Select the correct answer from each drop-down menu. The table shows the heights of the 10 tallest buildings in San Francisco and Los Angeles.

The average height of the 10 tallest buildings in Los Angeles is than the average height of the tallest buildings in San Francisco. The mean absolute deviation for the 10 tallest buildings in San Francisco is

The answer:

Answers

Answer with explanation:

\text{Average}=\frac{\text{Sum of all the observation}}{\text{Total number of Observation}}

Average Height of tallest Building in San Francisco

                    =(260+237+212+197+184+183+183+175+174+173)/(10)\n\n=(1978)/(10)\n\n=197.8

Average Height of tallest Building in Los Angeles

                    =(310+262+229+228+224+221+220+219+213+213)/(10)\n\n=(2339)/(10)\n\n=233.9

→→Difference between Height of tallest Building in Los Angeles and  Height of tallest Building in San Francisco

               =233.9-197.8

               =36.1

⇒The average height of the 10 tallest buildings in Los Angeles is 36.1 more than the average height of the tallest buildings in San Francisco.

⇒Part B

Mean absolute deviation for the 10 tallest buildings in San Francisco

 |260-197.8|=62.2

 |237-197.8|=39.2

 |212-197.8|=14.2

 |197 -197.8|= 0.8

 |184 -197.8|=13.8

 |183-197.8|=14.8

 |183-197.8|= 14.8

 |175-197.8|=22.8

 |174-197.8|=23.8

 |173 -197.8|=24.8

Average of these numbers

     =(62.2+39.2+14.2+0.8+13.8+14.8+14.8+22.8+23.8+24.8)/(10)\n\n=(231.2)/(10)\n\n=23.12

Mean absolute deviation=23.12

Given the following formula solve for y. W=x-y/2 -z

Answers

Answer:

y = 2x + 2W - 2z

Step-by-step explanation:

Add y/2 to both sides of this equation.  We get:

y/2 + W = x - z.

Multiplying all four terms by 2 eliminates the fraction:

y + 2W = 2x - 2z

Subtracting 2W from both sides yields:

y = 2x + 2W - 2z
