median the middle
Answer:
Below in bold.
Step-by-step explanation:
First arrange in ascending order:
5 8 9 11 13 15 16 17 17 18 22 23
Median = mean of the middle 2 values = (15+16)/2 = 15.5.
Mean = Sum of all the values / 12 = 174/12 = 14.5.
Interquartile range = upper quartile - lower quartile = 17 - 11 = 6.
Which of the following is likely to have the greatest variability? *
F. The cost of a piece of candy from a vending machine
G. The height of all the students at West Middle School
H. The age of all the students in the sixth grade
J. The number of days in a month
Answer:
G
Step-by-step explanation:
The most likely to have the greatest variability is,
⇒ The height of all students at West Middle school.
What is an expression?A Mathematical expression is defined as collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division
Now, We know that;
Greatest variability is large spectrum of possibilities.
Hence, We get;
The costs of candy from vending machine are going to be about the same price because they are all candy, so that does not vary much more.
And, The age of all the students in the sixth grade is going to be about the same because they are in the same grade.
Since, The number of days in a month is usually 31 or 30, so that also does not vary much.
This means, it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.
Thus, The most likely to have the greatest variability is,
⇒ The height of all the students at West Middle school

Two cards are drawn from a deck of 52 cards. What is the probability that the first card
drawn is a king and the second card drawn is a heart, given that the first card is
replaced? (Hint: A deck has 4 kings and 13 hearts)
Answer:
1) P(First card was a king) = 1/13 2.) 1/4
Step-by-step explanation:
1) P(First card was a king) = n(King)/n(Total) = 4/52 = 1/13
2. P(Heart)13/52 = 1/4
Answer:
1/52
Step by step explanation:
First, find the probability that the first card will be a King. Since there are 4 possible kings, and 52 cards, the probability is 4/52.
Then, find the probability that the second card will be a heart. "given that the first card is replaced" means that there are 13 possible hearts regardless of the suit of the first card. So 13/52 is the probability.
To find the probability of both occurrences, multiply them.
4/52 * 13/52 = 52/2704
52/2704 can be simplified to 1/52. So that is the probability that the first card will be a king and the second card will be a heart.
Toby and Ahmed are eating pizza. Toby eats 1/2 of the pizza and Ahmed eats 1/4 of the pizza. How much of the total pizza have they eaten? 1 point
Answer:they have eaten 3/4 of the total pizza
Step-by-step explanation:
Let the whole pizza =1whole
Amount eaten by Toby =1/2
Amount eaten by Ahmed =1/4
Total Amount eaten by both of them =1/2 +1/4 = 2+1/ 4=3/4
Therefore, they have eaten 3/4 of the total pizza
Drag and drop the numbers 1 - 9 into the empty
boxes to the right to create a right triangle with the largest area
possible (round to the nearest TENTH, if necessary).
Each number can only be used one time, and only one number
can be placed per empty box (there will be some unused
numbers).
Answer:
9 for the hypotenuse, [tex]\sqrt{64}[/tex] and [tex]\sqrt{25}[/tex] for the two legs
Step-by-step explanation:
For these types of problems, we need to make sure that the values of legs are as big as possible while keeping the hypotenuse larger than legs because otherwise, it won’t be a right triangle.
So for the hypotenuse, we have to put the largest number in this number bank because the hypotenuse has to be larger than both legs. So the hypotenuse will equal 9. The rest is simple. Get the numbers as large as possible. Since the hypotenuse must be larger than both legs, we cannot use sqrt(81) and sqrt(64) (that would’ve been sweet). So we have to use sqrt(64) and sqrt(25) because sqrt(49) and sqrt(36) are already taken since we can only use a number once.
I'm not an expert at this and I cannot guarentee that this is correct. But I hope that this helps.

Dialating means you are multiplying or dividing. Since 2 is positive you multiply everything by 2, usually it would be coordinates, like if it said dialate (2,4) by 6 we would get (12, 24), but I didn't really want to have to solve the equation for the coordinates so try the answer I wrote, if not I am so so so sorry but at least now you know what dialating means.

essay on kim jong un
Answer:
Step-by-step explanation:
From late 2010, Kim Jong-un was viewed as successor to the leadership of North Korea. Following the elder Kim's death in December 2011, state television announced him as the "Great Successor". Kim holds the titles of General Secretary of the Workers' Party of Korea,[7] Chairman of the Central Military Commission, and President of the State Affairs Commission. He is also a member of the Presidium of the Politburo of the Workers' Party of Korea, the highest decision-making body. In July 2012, Kim was promoted to the highest rank of Marshal in the Korean People's Army, consolidating his position as Supreme Commander of the Armed Forces. North Korean state media often refers to him as "the Marshal" or "Dear Respected Leader". He has promoted the policy of byungjin, similar to Kim Il-Sung's policy from the 1960s, referring to the simultaneous development of both the economy and the country's nuclear weapons program.
Triangle ABC has vertices A(-2,0), B(2,5), C(3, 1). The reflection of the image of triangle ABC is triangle A'B'C' with vertices A(-2,0), B12, -5), C73.
-1). What is a rule that describes the reflection?
Answer: Reflection about x-axis
Step-by-step explanation:
Given
Initially, vertices are [tex]A(-2,0), B(2,5),C(3,1)[/tex]
After reflection they become [tex]A(-2,0),B(2,-5),C(3,-1)[/tex]
It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.
For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).
So, here reflection is being done about the x-axis.

Pls answer this with a picture showing the correct box plot
Answer/Step-by-step explanation:
To find out the mistake of the student, let's find the min, max, median, Q1 and Q3, which make up the 5 important values that are represented in a box plot.
Given, {2, 3, 5, 6, 10, 14, 15},
Minimum value = 2
Median = middle data point = 6
Q1 = 3 (the middle value of the lower part of the data set before the median)
Q3 = 14 (middle value of the upper part of the data set after the median)
Maximum value = 15
If we examine the diagram the student created, you will observe that he plotted the median wrongly. The median, which is represented by the vertical line that divides the box, ought to be at 6 NOT 10.
See the attachment below for the correct box plot.

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
y = 75.2
By = 52
C y = 2
Dy = 152
Answer:
one board game cost 15 dollars
75/5=15
15y
y = number of board games and 15= the price of each board game
so to calculate any number of board games bought just input the number of board games bought for y in the expression 15y and you will get the price.
