Recall the inclusion/exclusion principle:

which means
The answer is 5.6 because 2+2+4+5+5+6+7+7+8+10=56
and 56/10=5.6
To find the mean<span>, add all the values together and divide by the number of values in the set. The result is your </span>mean<span>!

Answer:
Simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Step-by-step explanation:
As the expression given in the question be as follow .
= (x−3)( x²−4x−7)
simplify the above
= x (x²-4x-7)-3 (x²-4x-7)
Now open the bracket
= x³ - 4x² -7x - 3x² + 12x + 21
= x³- 4x²-3x²-7x + 12x + 21
= x³ -7x² + 5x + 21
Thus the simplification of the expression (x−3)( x^2−4x−7) is x³ -7x² + 5x + 21 .
Answer:
Step-by-step explanation:
Putting values into the equation
14(1) - 4 - 2(4)
14 - 4 - 8
10 - 8 = 2
