We'll need to find the 1st and 2nd derivatives of F(x) to answer that question.
F '(x) = -4x^3 - 27x^2 - 48x - 16 You must set this = to 0 and solve for the
roots (which we call "critical values).
F "(x) = -12x^2 - 54x - 48
Now suppose you've found the 3 critical values. We use the 2nd derivative to determine which of these is associated with a max or min of the function F(x).
Just supposing that 4 were a critical value, we ask whether or not we have a max or min of F(x) there:
F "(x) = -12x^2 - 54x - 48 becomes F "(4) = -12(4)^2 - 54(4)
= -192 - 216
Because F "(4) is negative, the graph of the given
function opens down at x=4, and so we have a
relative max there. (Remember that "4" is only
an example, and that you must find all three
critical values and then test each one in F "(x).
Question: Which of the following is NOT true when testing a claim about a proportion?
Answer: A conclusion based on a confidence interval estimate will be the same as a conclusion based on a hypothesis test.
I don't really know the answer choices, but I think that's right. Sorry if not.
Hope this helps. c;
Answer:
Step-by-step explanation:
calculate :
f(-1) =3(-1)-5 = - 8
f(5) =3(5)-5 = 10
f(2) =3(2)-5 = 1
f(4) =3(4)-5 = 7
the range is : E = {-8.10,1,7}
Answer:
3/2 or 1 1/2
Step-by-step explanation:
We are told that:
Obasi earns 150% of his regular hourly wage while working overtime
The fraction of his regular hourly wage that Obasi earns while working overtime is written as:
150%
= 150/100
= 15/10
= 3/2
= 1 1/2
The fraction of his regular hourly wage that Obasi earns while working overtime is 3/2 or 1 1/2
Answer:
Step-by-step explanation:
ax² + bx + c = y
Plug in data points to get a system of equations in three unknowns.
(0.5,18): 0.25a + 0.5b + c = 18
(1,24): a + b + c = 24
(1.5,22): 2.25a + 1.5b + c = 22
Solving the system: a = -16, b = 36, c = 4
y = -16x² + 36x + 4
When x = 1.7, y = -16·1.7² + 36·1.7 + 4 = 18.96 ft
