Answer:

AQ = 20 units

Step-by-step explanation:

Comparing triangle AQR to ABC,

\frac{AQ}{AB} = \frac{QR}{BC}

\frac{4p}{8p} = \frac{2p + 3}{6p-4}

cross multiply and make p the subject of formula, we have:

8p (2p+3) = 4p(6p-4)

16p^{2} + 24p = 24p^{2} - 16p

24p + 16p = 24p^{2} - 16p^{2}

40p = 8p^{2}

divide through by 8p,

p = 5

Therefore, AQ = 4p

                        = 4 × 5

                        = 20

AQ = 20 units

. An urn contains 6 blue and 5 red marbles. Reach in and grab one marble and then another (without replacing the first one). Wha
natima [27]

Probability that you have chosen 2 red marbles is 3/11

<h2>How to solve?</h2>

Total number of marbles = 6 + 5 = 11

Number of red marbles = 6

Number of blue marbles = 5

Important Points:

1. Replacement is not allowed

2. Blue is followed by Red

Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen.

Probability of Blue first = 5/11

Probability of Red second = 6/10 (one marble is already taken out)

Probability = 5/11 * 6/10 = 3/11

otez555 [7]

Answer:

The selection probability to be assigned to each of the package designs is 0.20

Step-by-step explanation:

Firstly, we need to assume that one design is just as likely to be selected by a consumer as any other design

so the probability of selecting any of the design is same and that is 1/5 = 0.20

Thus, what we are trying to say is that each of the package designs have an equal selection probability of 0.20
