Answer:
0.18 ; 0.1875 ; No
Step-by-step explanation:
Let:
Person making the order = P
Other person = O
Gift wrapping = w
P(p) = 0.7 ; P(O) = 0.3 ; p(w|O) = 0.60 ; P(w|P) = 0.10
What is the probability that a randomly selected order will be a gift wrapped and sent to a person other than the person making the order?
Using the relation :
P(W|O) = P(WnO) / P(O)
P(WnO) = P(W|O) * P(O)
P(WnO) = 0.60 * 0.3 = 0.18
b. What is the probability that a randomly selected order will be gift wrapped?
P(W) = P(W|O) * P(O) + P(W|P) * P(P)
P(W) = (0.60 * 0.3) + (0.1 * 0.7)
P(W) = 0.18 + 0.07
P(W) = 0.1875
c. Is gift wrapping independent of the destination of the gifts? Justify your response statistically
No.
For independent events the occurrence of A does not impact the occurrence if the other.
Answer:
38
Step-by-step explanation:
Given that,
x = -4
f(x)=x² - 4x +6
so,
f(-4)= (-4)² - 4 . (-4) +6
=16 +16 +6
= 38

Answer:
The answer is Point N
Step-by-step explanation:
Nothing more
Let's call the number you thought of n. Then what the two steps you took can be written as an equation:
![n+4\frac{5}{7}=12n](https://tex.z-dn.net/?f=n%2B4%5Cfrac%7B5%7D%7B7%7D%3D12n)
Subtract n to get all of your variables to one side:
![4\frac{5}{7}=11n](https://tex.z-dn.net/?f=4%5Cfrac%7B5%7D%7B7%7D%3D11n)
At this point, I recommend turning your mixed number into an improper fraction. It will make things easier later on:
![\frac{33}{7}=11n](https://tex.z-dn.net/?f=%5Cfrac%7B33%7D%7B7%7D%3D11n)
Now divide both sides by 11 to get the value of n:
