Answer:
1.
Mean- AverageMedian- the middle number in a sorted, ascending or descendingMode- the most commonly observed value in a set of data2.
Using the example of- 1, 2, 2, 3, 3, 3, 4, 5, 6, 7
Mean- Average, (the sum of every value)/10(# of values)= 3.2
Median- 3 (even though there are 2 3s, but add them up and divide the sum by 2)
Mode- 3
3. Well... you could use these data to do science reports etc, ofc in the world of academics, you would need to use this kind of statistics terms a lot. In normal life, you might have to compare the price of similar products and see which is the best to purchase, seeing the value of the median of the entire set of data.

What is the missing Angle
Answer:
31°
Step-by-step explanation:
As there is a z shape: we can deduce that:
5x+12+x=180
So now we solve this to get x
6x=180-12
6x=168
x=168÷6
x=31

jk + 4m/2 Can somone explain this to me please
Answer:
Since J = 3, K = 6, and M = 12, the equation means:
(3 • 6) + (4 • 12 ÷ 2) = ???
Step-by-step explanation:
This is because when variables are next to each other and we know what they are equal to, it is the same as saying 3 • 6. So, when two variables are next to each other, they are being multiplied. Same with 4m/2. / can also mean division. And since 4 is next to m, the two are being multiplied. All together, the answer to this equation is 42. Hope this helped!
Answer:
(3*6) +((4*12)/2)
Step-by-step explanation:
j=3 k=6 M=12
two variables next to each other is multiplication
and use order of operations (PEMDAS)
42 is the answer

Answer:
Not completely sure about A but I know the rest!
Explanation:
a) burritos are the independent variable because it is labeled as x. X will always be the independent variable. The reason I am confused is because all throughout my learning I was told "time" will always be independent and it had always proved to be true. I would just go with burritos though.
b) linear function is y=0.75x, with 0.75 being the slope representing the amount of time taken to make x amount of burritos. I see you already did most of the work! You just have to remember that to find slope (or m), that you do change in y/change in x.
c) when graphing, draw a point at the origin, (0,0). Then count 0.75 units up, and move 1 unit to the right. Your line should be from left to right going "upward".
d) your answer for d is correct

Answer:
<5 is half of <3 (112/2=56)
<6 is the same as <3. I know this to be true because when the angle are like across from each other. Basically the number that are across from each other (hope that makes sense). <1 is the same as <8 and they are both half of <3 which is 56.

what are the four parts of mathematical system?
Answer:
Structure of Mathematical Systems Mathematics can be divided into four major areas- higher arithmetic, algebra, geometry, and analysis.
Answer:
Sorry I didn't get the answer option first
Step-by-step explanation:
higher arithmetic, algebra, geometry, and analysis.
Arithmetic: It is the oldest and the most elementary among other branches of mathematics. It deals with numbers and the basic operations- addition, subtraction, multiplication, and division, between them.
Algebra: It is a kind of arithmetic where we use unknown quantities along with numbers. These unknown quantities are represented by letters of the English alphabet such as X, Y, A, B, etc. or symbols. The use of letters helps us to generalize the formulas and rules and also helps you find the unknown missing values in the algebraic expressions and equations.
Geometry: It is the most practical branch of mathematics that deals with shapes and sizes of figures and their properties. The basic elements of geometry are points, lines, angles, surfaces and solids.
There are some other branches of mathematics that you would deal with in the higher classes.
Trigonometry: Derived from two Greek terms, i.e., trigon (means a triangle) and metron (means measurement), it is the study of relationships between angles and sides of triangles.
Analysis: It is the branch that deals with the study of the rate of change in different quantities. Calculus forms the base of analysis.

Javier walks up to a tank of water that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Javier first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
How many minutes before Javier arrived was the water tank completely full? Explain or show your reasoning.
Answer:1) Gallons per minute change is -2/3 gallons per minute since it decreases by 2 gallons in 3 minutes
2) we have 5 gallons and lose 2/3 gallons per minute
(2/3 gal/minute)(x minutes) = 5 gallons
x = 5(3/2) = 15/2 = 7.5 minutes to drain the other 5 gallons
3) There were 10 gallons when the tank is full
That is 3 gallons more than the 7 gals there when Jada arrived.
(2/3)(x) = 3
x = 3(3/2) = 9/2 = 4 1/2 minutes
The tank was full 4 1/2 minutes before Jada arrived.
can some help i cant figure this out
Answer:
240cm²
Step-by-step explanation:
area of a triangle:
½ x b x h
= ½ x 6 x 4
= 3 x 4
= 12.
since there are 8 of the same triangles, they will all have the same area. so to work out the total area of a triangles, we times the area of one triangle by the 8 triangles in the polygon.
12 x 8 = 96.
for the square in the middle:
area of a square = length x width
area of a square = 12 x 12 = 144.
all we need to do is add these two totals together.
144 + 96 =240cm².
we use the units cm², because we have been multiplying xcm x ycm which can be simplified to cm² :)

Answer:
4.9y² + 2y + 4.7
Distributive property
Step-by-step explanation:
[tex]3.9y^2+5.8+4y-1.1-2y+y^2[/tex]
collect and combine like terms:
[tex]\implies 4.9y^2 +2y+4.7[/tex]
Distributive property
The distributive property states that an expression which is given in form of A (B + C) can be solved as A x (B + C) = AB + AC. Similarly, A (B - C) can be solved as A x (B - C) = AB - AC

Solve each inequality. Graph the solution on a on a number line.
p-7/12>3/10
Answer:
so to solve an inequality you just treat the inequaltity sign like an equals sign except if you multiply by negative 1 you flip the direction of the sign.
p-7/12>3/10
add 7/12 to both sides
p>7/12+3/10
p>35/60+18/60
p>53/60
so if you had to graph this on a number line you would have an open circle on 53/60 and an arrow coming off pointing to the right
