Answer:
x^6 +2x^5 -6x^4 +3x^2 +6x-18
Step-by-step explanation:
f(x) = x^2 +2x-6
g(x) =x^4 +3
We are going to multiply them
f(x) * g(x)= (x^2 +2x-6)(x^4 +3)
First (x^2 +2x-6)(x^4) = x^6 + 2x^5 -6x^4
Then x^2 +2x-6)(3) = 3x^2 +6x-18
----------------------------------------------
x^6 +2x^5 -6x^4 +3x^2 +6x-18
÷Answer:
Standard Deviation = 176.5
Step-by-step explanation:
To calculate the standard deviation, calculate the mean score for the 4 standard deviation scores:
mean, m = Σx ÷ n
where Σx represents summation of each value = 162 + 153 + 317 + 413
= 1045
n = number of samples to be considered = 4
mean, m = 1045 ÷4
= 261.25
To calculate the standard deviation, use the formula below
SD =
where x = each value from the week lead time
m = mean = 261.25
n = the size = 4
The Standard deviation formula can be simplified further
when x = 162
= 49.625
when x = 153
= 23.125
when x = 317
= 27.875
when x = 413
= 75.875
Note that the above 4 equations can be lumped up into one giant equation by applying a big square root function instead of breaking it down
SD = 49.625 + 23.125 + 27.875 + 75.875
SD = 176.5
First you make common denominators, which would be 15, what you do to the bottom you have to do to the top so you take 4 times 3 and 2 times 5 so now its 12/15 and 10/15 now you subtract the top which would make it now 10/15 then simpilify down to 2/3. I hope this helps
Answer:
Step-by-step explanation:
(A) We need to show both fraction of same proportion.
Ratio 1:
If we multiply by 3 at numerator and denominator
(B) Now we simplify both ration into simplest form
Step-by-step explanation:
Including all real and imaginary zeros and taking multiplicities into account, every equation of degree n has exactly n roots
