Answer:
0.818
Step-by-step explanation:
Since the shipment has a ton of aspirin tablets, we can assume that we pick 13 of them <em>with</em> <em>reposition, </em>because the probability shoudn't change dramatically from the probability of picking without reposition if we do so.
We call D the amount of defective tablets. If we assume that we pick the tablets with reposition, then we obtain that D is a random variable of Binomial distribution with parameters 13 and 0.6 (the probability of picking a defective tablet).
We want D to be at most one. To calculate the probability of that event we add up the probability of D being equal to 0 and the probability of D being equal to one. Since D is binomial, we have
We conclude that
Hence, the shipment will be accepted with probability 0.818

Answer:
It is given that , In ΔW X Y, Y X is perpendicular to W Z. Also, y w= w z.
To Prove: ΔW X Y ≅ ΔZ Y X
Proof:
In Δ W X Y and Z Y X
Y X ⊥ W Z→→→→Given
Y W= Y Z→→(Given)
∠YWX=∠YZX→→As, opposite sides of a triangle are equal, so angle opposite to them are equal.
∠YXW=∠YXZ→→Each being 90°
So, ΔYXW≅ΔYXZ→→[AAS]
Also, YX is common sides between two triangles.
ΔYXW≅ΔYXZ→→[HL]
So,the two triangles can be proved congruent by either AAS, or HL.
