In the figure, AB is tangent to circle C. Find the length of DB.​
Andreyy89

Answer:

8.5

Step-by-step explanation:

First we need to get BC using the pythagoras theorem

BC² = AC² + AB²

BC² = 8² + 15²

BC² = 64+225

BC² = 289

BC = √289

BC = 17

DB = 1/2BC

DB = 1/2 * 17

DB = 8.5

Hence the length of DB is 8.5

The ____________ of probability tells that to determine the chances of independent events, such as the likelihood of inheriting
____ [38]

Answer:

The product rule of probability tells that to determine the chances of independent events, such as the likelihood of inheriting a certain allele, probabilities are multiplied

Step-by-step explanation:

The product rule of probability states that the probability of independent events occurring together can be gotten by multiplying the probability of each event occurring alone.

The product rule is given as P(A*B) = P(A) *P(B).   Where A and B are two independent events. For example when picking cards from a deck of 52 cards, the probability of getting an ace is 4/52 = 1/13 (because there are 4 aces in a deck of 52 cards) . The probability of picking a heart is 13/52 = 1/4. Therefore the probability of picking the ace of hearts is 1/4*1/13 =1/52.
