Does anyone know what absolute deviation is..?
Ostrovityanka [42]

Answer:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Step-by-step explanation:

To find the mean absolute deviation of the data, start by finding the mean of the data set. Find the sum of the data values, and divide the sum by the number of data values. Find the absolute value of the difference between each data value and the mean: |data value – mean|.

A person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20
lorasvet [3.4K]

Answer:

21.27 meters.

Step-by-step explanation:

Please find the attachment.

Let H and h represent height of building and tree respectively.

We have been given that a person on the ground looks up at an angle of 28° and sees the top of a tree and the top of a building aligned. The tree is 20 m away from the person and the building is 60 m away from the person.

We know that tangent relates opposite side of a right triangle with its adjacent side.

\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}

\text{tan}(28^{\circ})=\frac{H}{60}

60\cdot \text{tan}(28^{\circ})=H

60\cdot 0.531709431661=H

H=31.90256589966\approx 31.90

Similarly, we can find height of the tree.

\text{tan}(28^{\circ})=\frac{h}{20}

20\cdot\text{tan}(28^{\circ})=h

20\cdot 0.531709431661=h

h=10.63418863322\approx 10.63

H-h=31.90-10.63

H-h=21.27

Therefore, the difference in heights between the building and tree is 21.27 meters.
