Answer:
The mean is 44.2
Step-by-step explanation:
1. Add all the numbers: 29+31+35+37+38+44+43+46+46+93=442
2. Divide the sum by the amount of numbers: Since there are 10 numbers in all our equation is 442 / 10 which equals 44.2 and gives us our answer
Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
Answer:
No, (3, 9) is not a solution of the system.
Step-by-step explanation:
y=3x
2x-y=6
-----------
3(3)=9
2(3)-9=6-9=-3, not 6
Answer:
(x+1)(x-1)(x+3)(x-3)
Step-by-step explanation:
x4-10x^2+9
Group expression so that the coefficients of the x^2 terms add up to +9.
= x^4 -9x^2 - x^2+9
match coefficients in both groups
= x^4 -9x^2 - (x^2-9)
factor each group
= x^2 (x^2-9) - 1(x^2-9)
now factor out the common factor (x^2-9)
= (x^2-1)(x^2-9)
Finally, factor each quadratic factor
= (x+1)(x-1)(x+3)(x-3)
Answer:
Step-by-step explanation:
-
Factor out 
Consider −4p − 2p + 1. Multiply and combine like terms.
-6p + 1
Rewrite the complete factored expression.
