<span>The average length of crocodiles in a swamp is 11.5 feet. if the lengths are normally distributed with a standard deviation of 1.7 feet, find the probability that a crocodile is more than 11 feet long.
solution:
To obtain P(x>11) we first need to obtain the value of the z-score:
z=(11-11.5)/1.7
thus
z=-0.2941
thus
P(x>11)=1-P(z<-0.2941)=1-0.3859=0.6141

OK for this question you need to find out how many more post are needed. If you look at the diagram it shows that one side is 50 feet.  Now there are two sides that will need post, because the barn side need no more.  Now if there are two side both 50 feet, and you need a post every ten feet. How many posts are needed?

How can you use division to find the decimal equivalent of a rational number ?
Naily [24]

Answer:

Rational numbers' decimal representations either finish or repeat a pattern. Divide the top by the bottom, the numerator by the denominator to convert fractions to decimals, and if the division doesn't come out evenly, round off after a specific number of decimal places.
