x^2 + 2x x^2 - 4
------------------- - --------------------
x^2 - 2x - 8 x^2 - 2x - 8
x(x + 2) - (x+2)(x-2)
= --------------------------------------
(x + 2)(x - 4)
(x + 2) ( x - x + 2)
= --------------------------------------
(x + 2)(x - 4)
2
= ------------
(x - 4)
x is NOT equal -2 and 4
I’m pretty sure it’s 240 because you multiply then add
Answer:
Jones(20%), Smiths(30%)
Step-by-step explanation:
The relative dispersion of a data set is the ratio of its standard deviation to its arithmetic mean.
Mr. and Mrs. Jones' neighborhood mean family income is $45,000 with a standard deviation of $9,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
9000:45000
1:5
Expressed as a Percentage: (1/5)x100=20%
The Relative Dispersion of the family incomes in Mr. and Mrs. Jones' neighborhood is 20%
Mr. and Mrs. Smith's neighborhood mean family income is $100,000 and the standard deviation is $30,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
30000:100000
3:10
Expressed as a Percentage: (3/10)x100=30%
The Relative Dispersion of the family incomes in Mr. and Mrs. Smith's neighborhood is 30%
First add the numbers 46=2x3 (1+2)
Then multiply the numbers 46=2x3
Then check the equality 46=6
If it was a true or false I came up with a false but I really hope this helped you
The red line is moving up from left to right, which means it is increasing.
