Answer:
Step-by-step explanation:
1) Find the Greatest Common Factor (GCF).
1 - What is the largest number that divides evenly into 
and 
?
It is 
2 - What is the highest degree of 
that divides evenly into and ?
It is 1, since is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3) Simplify each term in parentheses.
4) Factor out common terms in the first two terms, then in the last two terms.
5) Factor out the common term 
.

Answer:
Step-by-step explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.
Circumference = 2 pi r = 20 pi
corresponding to 360 degrees
so an arc of 4pi feet will have a degree measure of 5pi / 20pi * 360 = 1/4 * 360 = 90 degrees
