Final answer:
The missing value in the data set that will preserve the median of 28.5 is 32. This is found by averaging the middle two numbers of the six-number series, solving the equation (25 + missing value)/2 = 28.5.
Explanation:
Calculating the Missing Value in an Ordered Data Set
To determine the missing value in an ordered data set when given the median, you should remember that the median is the middle number in a sorted list of numbers. If the data set has an even number of values, the median is the average of the two middle numbers. For the set 7, 12, 25, _, 41, 50, where the median is given as 28.5, the missing value must be the average of the third and fourth terms since the data set should have six numbers total.
To find the missing value, set up the equation for the median: (25 + missing value)/2 = 28.5. Solve for the missing value:
(25 + missing value) = 28.5 × 2
missing value = (28.5 × 2) - 25
missing value = 57 - 25
missing value = 32
The missing value in the data set to maintain a median of 28.5 is 32.

A rectangular prism measures 2 2/5 inches by 3 1/5 inches by 2 inches
How many cubes with edge length 1/5 inch fit in the prism?
Total 1920 cubes can fit in the given prism.
Given that:Dimensions of prism are: [tex]2\dfrac{2}{5} = \dfrac{12}{5}[/tex] , [tex]3\dfrac{1}{5} = \dfrac{16}{5}[/tex], and 2 inches respectively.
Size of a side of given cube = 1/5 inch
To find:Number of cubes that can fit in given prism.
Calculations and explanation:This problem is all about spaces. Only that number of cube will fit, which the prism will allow to. The given prism has got some space in it(The volume), and the cubes have some size (their volume).
Since prism is a cuboid(which is mistakenly written as rectangular in the question), thus we have:
Volume of prism = multiplication of lengths of its sides = [tex]\dfrac{12}{5} \times \dfrac{16}{5} \times 2 = \dfrac{384}{25}[/tex] cubic inches
Volume of the cube = cube of its one side's length = [tex](\dfrac{1}{5})^3 = \dfrac{1}{125}[/tex] cubic inches
We will divide the total space with space amount each cube take so as to find number of cubes allowed by prism to be fitted in it.
Thus:
[tex]\text{Number of cubes} = \dfrac{\dfrac{384}{25}}{\dfrac{1}{125}} = 1920 \: \rm cubes[/tex]
Thus, in total, there can be 1920 cubes fitted in the prism.

13. A reflection of the rectangle over which line will map the rectangle onto itself?
a. y = 0 b. y=2_c. y=x d. y = 2x
Answer:
Step-by-step explanation:
Y=2
Reflection of a rectangle over the x-axis (y = 0) will generally cause it to map onto itself. The other given lines (y = 2, y = x, and y = 2x) will not typically have this result, unless the rectangle is specifically located on the plane.
Explanation:In geometry, a shape maps onto itself under reflection when it is reflected over a line that bisects it symmetrically. With a rectangle, this can occur when it is reflected over the x-axis or y-axis, assuming the rectangle's sides are parallel to the axes. From the given options, only y = 0 (x-axis) could create this type of reflection.
Reflection over the line y = 0 will leave a rectangle in the same position if its height is evenly distributed above and below the x-axis. For lines like y = 2, y = x, and y = 2x, they would not bisect a rectangle symmetrically unless the rectangle is specifically positioned, so they will not generally result in the rectangle mapping onto itself.

In an equilateral triangle, all 3 sides are equal length, and the perimeter of an equilateral triangle is 3 times the length of one side. If one side measures 9 + 3x, and the measure of another side is 5x – 5, what is the perimeter of the equilateral triangle?
Check the picture below.
Answer:
The perimeter of the equilateral triangle is 90 units.
Step-by-step explanation:
Let the side of the triangle be = s
So, perimeter of equilateral triangle = [tex]s+s+s=3s[/tex]
One side measures 9+3x and the measure of another side is 5x-5.
Both are equal, so we get the sides as:
[tex]9+3x=5x-5[/tex]
[tex]3x-5x=-5-9[/tex]
[tex]-2x=-14[/tex]
x = 7
We get the sides as :
First side [tex]9+3(7)[/tex]
= 30
OR
Second side [tex]5(7)-5[/tex]
= 30
And the third side will also be 30 as it is equilateral triangle.
Hence, the perimeter is = [tex]30+30+30=90[/tex] units
Therefore, the perimeter of the equilateral triangle is 90 units.

To solve this problem, first let x=0.933333(repeating). Then, you want to multiply both sides by 10 to get 10x = 9.33333 (repeating). Next, take equation 2 and minus equation 1 from it giving you 9x = 8.4. Finally, multiply both sides by 10 and you will get 90x = 84. Divide both sides by 90 giving x=84/90. Answer is 84/90. 84/90 can reduce to 14/15.

Using the midpoint formula to equate the x and y coordinates of the endpoints to the x and y coordinates of the midpoint, that is
(6)
let ( x, y ) be the coordinates of the required endpoint, then
x → [tex]\frac{x+6}{2}[/tex] = 2 ( multiply both sides by 2 )
x + 6 = 4 ( subtract 6 from both sides )
x = - 2 and
y → [tex]\frac{y+2}{2}[/tex] = 0 , thus
y + 2 = 0 ( subtract 2 from both sides )
y = - 2
Coordinates of the other endpoint = (- 2, - 2)
(7)
x → [tex]\frac{x-4}{2}[/tex] = - 1 ( multiply both sides by 2 )
x - 4 = - 2 ( add 4 to both sides )
x = 2 and
y→ [tex]\frac{y+3}{2}[/tex] = - 1 ( multiply both sides by 2 )
y + 3 = - 2 ( subtract 3 from both sides )
y = - 5
Coordinates of the other endpoint = (2, - 5)
(8)
x → [tex]\frac{x+7}{2}[/tex] = 2 ( multiply both sides by 2 )
x + 7 = 4 ( subtract 7 from both sides )
x = - 3 and
y → [tex]\frac{y+3}{2}[/tex] = 1 ( multiply both sides by 2 )
y + 3 = 2 ( subtract 3 from both sides )
y = - 1
Coordinates of the other endpoint = (- 3, - 1)
