Answer:
Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.
Step-by-step explanation:
The expression "f(x)" means "plug a value for x into a formula f "; the expression does not mean "multiply f and x"! Don't embarrass yourself by pronouncing or thinking of "f(x)" as being "f times x". In notation, the "x" in "f(x)" is called "the argument of the function", or just "the argument".
Answer:
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|.
Step-by-step explanation:
Calculate Mean Absolute Deviation (M.A.D)

Answer:
Rectangle B is a scaled copy of rectangle A.
Enlargement scale factor = 1.25
Step-by-step explanation:
<u>Rectangle A:</u>
Length = 12 units
Width = 8 units
<u>Rectangle B:</u>
Length = 15 units
Width = 10 units
<u>Rectangle C:</u>
Length = 30 units
Width = 15 units
Rectangle B length ÷ rectangle A length = rectangle B width ÷ rectangle A width = 1.25
i.e 
= 
= 1.25
Hence rectangle B is a scaled copy of rectangle A and the scale factor of enlargement is 1.25
