Answer:

  A.  40.7%

Step-by-step explanation:

The selling price for a $5 profit will be ...

  $12.75 +5.00 = $17.75

From $29.95, this represents a change of ...

  (17.75 -29.95)/29.95 × 100%

  = -12.20/29.95 × 100% ≈ -40.7346%

The bookstore can offer a maximum discount of about 40.7%.

Suppose that P(A) = 0.4 and P(B) is unknown. (a) Is it possible that P(A and B) = 0.5? Explain why or why not. (b) Is it possibl
zhannawk [14.2K]

Answer and explanation:

Given : Suppose that P(A) = 0.4 and P(B) is unknown.

To find :

(a) Is it possible that P(A and B) = 0.5? Explain why or why not.

P(A) = 0.4

So, P(A and B) cannot be 0.5 because maximum value of P(A and B) is the lowest of P(A) and P(B).

The range of P(A and B) is 0 to 0.4.

Therefore, P(A and B) cannot be greater than P(A).

(b) Is it possible that P(A and B) = 0.3? Explain why or why not.

Yes, it is possible as P(A and B) = 0.3 < P(A)=0.4

(c) Is it possible that P(A or B) = 0.5? Explain why or why not.

Its is possible that P(A or B) = 0.05,

As P(A or B) can have a least value equal to highest of P(A) and P(B) and maximum value of P(A or B) is 1.

So, P(A or B) can be any value within the range 0.4 to 1.

(d) Is it possible that P(A or B) = 0.3? Explain why or why not.

P(A or B) cannot be 0.3 as the least value of P(A or B) is 0.4.

The triangles that are similar would be ΔGCB and ΔPEB  due to Angle, Angle, Angle similarity theorem.

<h3>How to identify similar triangles?</h3>

From the image attached, we see that we are given the Parallelogram GRPC. Thus;

A.  The triangles that are similar would be ΔGCB and ΔPEB  due to Angle, Angle, Angle similarity theorem.

B. The proof of the fact that ΔGCB and ΔPEB are similar pairs of triangles is as follow;

∠CGB ≅ ∠PEB  (Alternate Interior Angles)

∠BPE ≅ ∠BCG  (Alternate Interior Angles)

∠GBC ≅ ∠EBP  (Vertical Angles)

C.  To find the distance from B to E and from P to E, we will first find PE and then BE by proportion;

225/325 = PE/375  

PE = 260 ft

BE/425 = 225/325  

BE = 294 ft
