<u>2. Is also know as the (MAD) or Mean Absolute Deviation of a data set.</u>
Order of operations in a simplified version is PEMDAS, which parenthesis, exponents, multiplication/division, addition/subtraction. so in your equation, 180 + (6-2), you start with what's inside the parenthesis to get 180 + 4. then skip MD bc there's no multiplication or division and move to AS. there is addition, so do addition. so your answer would be 184. however, the associative property is applicable here, so using PEMDAS is not required.
Three sides, because if you make a clean cut the surface of the cut is a triangle.
Answer:
(A) x=5
Step-by-step explanation:
- The length of the pool is 20 feet,
- The width is (20 minus x) feet; and
- The area of the pool is 300 square feet.
Area = Length X Width
300 =20(20-x)
Opening the bracket on the right hand side
300 =400-20x
20x=400-300
20x=100
Divide both sides by 20
x=5
The value of x=5
