Answer:
-21.79.
Step-by-step explanation:
(-10.5 + m) / 11.57 = -2.748
(-10.5 + m) = -2.748 (11.57)
-10.5 + m = -31.794
m = -31.794 + 10.5 = -21.79.
The given polyn. is not in std. form. To answer this question, we need to perform the indicated operations (mult., addn., subtrn.) first and then arrange the terms of this poly in descending order by powers of x:
P(x) = x(160 - x) - (100x + 500)
When this work has been done, we get P(x) = 160x - x^2 - 100x - 500, or
P(x) = -x^2 + 60x - 500
So, you see, the last term is -500. This means that if x = 0, not only is there no profit, but the company is "in the hole" for $500.
Let BS be the event that the patient survives bypass surgery.
Let H be the event that the heart damage will heal.
Then P(BS) = 0.60, and also we have a conditional probability: GIVEN that the patient survives,
the probability that the heart damage will heal is 0.5, that is P(H|BS) = 0.5
We want to know P(BS and H).
Using the formula of the conditional probability:
P(H and BS) = P(H|BS)·P(BS) = (0.6)(0.5) = 0.3
Answer:
3x^11+9x^7+5x^3-x+4
Step-by-step explanation:
A polynomial written in decreasing order is a polynomial that starts with terms with the highest degree and ends with terms to the lowest degree.
First find the decreasing order of the answer:
5x^3-x+9x^7+4+3x^11
3x^11+9x^7+5x^3-x+4
The answer should be this, but I couldn't find a match for it in the answer box.
