You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be where BD is your altitude. The formula then, filled in accordingly, would be
. We cross multiply to get that
. Divide both sides by 4 to get
, so x = 5. Choice C is the one you want.
The probability that the letters CO remain next to each other (in order) as a unit is .
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. It is more likely that an event will occur if its probability is higher.
When the letters are arranged randomly in a row, the total number of arrangements is 40,320 , and the number of arrangements with the letters CO next to each other (in order) as a unit is 5,040.
Therefore, possible outcomes = 5040 and
Total outcomes = 40320
Probability =
p =
Therefore, the probability that the letters CO remain next to each other (in order) as a unit is .
