Misalkan Anda memiliki sebuah koin: ini berarti ia memiliki kesempatan 50% kepala arahan dan kesempatan 50% dari arahan ekor up. Misalkan Anda flip itu tiga kali dan membalik ini independen. Berapa probabilitas bahwa mendarat kepala, kemudian ekor, kemudian mengepalai? Jadi jawabannya adalah 1/8, atau 12,5%

In English:Suppose you have a fair coin: this means it has a 50% chance of landing heads up and a 50% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5%

Jeremy bought a new truck for $32,000. The value of the truck after t years can be represented by the formula V = 32,000(.8)^t.

blondinia [14]

$6700=32000(0.8)^t$
divide both sides by 32000
$\frac{67}{320}=0.8^t$
take the ln of both sides
$ln( \frac{67}{320})=ln(0.8^t)$
using the property that $ln(a^b)=b(ln(a))$
$ln( \frac{67}{320})=t(ln(0.8))$
divide both sides by ln(0.8)
$\frac{ln( \frac{67}{320}) }{ln(0.8)} =t$
use calculator
7.00728=t
so in about 7 years

Determine whether each pair of segments is congruent

Dafna1 [17]

They are both labeled as 3 feet, so both must be equal, unless you doubt the labeling. Unless that is so, then both segments are equal.
