Answer:
The mean is 77.
Step-by-step explanation:
Step one: add all the numbers
Step two: Divide the sum by the number of values you added
(example: 1,5,8,12,13. You would add them together, since we have 5 numbers, we will divide the sum by 5, then we have the mean)
462 divided by 6 is 77

Answer:
11.8
Step-by-step explanation:
5 + 10 + 12 + 4 + 6 + 11 + 13 + 51= 118
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.
Count = 10
Sum = 118
Average = Sum / Count
118/10= 11.8

6x -3y -15 = 0 please solve for me
Step-by-step explanation:
Add 3y to both sides
6x-3y- 15 + 3y =0+3y
Simplify
6x- 15 =3y
Add 15 to both sides
6x-15 + 15 =3y + 15
Simplify
6x =3y+ 15
Divide both sides by6
6x/6= 3y/6+ 15/6
x=y+5/2

A circular flower garden surrounds a sculpture on a square base as shown. What is an expression for the area of the flower garden?
The number from the center of the square is 6x and the flower garden area is 4x
The given object is made up of circle and squares. The expression for the area of the flower garden is 4π²(9π - 4)square units
Area of composite objectThe given object is made up of circle and squares. To find the area of the garden, we wil use the expression
Area of the garden = area of circle - area of square
Find the area of circle
Area = πr²
Area = π(6π)²
Area pf circle = 36π³ square units
For the square
A = length * length
A = 4²π²
A = 16π²square units
Take the difference
D = 36π³ - 16π²
D =4π²(9π - 4)square units
Hence the expression for the area of the flower garden is 4π²(9π - 4)square units

Answer: (pi * r^2) - (6x*4x)
Step-by-step explanation:
Since the formula of the area of a circle is pi * r^2 and the area of a square is base* height or in this case 6x*4x the answer is: (pi * r^2) - (6x*4x). The reason we subtract is because your trying to find the area of the square inside the circle.

Find the surface area of this triangular prism. Be sure to include the correct unit in your answer.
The number that indicates the extent of a region on a plane or a curved surface is known as area. The total surface area of this triangular prism is 1,782 cm².
What is the area?The number that indicates the extent of a region on a plane or a curved surface is known as area. The area of a plane region or plane area refers to the area of a form or planar lamina, whereas the area of an open surface or the border of a three-dimensional object is referred to as surface area.
The given figure has two rectangles and two triangles, therefore, the total surface area can be written as,
[tex]\rm Total\ Surface\ Area =\text{Surface area of rectangle1} + \text{Surface area of rectangle2} + (2 \times \text{Surface area of triangle})\\[/tex]
Substitute the dimensions we will get,
[tex]\rm Total\ Surface\ Area =( 25 \times 30)+ (24 \times 25) + (2 \times \dfrac12 \times 18 \times 24)[/tex]
[tex]\rm = 750+600+432\\\\=1,782\ cm^2[/tex]
