Answer: 230cm²
Step-by-step explanation:
>We can do this by splitting the figure into 2 trapeziums.
>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula: .
>Thus,
Area =
I'll do problem 1 to get you started.
The vertical sides are 3 and x for the left and right figures.
The horizontal sides are 15 and 60 for the left and right figures.
The corresponding sides form fractions which are equal (due to the nature of the similar polygons)
3/x = 15/60
3*60 = x*15 ... cross multiply
180 = 15x
15x = 180
x = 180/15 .... divide both sides by 15
x = 12
----------
Another way you can see this is note how the jump from 15 to 60 is "times 4", so the jump from 3 to x must also be "times 4" to keep the same proportion
3 ---> x = 3*4 = 12
Or you could set up the proportion
60/15 = x/3
4 = x/3
x/3 = 4
x = 3*4
x = 12
-----------
<h3>Final Answer: 12</h3>
Answer:
A two story home might use translation to have both floors identical and most homes have windows of the same size and shape so they might also use translation. Sometimes buildings use reflection to make rooms opposite each other the same.
Step-by-step explanation:
1. The question about the weight of the football team players is statistical because it requires data collection to answer it and the data is variable.
2. The question about the height of Ben's mother is <u>non-statistical</u> because it does not require data collection to answer and the data is not variable, since it is one data point.
<h3>What is a statistical question?</h3>
A statistical question can be answered by collecting data and for which data will vary.
Questions answered with a single data point are <u>not statistical</u> because there is no data variability to answer them.
A statistical question can be determined by the following criteria:
- Provides useful data about a group of people.
- Many people can answer it.
- There will be many different answers.
- The data collected explains a situation or reality.
Thus, the question about the weight of the players asks a statistical question, unlike the height of Ben's mother.
