Answer:
the MAD to this set is 6.75
Step-by-step explanation:
The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.
hope that makes sense have a good day
Answer:
The answer is 
.
Step-by-step explanation:
The distance formula:
.
☆All we need to do is plug in!
Factoring out x
x(-3x^2+15x+42) now factor parenthetical expression
x(-3x^2+21x-6x+42)
x(-3x(x-7)-6(x-7))
x(-3x-6)(x-7) we can factor out -3 from first parentheses
-3x(x+2)(x-7)
Answer:
5^1
Step-by-step explanation:
(law of indices - fractional powers)
after converting all the numbers to this form:
combine using law of indices:
5^(2/3+1/2-1/6) = 5^1
Answer: Choice B) -infinity < x < infinity
==========================================================
Explanation:
The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.
Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.
