The probability of a head or tail upon flipping is 50-50. THe asnwers are as followsL
a. {HHH, HHT, HTT, TTT, TTH, THH, HTH, THT}b and c. p = 3C3 * 0.5^3 = 0.125d. from a, p = 3/8 = 0.375e. from a, p = 3/8 = 0.375f. 0.875
Answer:
a. 25.9% b. $.76 per pound
Step-by-step explanation:
For part a. the formula for percent decrease is
% dec = 
We are solving for % dec. Filling in:
% dec = 
simplifies to
% dec = 
which gives us, rounded to one decimal place:
% dec = 25.9%
For part b. we are going to use that percent decrease and fit it into a new equation to solve for the new price of tomatoes when we know the original price. Filling in:
which could be written instead as
Now you can see what will happen on the right when we divide by 100...they cancel out. That looks like this, when we divide both sides by 100, as we must because this is an equation:
Simplifying on both sides:
Now we will multiply both sides by 1.03:
.26677 = 1.03 - new and
-.76323 = -new so
the new price is .76 per pound
1) 1 Quarter, 2 Dimes, 2 Nickles, 10 Pennies
2) The ninth floor is 3 times as far from the ground as the third (9/3)
3) That number is 20 (20/2 = 10, 20*2 = 40, 40-10 = 30)
4) 1 Bracelet is $9 (If 2 rings are $12 then 1 ring will be $6. $36 - $18 = $18 2 bracelets = $18)
5) Addie weighs 4oz Missy weighs 14oz Corky weighs 8oz(A + M = 18, M + C = 22, A + C = 12. )
