An​ alligator's tail​ length, T, varies directly as its body​ length, B. An alligator with a body length of 4.5 feet has a tail
Amiraneli [1.4K]
If and only if it is a proportional relationship, the problem can be solved by creating a proportion of B1/T1=B2/T2. This can also be expressed as 4.5/3.5=5.4/x given the values. You must cross multiply, so 4.5x=3.5(5.4). This simplifies to x=4.2. So, the tail length would be 4.2 feet.

Hope this helps.

Max tossed a fair coin 3 times. What is the probability of getting heads in the first two trials and tails in the last trial?  
Whitepunk [10]
When you toss a coin 3 times here is what can happen:
H=heads
T= Tails
HHH                        TTT
<u>HHT</u>                        TTH
HTH                        THT
HTT                        THH
Since 8 things can happen and only one of them is what you want, the probability is 1/8
Another way to think about it is each toss has 1/2 of coming up as you want it to.
Three tosses are 1/2 x 1/2 x 1/2 which is 1/8
