Using the basis of how we must represent data on a graph, we can write:

A) The scale is 1, and the maximum value is 7.

B)

First, we know that the sample has 25 people in it, an we measure the number of brothers, in such a way that the number of brothers/sisters goes from 0 to 5.

Then, the horizontal axis must go from 0 to 4, in such a way that above the 0 we have 3 dots (because 3 students have 0 brothers or sisters), above the 1 we have 4 dots (because 4 students have one brother or sisters), and so on.

7 students have 2 brothers or sisters (that is the largest number) so the vertical axis must go from 0 to 7.

A) The scale of the line plot is 1, each dot represents 1 student. And the greatest value is 7 (for the students with 2 brothers or sisters).

B)

Answer:

36%

Step-by-step explanation:

Area of circle is

[tex]\pi {r}^{2} [/tex]

If the radius is decreased by 20%. Then the radius will be

80% of the original radius.

So our radius is 0.8.

So our area is

[tex]\pi(0.8r) {}^{2} [/tex]

[tex]\pi(0.64 {r}^{2} )[/tex]

Since pi is constant, the radius only really matters.

We went from

[tex]1 {r}^{2} [/tex]

to

[tex]0.64 {r}^{2} [/tex]

So our area will decrease by 36%

Proof: Let the radius be 10.

So the area of circle will be

[tex]\pi(10) {}^{2} = 100\pi[/tex]

Let our other radius is 8 because 8 is a 20% decrease of the orginal radius

[tex]\pi(8) {}^{2} = 64\pi[/tex]

Next, we subtract the area to find decrease in area

[tex]100\pi - 64\pi = 36\pi[/tex]

Since pi is constant, we can ignore it so our decrease in area is 36%

Y = city C - city D = 2.24 ft

2.24 ft / (1.6 ft / 250 mi) = 350 mi  distance between C and D

Answer:

  20 square units

Step-by-step explanation:

The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.

Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.

  A = bh

  A = (5 units)(4 units) = 20 units²

The area is 20 square units.

Answer:

Step-by-step explanation:

A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.

3x - 4 = 3y + 8 = -2x - 9 = 39

The value of x is 43/3

The value of y is 31/3

The value of z is -24

A rhombus is a quadrilateral where all four sides are equal and the opposite angles are equal.

We have,

Rhombus:

All four sides are equal.

So,

3x - 4 = 3y + 8 = -2x - 9 = 39

Now,

3x - 4 = 39

3x = 39 + 4 = 43

3x = 43

x = 43/3

3y + 8 = 39

3y = 39 - 8

3y = 31

y = 31/3

-2z - 9 = 39

-2z = 39 + 9

-2z = 48

z = -24

Thus,

The value of x is 43/3

The value of y is 31/3

The value of z is -24

Step-by-step explanation:

length × breadth = x² + 5x - 36

let's find, what expression was multiplied by what expression to give that result.

first we see, we have a pure x² term.

so, both start with (x + ...) or (x - ...).

then we see the last (constant) term -36.

so, we have a

(x + a)(x - b)

situation.

36 is the product of

6×6

9×4

12×3

18×2

the term +5x tells us that the difference between a and b must be 5. and a as the positive number must be bigger to give us the "+" (the multiplication contains "... + ax - bx ...").

and that means a = +9, b = -4

so, the original area calculation was

(x + 9)(x - 4) = x² + 5x - 36

when we decrease both factors by 2, we get

(x + 9 - 2)(x - 4 - 2) = (x + 7)(x - 6) = x² + x - 42

that is the new area of the rectangle.

Answer:

828 in²

Step-by-step explanation:

To find the surface area of a triangular prism, you find the area of each side and add them together.

Find the area of each rectangular side:

Side 1 :  9 × 20 = 180 in²

Side 2 : 15 × 20 = 300 in²

Side 3 : 12 × 20 = 240 in²

Find the area of the triangular sides:

Area of a Triangle = [tex]\frac{1}{2}[/tex]bh

As you can see, 9 and 12 both work as the height/base for the triangular sides, so

Δ Side 1 = [tex]\frac{1}{2}[/tex]bh = [tex]\frac{1}{2}[/tex](9)(12) = 54

Δ Side 2 is also 54.

Add the areas of all the sides together:

180 + 300 + 240 + 54 + 54 = 828 in²

Answer:

[tex]\frac{1}{4} -\frac{1}{12} = \frac{3}{12} -\frac{1}{12} =\frac{2}{12}[/tex]

So hence, Your answer is 2/12
