Solution
In order to find  greatest to least number, we have to convert the given fractions into decimals.
3  % = 3 + 1/10 = 3 + 0.10 = 3.10%
 % = 3 + 1/10 = 3 + 0.10 = 3.10%
3  % = 3 + 2/5 = 3 + 0.40 = 3.40%
% = 3 + 2/5 = 3 + 0.40 = 3.40%
3  %= 3 + 0.25 = 3.25%
 %= 3 + 0.25 = 3.25%
3  % = 3 + 0.33 = 3.33%
% = 3 + 0.33 = 3.33%
Now we can easily, compare the numbers and write from greatest to least.
3.40%, 3.33%, 3.25%, 3.10%
Greatest to least  = 3 2/5%, 3 1/3%3, 3 1/4%,  1/10%,

Answer:
babala
Step-by-step explanation:
The probability of being a universal donor is 6% (O-negative-blood type). Suppose that 6 people come to a blood drive.
a) What are the mean and standard deviation of the number of universal donors among the 6 people?
b) What is the probability that there are exactly three universal donors?
 
        
             
        
        
        
Answer:
u = 5/4
Step-by-step explanation:
to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.
solution
3=7(4 - 2u)-6u
3 = 28- 14u - 6u
collect the like terms
3 + 14u + 6u = 28
20u = 28 - 3
20u = 25
divide both sides by the coefficient of u which is 20
20u/20 = 25/20
u = 5/4

T=the amount of shirts
12t-20-8t=100
12t-8t=120
4t=120
t=30
So they must sell at least 30 shirts to make $100.
