Answer:

Rectangle.

Step-by-step explanation:

If the diagonals are equal then the parallelogram is a rectangle. They are also equal in length in a square, which can be regarded as a special type of rectangle - but in this case the diagonals are perpendicular. They are also perpendicular in a rhombus.

Find the area of the irregular figure.

Diano4ka-milaya [45]

Answer:

The area of the irregular figure is 366 cm sq.

Step-by-step explanation:

This irregular figure is made of 1 Rectangle + 1 right Triangle

Area of the Rectangle:

Length of the rectangle = 21 cm,

Width of the rectangle = 14 cm

AREA of Rectangle = LENGTH x WIDTH

= 21 cm x 14 cm = 294 sq cm

⇒Area of the Rectangle = 294 sq cm ..... (1)

Area of the Right Triangle:

Base of the rectangle = 16 cm,

Height of the rectangle = 21 cm - 12 cm = 9 cm

AREA of Right Triangle = $\frac{1}{2} \times B \times H$

$= \frac{1}{2} \times 16 \times 9 = 72$

⇒Area of the Right Triangle = 72 sq cm ..... (2)

Now, area of the irregular figure = Area of the( Rectangle +Right Triangle)

= 294 sq cm + 72 sq cm = 366 cm sq

Hence, the area of the irregular figure is 366 cm sq.

What ratio of height to width is considered most appropriate in graphing a frequency distribution?

Fiesta28 [93]

Answer:
As a rule of thumb, it is usual to define discrete data in 5 to 10 groups or bins. When graphed, the height of each group or bin defines the frequency for the group or bin.

Explanation:
When discrete data is graphed into a histogram, it defines a frequency distribution. Because information becomes lost when too many groups or bins are used, it is customary to use 5 to 10 bins.

Example:
Consider the following random data which has a sample size of 16.
x = [1, 3, 6, 2, 9, 8, 4, 5, 10, 3, 5, 4, 3, 5, 7, 5]
When fewer groups or bins are used to construct the histogram, the centralized nature of the distribution is easy to discern.
As the number of bins increases, the distribution becomes more difficult to define.
