Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .
Probability of both = (1/6) x (1/2) .
You do the multiplication.
4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .
Probability of both = (1/3) x (6/11) .
You do the multiplication.
Answer:
5 tractors can plow a square field of side length 1,000 meters in 3.33 hours (3 hours 20 minutes)
Step-by-step explanation:
Let's find out how much each tractor can plow each hour.
per tractor per hour
is the area of the field of side length 1,000 meters
5 tractors can plow
per hour.

<u>Statements</u>
<u>case A)</u> Sara had baked more cookies at the start of the
hours than Liz
The statement is True
we know that
At the start of the
hours Liz has baked
cookies-----> see the graph
Find the number of cookies that Sara has baked for
hours



therefore
Sara had baked more cookies at the start of the
hours than Liz
<u>case B) </u>Sara bakes
cookies each hour
The statement is True
we know that
The number of cookies baked each hour is equal to the slope of the linear equation
The linear equation is

The slope is 
<u>case C)</u> Liz bakes
cookies each hour
The statement is false
Find the slope of the Liz graph
The slope is equal to

Let

Substitute the values


<u>case D)</u> Liz bakes more cookies each hour than Sara
The statement is False
Sara bakes
cookies each hour
Liz bakes
cookies each hour
