Step-by-step explanation:
Divide 135 by 5 and you will get 27.
27 times 4 is 108.
135-108=27
Answer:
So possibilities of zeroes are:
Positive Negative Imaginary
1 1 2
3 1 0
Zeroes = -1.4549, 1.2658, 0.34457-1.0503i, 0.34457+1.0503i.
Step-by-step explanation:
Note: Descartes' Rule of Signs is used to find the signs of zeroes not the exact value.
The given function is
Degree of polynomial is 4 so number of zeroes is 4.
There are three sign changes, so there are either 3 positive zeros or 1 positive zero.
Now, put x=-x in f(x).
There is one variation in sign change, so there is 1 negative zero.
So possibilities of zeroes are:
Positive Negative Imaginary
1 1 2
3 1 0
Using graphing calculator the zeroes of given function are -1.4549, 1.2658, 0.34457-1.0503i and 0.34457+1.0503i.

Answer:
b. 0.80
Step-by-step explanation:
The probability distribution means that we have these following probabilities:
0.05 probability of having a loss of $100.
0.15 probability of having neither a loss nor a profit.
0.30 probability of a profit of $200.
0.40 probability of a profit of $300.
0.10 probability of a profit of $400.
On a given day, the probability the bakery will have a profit of $200 or more is
Either 200, 300 or 400.
Looking at it's probabilities;
0.3 + 0.4 + 0.1 = 0.8
So the correct answer is:
b. 0.80
