Answer:
Step-by-step explanation:
Hello
please find attached the graph
you can notice that
(a) from the graph we can say that there is no maximum and one minimum in x = 3
and then f(3) = 0 so o is the minimum of f
(b) vertex is (3,0)
(c) x = 3 is an axis of symmetry
(d) as the root is 3
(e) y=9 for x = 0 so the y-intercept is 9
do not hesitate if you need further explanation
if you like my answer, tag it as the brainliest :-)
Answer:
And using the probability mass function we got:
Step-by-step explanation:
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find the following probability:
And using the probability mass function we got:
Answer:
Step-by-step explanation:
since AD is a median it implies that triangle ABC is bisected to two equal right angled triangle which are ADB and ADC.
FE is parrallel to BC and cuts AB at F and AC at E shows that there are two similar triangles formed which are AFE and ABC.
Recall that ADC is a right angled triangle, ED bisects a right angled triangle the the ADE = .
Now, Let FD bisect angle ADB,
then ADF = too.
Since AFX is similar to Triangle ABD and that Triangle AEX is similar to Triangle ACD, then EDX is similar to FDX
FDE = ADF + ADE =
