<span>Answer:
P(famine | plague) = P(famine and plague) / P(plague) = (0.15) / (0.39) = 0.385</span>
Option #1 (and the fastest):
Multiply both sides by 3 to cancel the “divided by 3” on the left side where z is.
z/3 • 3 = 5/4 •3
z = 15/4
Option #2: Cross multiply and then solve for z:
z/3 = 5/4 -> 4z=15
Then divide by 4.
4z/4 = 15/4
z = 15/4
You're looking for the extreme values of
subject to the constraint
.
The target function has partial derivatives (set equal to 0)


so there is only one critical point at
. But this point does not fall in the region
. There are no extreme values in the region of interest, so we check the boundary.
Parameterize the boundary of
by


with
. Then
can be considered a function of
alone:



has critical points where
:



but
for all
, so this case yields nothing important.
At these critical points, we have temperatures of


so the plate is hottest at (1, 0) with a temperature of 14 (degrees?) and coldest at (-1, 0) with a temp of -12.
g(1)=-1 : We need to check values of function for x=1. From the graph, we can see, for x=1 the value of y is 1.
So, g(1)=-1 is false.
g(0)=0 : We need to check values of function for x=0. From the graph, we can see, for x=0 the value of y is 0.
So, g(0) =0 is true.
g(4)=-2 :We need to check values of function for x=4. From the graph, we can see, for x=4 the value of y is going up but it's not equal to -2.
So, g(4)=-2 is false.
g(1)=1 :We need to check values of function for x=1. From the graph, we can see, for x=1 the value of y is 1.
So, g(1) =1 is true.
g(-1)=1 :We need to check values of function for x=-1. From the graph, we can see, for x=-1 the value of y is 1.
So, g(-1)=1 is true.
g(4)=2 :We need to check values of function for x=4. From the graph, we can see, for x=4 the value of y is going up but it's not equal to 2.
So, g(4)=2 is false.
Answer:
Step-by-step explanation:
(6e-3f-3/4) contains two terms which do not involve fractions and one fractional term (3/4).
We can safely remove the parentheses. Then:
(6e-3f-3/4) => 6e - 3f - 3/4
That is "an equivalent expression."
We could go further and create one equivalent fraction. Multiply the first two terms by 4/4, obtaining:
24e 12f 3 24e - 12f - 3 3(8e - 4f - 1
------ - ------ - ----- => ---------------------- => -------------------
4 4 4 4 4
Other equivalent expressions exist here.
