Answer:

Step-by-step explanation:

Replace are and base to get:

82.5 = 1/2 x 15 x height

A rectangle has an area of 30 m² and a perimeter of 34 m. What are the dimensions of the rectangle?
romanna [79]
Length is l
width is w
l*w = 30
2l + 2w = 34

You can simplify the second equation to l + w = 17

Factors of 30:
30*1
15*2
10*3
6*5

Try adding each of these factors together, to find out which equals 17

30 + 1 = 31
15 + 2 = 17
10 + 3 = 13
6 + 5 = 11

So the dimensions of the rectangle are 15m * 2m

djyliett [7]

Answer:

E. a contingency table

Step-by-step explanation:

First we need to identify the number of variables in the survey. The choice of graphical display depends on the number of variables and their types.

The survey was conducted to study the relationship between:

1) Whether the family is buying or renting their homes

This is a categorical variable with 2 possible options

2) Marital Status of the Parents

This is also a categorical variable with 4 possible options: Married, single, divorced, and widowed

This means, we have to display 2 categorical variables side by side, showing their relationship. To display such data we always use a contingency table.

A contingency table or a 2-way table is a type of Frequency Distribution that is used to summarize the relationship between two or more Categorical Variables. Its similar to matrix form i.e. in form of rows and columns of a table. The minimum size is 2 rows and 2 columns.

An example of the contingency table that can be drawn for a data collected in a similar survey is shown in the image below.

Scale:6 cm =30m drawing length 15 cm actual length
Oxana [17]
6 cm = 30m

find out how much meters 1 cm is equal too. Divide 6 from both sides

6cm/6 = 30,=m/6

cm = 30/6

cm = 5m

So for every centimeter, it equals 5 meters

You have 15 centimeter, so multiply 5 to it

15 x 5 = 75

75 meters is your final answer
