Step-by-step explanation:
1. Write a short definition of each statistical term (mean, median, and mode).
2. Provide an example of each statistical term (mean, median, and mode).
3. Then describe how you might use each term in your daily activities, such as grocery shopping.
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.
Step-by-step explanation:
On a piece of paper, use a protractor to construct a triangle with angle measures of 30° and 40°.
Select from the drop-down menu to correctly classify the triangle.
A triangle with angle measures of 30° and 40° is
Acute
obtuse
right
Step-by-step explanation:
The answer is b. an obtuse. This is because if it were a right-angled triangle, then 90 + 30 + 40 would equal 180 and it doesn't. It's obtuse because 30 + 40 = 70, and triangles have to add up to 180° so the last angle would need to be 110°, which is an obtuse angle. I hope this helps!

Help, I need to figure this out.
Answer:
1) y = -1/2x - 1
2) y = -1
3) y = -2/4
4) y = 5/2 - 3
Step-by-step explanation:
1)
use rise (up or down) over run (left or right)
the rise is -1
the run is 2
therefore, the slope is -1/2
the y intercept is -1 (y intercept is when it touches the Y line)
y = -1/2x - 1
2)
y = -1
3)
y = -2/4
4)
y = 5/2 - 3

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

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.

Here's pic:
Inaaya has a jar of coins containing only nickels, dimes, and quarters. A nickel is
worth 5 cents, a dime is worth 10 cents, a quarter is worth 25 cents, and a dollar
is worth 100 cents.
The ratio of the number of quarters to the number of dimes to the number of
nickels in the jar is 9 : 3 : 1. The total value of all the coins in the jar is $18.20.
How many coins does Inaaya have in her jar?
Answer:
91 total coins
63 quarters, 21 dimes, 7 nickels
Step-by-step explanation:
What I did first was did (9 * 0.25) + (3 * 0.10) + (1 * 0.05) to establish a formula. Next, I did trial and error until I met the appropriate number, but since they needed to stay within a ratio, every time I increased the nickels by one, I needed to increase the dimes by 3 and the quarters by 9. I eventually got to (63 * 0.25) + (21 * 0.10) + (7 * 0.05) = $18.20
A dollar is usually divided as nickels, dimes and quarters. The total number of coins Inaaya have in her jar is 91
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where [tex]x[/tex] is a common factor (not 1)
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
For the given case, let Inaaya has got the number of coins per type as:
Number of nickels = xNumber of dimes= yNumber of quarters = zThus, total number of coins she get = x + y + z
Since we know that: a Nickel = $0.05, a Dime = $0.10, and a Quarter = $0.25
Thus,
Total value of money = [tex]$0.05 \times x + 0.10 \times y + 0.25 \times z[/tex] (in dollars)
Since it is given that she has got total amount in dollars as $18.20, thus,
[tex]0.05x + 0.1y + 0.25z = 18.2\\[/tex]
Also, let the ratio given is by cancelling a factor F, then
as it is given that:
Number of quarter : Number of dime : Number of nickel = 9 : 3 : 1
Number of quarters = z = 9FNumber of dimes = y = 3FNumber of nickels = x = 1F = FThen, using the equation we got for x, y, and z, we get:
[tex]0.05x + 0.1y + 0.25z = 18.2\\\\0.05(F) + 0.1(3F) + 0.25(9F) = 18.2\\0.05F + 0.3F + 2.25F = 18.2\\2.6F = 18.2\\F = 18.2/2.6 = 7[/tex]
Thus, number of quarters = 9F = 9 times 7 = 63
Number of dimes = 3F = 3 times 7 = 21
Number of nickels = 1F = F = 7
Total coins = 63 + 21 + 7 = 91
Thus, the total number of coins Inaaya have in her jar is 91

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 :)
