Answer:

Step-by-step explanation:
Total number of tiles: 11 (obtained from counting the letters in probability)
Probability of picking the letter "i" the first time:
There are 2 letter "i's", and 11 total options, so the probability of picking an "i" is:

Probability of picking the letter "i" the second time:
We now have one less letter in the bag, as the first letter "i" was not replaced.
This means we now only have 1 letter "i", and 10 total options, so the probability of picking the last "i" is:

When you have two probabilities that are dependant on each other, you multiply them to get the probability of one, given that the other has happened.
Total probability:
Simplify by dividing by 2:

I'm distributing
2x-8=25
(add 8 from both sides)
2x=33
(Divide both sides by 2)
X=16.5
Area = PI x r^2
area = 3.14 x 6^2
area = 3.14 x 36
area = 113.04 square yards
round the answer if needed.
Answer:
Slope of the perpendicular line: 2/3
Step-by-step explanation:
-2y = 3x - 6
y = - 3/2x - - 6/2
y = -3/2 + 3
I believe that the correct measurement in feet is 1.4 x
10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore
half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
