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:

**Answer with explanation:**

Average Height of tallest Building in San Francisco

Average Height of tallest Building in Los Angeles

→→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**

**Mean absolute deviation=23.12**

Answer:

1st -36.1 meters or more

2nd -23.12

Step-by-step explanation:

**Answer:**

They're 24 in total so i guess it would be 24 units^2

**Step-by-step explanation:**

24!!! i hope you make them proud :)

by a comma.

5x2 + 2x - 7 = 0

**Answer:**

it equals 1

**Step-by-step explanation:**

(5)(2)+2x−7=5

Step 1: Simplify both sides of the equation.

(5)(2)+2x−7=5

10+2x+−7=5

(2x)+(10+−7)=5(Combine Like Terms)

2x+3=5

2x+3=5

Step 2: Subtract 3 from both sides.

2x+3−3=5−3

2x=2

Step 3: Divide both sides by 2.

2x

2

=

2

2

x=1

√(-4x) = 100

-4x = 100² = 10,000

x = 10,000/-4 = -2500

The solution is ...

x = -2500

-4x = 100² = 10,000

x = 10,000/-4 = -2500

The solution is ...

x = -2500

Answer:

$56

Step-by-step explanation:

Multiply to find how much he took out.

18 * 8 = 144

Subtract to find how much he has left.

200 - 144 = 56

Best of Luck!
