The coin values don't matter. What does is the fact that each can land on either heads or tails. There are 3 coins, so you would do 3!, or 3 factorial. 3! = 3 * 2 * 1, or 6. Thus, there are 6 possible outcomes.

90,88,88,87,84,95,90,80,98,and 100
Nitella [24]
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100 
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178   178/2=89
Median = 89 

Now in Order to find the mean add up all the numbers and divide by however many numbers their are 
You should get 900 then divide by 10 because their were 10 numbers 

So Median=89 &  Mean=90

a parking lot contains (2 wheels) and cars (4 wheels). There are 35 vehicles and 114 wheels. How many motorcycles amd cars are t
ELEN [110]

Answer:

There are 13 motorcycles and 22 cars

Step-by-step explanation:

Let x represent the number of motorcycles, and let y represent the number of cars.  We can set up a system of equations to solve this...

x + y = 35          (there are a total of 35 vehicles)

2x + 4y = 114      (the total number of tires)

Solve the first equation for either variable...

y = 35 - x

Now substitute that value into the other equation and solve...

2x + 4(35 - x) = 114              (y becomes 35 - x)

Now solve...

2x + 140 - 4x = 114

     -2x = -26

            x = 13               (there are 13 motorcycles)

Now plug that value into either original equation to solve for y...

13 + y = 35

   y = 22    (there are 22 cars(
