Answer:
1/4 or 25%
Step-by-step explanation:
Let's see, we want to know probability of an event in which we roll two even numbers.
"We know that probability is defined as number of desired outcomes divided by all possible outcomes"
e - even number
o - odd number
our desired outcome: (e, e) total of 1
all possible outcomes: (e, e), (e, o), (o, e), (o,o) total of 4
that gives us 1/4

<u>the correct question is</u>
The denarius was a unit of currency in ancient rome. Suppose it costs the roman government 10 denarii per day to support 4 legionaries and 4 archers. It only costs 5 denarii per day to support 2 legionaries and 2 archers. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?
Let
x-------> the cost to support a legionary per day
y-------> the cost to support an archer per day
we know that
4x+4y=10 ---------> equation 1
2x+2y=5 ---------> equation 2
If you multiply equation 1 by 2
2*(2x+2y)=2*5-----------> 4x+4y=10
so
equation 1 and equation 2 are the same
The system has infinite solutions-------> Is a consistent dependent system
therefore
<u>the answer is</u>
We cannot solve for a unique cost for each soldier, because there are infinite solutions.
Answer:
512
Step-by-step explanation:
The sequence is doing the number times 2, so 4 times 2 equals 8,
8 x 2 = 16, ect
If you do this enough, you will get 512 as the 8th term.
