Step-by-step explanation:
A stem-and-leaf plot is a detailed graphical presentation of quantitative data on special kind of table that promotes visualizing the individual numbers in the data with the number at the stem being the first digits of the numbers in the data set while the leaf represent the last digit of each number in the data set
Following the above rule, the data in the given stem-and-leaf plot are;
64, 67, 69, 79, 81, 81, 83, 83, 84, 86, 90, 91, 92, 95
Therefore, the set of data that could have been used to create the stem-and-leaf plot is the data set that has all the numbers in the given stem-and-leaf plot which is the data set;
64, 79, 95, 83, 81, 90, 67, 86, 91, 84, 81, 69, 83, 92.

Find the median and mean of the data set below:
21,0,36,30,13,32
Answer:
Mean: 22
Median: 25.2
Step-by-step explanation:
The mean is the sum of all the numbers in a set divided by the number of terms in a set.
The median is the middle value of the numbers when the numbers in a set are arranged from least to greatest. If there is two middle numbers, the median is the average of the two numbers.

Step-by-step explanation:
37+82=x(sum of two interior opposite angles is equal to the exterior angle formed)
119=x
therefore x=119 degree
x + 7y = 6x-(2/3)
Solve for x and y. You do not need to show your work
Answer:
[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]
[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]
Step-by-step explanation:
Solve for x:remove parentheses:
[tex] \displaystyle x + 7y = 6x - \frac{2}{3} [/tex]
move x to left hand side and y to right hand side and change its sign:
[tex] \displaystyle x - 6x = -7y - \frac{2}{3} [/tex]
simplify Substraction:
[tex] \displaystyle - 5x = \frac{-21y - 2}{3} [/tex]
divide both sides by -5:
[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]
Solve for y:move x to the right hand side and change its sign:
[tex] \displaystyle 7y = 6x - x- \frac{2}{3} [/tex]
simplify Substraction:
[tex] \displaystyle 7y =5x- \frac{2}{3} [/tex]
simplify substraction:
[tex] \displaystyle 7y = \frac{15x - 2}{3} [/tex]
divide both sides by 7:
[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]
and we are done!

(01.02 MC)Which of the following correctly uses absolute value to show the distance between -50 and 12?
OT-50 - 12| = |-62] = -62 units
OT-50 + 12 = 1-38= 38 units
OT-50 + 12 = 1-38] = -38 units
OT-50 - 12| = |-62] = 62 units
Plz help
Answer: Choice D
|-50-12| = |-62| = 62 units
================================================================
Explanation:
Draw out a number line. Mark two points on it at A = -50 and B = 12
The expression |A-B| represents the distance between the two points. So that would be....
|A-B| = |-50-12| = |-62| = 62
Note that negative distance does not make sense. The smallest distance can get is 0. So the result of an absolute value problem is never negative.
-------------------
Slightly alternative method:
If you wanted, you could plot point C on the number like such that C is at 0.
The distance from A = -50 to C = 0 is exactly 50 units
From C = 0 to B = 12 is an additional 12 units
Therefore, the total distance is AC+CB = 50+12 = 62 units
-------------------
Side note: |A-B| is the same as |B-A|. The order of subtraction doesn't matter as long as you use absolute value. If absolute value wasn't there, then A-B is different from B-A.

Why is 3 x 1/10 less than 3 x 10?
Answer:
The value of 1 tenth is less than the value of 1 ten.
Step-by-step explanation:
Answer:
Because 3 x 1/10 = 3/10
whereas 3 x 10 = 30
and 3/10 < 30
Also b/c 1/10 < 10 and they are multiplied by the same value (3)
Step-by-step explanation:
The table shows the total profits earned from magazine sales.

O A.) y = 24x
O B.) y = 10x + 28
O C.) y = 14x + 20

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

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.
Step-by-step explanation:
A boat leaves the dock and travels 9 miles due south, then 12 miles due west.
How far is the boat from the dock?
Dock
9 mi
Boat
12 mi
A. 15 mi
B. 21 mi
A boat leaves the dock and travels 9 miles due south, then 12 miles due west. Hence, the length of the boat from the dock will be 15 miles.
What is Pythagoras's Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
A boat leaves the dock and travels 9 miles due south, then 12 miles due west.
Let x be the length of the boat from the dock.
From the Pythagoras' theorem
[tex]|x|^2 = |12|^2 + |9|^2 \\\\x^2 = 144 + 81\\\\x^2 = 225\\\\x = \sqrt{225} \\\\x = 15[/tex]
Hence, the length of the boat from the dock will be 15 miles.
