Answer:
Step-by-step explanation:
The given polynomial has zeros at:
x=−3, x=−1, and x=1.
This means that:
x+3, x+1, and x-1 are all factors of this polynomial.
The factored form of this polynomial is :
We expand the last two factors using difference of two squares.
This is the standard form because it is now in decreasing powers of x.
Answer:
the simplified form is 3/5
Step-by-step explanation:
Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = 
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = 
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
Answer:
The answer is 162.5
Step-by-step explanation:
you divide 2 by 3 and then figure out how many examples where given to find the average and multiply by that much and you get the answer.
