I think we use sets here...I'm not really sure but I think you just make a code like {1245679} {2456791} {4567912} {5679124} {6791245} {7912456} {9124567}. it's a bit confusing but I would say that 7 codes are possible. I'm not entirely sure. but hopefully I'm right?

Suppose that 70% of the orders on a particular website are shipped to the person who is making the order and the remaining 30% a
Lera25 [3.4K]

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.

Find the value of x.<br><br>• 5<br>• 20<br>• 40<br>• 45​
insens350 [35]

Answer:

3rd option: x= 40

Step-by-step explanation:

4x° +20°= 180° (adj. ∠s on a str. line)

<em>Bringing</em><em> </em><em>constants</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>:</em>

4x°= 180° -20°

<em>Simplify</em><em>:</em>

4x°= 160°

<em>Divide</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>

x°= 40°

Thus, x=40.
