Answer:
The standard deviation for this distribution is 0.8660.
Step-by-step explanation:
For each coin toss, there are only two possible outcomes. Either it is heads, or it is tails. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The standard deviation of the binomial distribution is:
In this problem, we have that:
In each toss, heads or tails are equally as likely, since the coin is fair. So 
Three throws, so 
What is the standard deviation for this distribution?
The standard deviation for this distribution is 0.8660.
All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).
Example: factors of 12
12 ÷1 = 12
12÷ 2 = 6
12÷3= 4
12÷4 = 3
12÷6=2
12÷12 = 1
= {12,6,4,3,2,1}
Composite Number/ Its Factors
4 = {1,2,4}
6 = {1,2,3,6}
8 = {1,2,4,8}
9 = {1,3,9}
10 = {1,2,5,10}
12 = {1,2,3,4,6,12}
14 = {1,2,7,14}
15 = {1,3,5,15}
16 = {1,2,4,8,16}
18 = {1,2,3,6,9,18}
20 = {1,2,4,5,10,20}
21 = {1,3,7,21}
22 = {1,2,11,22}
24 = {1,2,3,4,6,8,12,24}
25 = {1,5, 25}
Hope it helps!

Answer:
a=8b
Step-by-step explanation:
To do this we just need to isolate a
so we can multiply the equation by b
then we will get
a=8b
$310 dollars because after it res and decreased it gained $.10 and 100 x 3 is 300 so thats before you calculate how much it rose so .10 x 100 is 10 so add that to 300 and you get 310
