Answer:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.

Find the values of x:
I don’t understand how to do this please help
Answer:
x = 8
Step-by-step explanation:
11x - 34 and 7x - 2 are vertical angles and congruent, thus
11x - 34 = 7x - 2 ( subtract 7x from both sides )
4x - 34 = - 2 ( add 34 to both sides )
4x = 32 ( divide both sides by 4 )
x = 8
-----------------------
11x - 34 = 11(8) - 34 = 88 - 34 = 54
18y and 11x - 34 are adjacent angles and supplementary , thus
18y + 54 = 180 ( subtract 54 from both sides )
18y = 126 ( divide both sides by 18 )
y = 7
Simon is doing an obstacle course in gym class. First, he runs 500 meters and jumps over a hurdle. Then, he crawls through a 20-meter tunnel. Finally, he dribbles a soccer ball 100 meters to the finish line. How many kilometers long is the obstacle course?
kindly need some answers
Angle A = 100 (supplementary to the 80 angle)
Angle D = 100 (same reason)
Angle I = 130 (supplementary to the 50 angle)
Angle K = 100 (supplementary to angle H, and angle H = 80 since it is corresponding to the 80 angle)
Angle E = 80 (supplementary to angle A, and angle A = 100)
Note : Supplementary angles add up to 180, and corresponding angles are equal to each other. (with the condition of 2 lines are parallel to each other.)
Answer:
Angle A = 100
Angle D = 100
Angle I = 130
Angle K = 100
Angle E = 80

2. Describe your strategy for finding the area that needs to be painted. (2 points)
3. Find the area of each shape. Use 3.14 for π. (4 points)
4. What is the total area to be painted? (2 points)
Answer:
2. do part 3, then subtract area not painted from the overall area
3. triangle: 16 ft²; semicircle: 6.28 ft²; rectangle: 48 ft²
4. 57.72 ft²
Step-by-step explanation:
2.The area that needs to be painted can be found by determining the overall area of the shape and subtracting the area that is not painted.
__
3.The area of the triangle is given by the formula:
A = 1/2bh
A = 1/2(8 ft)(4 ft) = 16 ft²
The area of the semicircle is ...
A = 1/2πr²
A = 1/2(3.14)(2 ft)² = 6.28 ft²
The area of the rectangle is ...
A = bh
A = (8 ft)(6 ft) = 48 ft²
__
4.The triangle and rectangle are painted. They constitute the overall shape of the set piece. The semicircular window is a hole, so does not need to be painted. Then the painted area is ...
triangle area + rectangle area - semicircle area
= 16 ft² +48 ft² -6.28 ft² = 57.72 ft² . . . painted area
What is the equation of the line that passes through the point -4, —8) and has a
slope of 4?
Answer:
y = 4x + 8
Step-by-step explanation:
A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.
Since you know that the slope is 4, all you need to do is find the y-intercept (constant)
y = 4x + c
Sub in the points (-4, -8)
-8 = 4(-4) + c
-8 + 16 = c
c = 8
Hence, y = 4x + 8

Based on the type of equations in the system, what is the greatest possible number of solutions? StartLayout Enlarged left-brace 1st Row x squared y squared = 9 2nd row 9 x 2 y = 16 EndLayout 1 2 3 4.
The possible number of solutions to the equations in the system is 2. A solution is a collection of data designated to the unexplored variables.
What is the solution?A solution is a set of values assigned to the unknown variables that ensure the equation's equality.
To put it another way, a solution is a value or a set of values (one for each unknown) that, when substituted for the unknowns, makes the equation equal.
The given system of equation is;
[tex]x^2+y^2=9[/tex]
The standard equation of the circle is;
[tex](x-h)^2+(y-k)^2=r^2[/tex]
On comparing the given equation with the standard equation;
The first equation shows the center is at origin(0,0). and radius is 3.
The second equation shows the given equation is a straight line.
As we know that a straight line can only intersect a circle at a maximum of 2 points.
Hence the possible number of solutions to the equations in the system is 2.

Maya has 120 caramel apples to sell. Each caramel is covered with one topping. 1/5 of the caramel apple are covered with peanuts 1/3 are covered with chocolate chips 3/10 are covered with coconut The rest with sprinkles How many caramel apples are covered with sprinkles
Answer:
20 caramel apples are covered with sprinkles
Step-by-step explanation:
Let the fraction representing total number of apples = 120 = 1
We are told in the question:
1/5 of the caramel apple are covered with peanuts 1/3 are covered with chocolate chips 3/10 are covered with coconut The rest with sprinkles
Hence:
1 = 1/5 + 1/3 + 3/10 + Sprinkles
Sprinkles = 1 - (1/5 + 1/3 + 3/10)
LCM = 30
1 - (6 + 10 +9/30)
1 - 25/30
1 - 5/6
Fraction of caramel apples covered sprinkles = 1/6
The number caramel apples covered with sprinkles = 1/6 of 120 caramel apples
= 1/6 × 120
= 20 caramel apples are covered with sprinkles

The zeros of a polynomial are 3/2 and 2/5. Find the polynomial.
___x²− ___x+6
Let the zeros of a polynomial be α and β.
Here,
α:- 3/2β:- 2/5Therefore to find the equation of polynomial we have to do sum of zeros of the polynomial and the product of zeros of the polynomial.
Sum of the zeros of polynomial are :-
[tex] \sf \alpha + \beta = \frac{3}{2} + \frac{2}{5} \\ \\ : \rightarrow \: \frac{15 + 4}{10} = \frac{19}{10} [/tex]
Product of the zeros of polynomial are:-
[tex] \sf \: \alpha \beta = \frac{3}{2} \times \frac{2}{5} \\ \\ : \rightarrow \cancel\frac{6}{10} = \frac{3}{5} [/tex]
We know,
p(x) = x² - (α +β)x + αβ
putting values we get
p(x) = x² - 19/10x + 3/5
Hence, This is the required polynomial.
Make a table for the equation.
The first row is an example.
Answer:
Substitute the given values of x into the given equation to find the values of y:
when x = -8
[tex]y=\dfrac54(-8)+1=-9[/tex]
Point = (-8, -9)
when x = -4
[tex]y=\dfrac54(-4)+1=-4[/tex]
Point = (-4, -4)
when x = 0
[tex]y=\dfrac54(0)+1=1[/tex]
Point = (0, 1)
when x = 4
[tex]y=\dfrac54(4)+1=6[/tex]
Point = (4, 6)
when x = 8
[tex]y=\dfrac54(8)+1=11[/tex]
Point = (8, 11)

A triangle has sides with lengths of 11 inches, 18 inches, and 20 inches. Is it a right triangle?
yes IF
20² = 11² + 18²
20² = 400
and
11² + 18² = 121 + 324 = 445
so NOT a right triangle
Which equation for g(x) represents the transformation of f(x) given that f(x) =x^2
g(x) = f(x) shifted right 2 units
Help!!
Answer:
g(x) = (x - 2)²
Step-by-step explanation:
If we want to shift a function to the right, we subtract the number we are asked to move to the right inside the function's argument:
⇒ To shift f(x) b units to right → f(x - b)
Similarly, in function notation, if we want to shift a function to the left, we add the number we are asked to move to the left inside the function's argument:
⇒ To shift f(x) b units to left → f(x + b)
Given function f(x) = x²
Shift 2 units to the right: f(x - 2) = (x - 2)²
Therefore, g(x) = (x - 2)²
----------------------------------------------------------------------
Additional info:
g(x) = (x - 2)²
= (x - 2)(x - 2)
= x² - 4x + 4

Answer:
B
Step-by-step explanation:
consider the coordinates of T and T'
T (1, - 2 ) and T' (- 3, 1 )
1 → - 3 in the x- direction is - 4
- 2 → 1 in the y- direction is + 3
then the translation rule is (x, y ) → (x - 4, y + 3 )
A nonagon has angles that measure 150°, 130°, 130°, 150°, 140°, 140°, 150°, 130°, and d. What is d?
Answer:
d = 140°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
a nonagon has 9 sides , then
sum = 180° × 7 = 1260°
sum the angles and equate to 1260
150° + 130° + 130° + 150° + 140° + 140° + 150° + 130° + d = 1260°, that is
1120° + d = 1260° ( subtract 1120° from both sides )
d = 140°
