2,000 *20/50 is 800.
800 is your answer.
Answer:
the building would be 280 feet (judging on how this is worded.)
Step-by-step explanation:
you are already 100 meters from the base ( bottom) of the building so you add 180 as you are 180 ft from the top of the building. 100 + 180 is equal to 280.
Answer:2 triangles, 3 rectangles
Step-by-step explanation:
The height scale is 75
Step-by-step explanation:
The height scale is the ratio between the height of the final image and the height of the original image.
In this problem, we have:
(height of the original image)
Converted into meters,
(height of the enlarged image)
Therefore, the height scale is given by the following ratio:
So, the height scale is 75.

Answer:
Notice that the subjects of the study are men over 50 years.
So, you need to consider that each subject is a different person with different weight and other different characteristics that determine that weight.
If we have 10 groups randomly selected, that means there's gonna be variability, otherwise, the study wouldn't make sense.
So, if each person is different, then their weights is gonna be different, giving different means.
It would be rare if both means result equal, beacuse that would mean the subjects had the same weight.
Therefore, the variability between these means can be best attributed to the variability of subjects, the difference between each person.
From a numerical perspective, the variability is attributed to the spread of the data group, that is, if there is too much difference between weights, the variabilty will increase.
