Answer:
The zeroes are 2, -2, -6, 5.
Step-by-step explanation:
If 2 of the zeroes are 2 and -2 then (x - 2)(x + 2) is factor of the polynomial.
We can now do long division.
Note (x - 2)(x + 2) = x^2 - 4, so we have:
x^2 - 4 ( x^4 + x^3 - 34x^2 - 4x + 120 ( x^2 + x - 30 <--- Quotient
x^4 - 4x^4
x^3 - 30x^2 - 4x
x^3 -4x
-30x^2 + 120
-30x^2 + 120
x^2 + x - 30 = 0
(x + 6)(x - 5) = 0
x = -6, 5.
In hypothesis testing the claim that we have to test always goes into alternative hypothesis. The null hypothesis is negation of claim.
Here the claim to be tested is James bond can taste the difference between a martini that is shaken and one that is stirred.
So negation of this claim is James bond can not taste the difference between a martini that is shaken and one that is stirred.
So the null hypothesis for given experiment is
Null hypothesis: James bond can not taste the difference between a martini that is shaken and one that is stirred.
Alternative hypothesis: James bond can taste the difference between a martini that us shaken and one that is stirred.
6,00 because you have to add them up then divide the the last nimber and you should get 6,000
