Answer:
The answer to your question is There is no solution, the lines are parallel.
Step-by-step explanation:
Data
Equation 1 x + y = 2
Equation 2 x + y = -1
Solve for y
Equation 1 y = -x +2
y = - x + 2
Equation 2 y = - x - 1
See the graph below
These lines do not cross, so there is no solution. They are parallel.
If the lines have crossed, there would be a solution.
Answer:
<u>25%</u> is the percent error.
Step-by-step explanation:
Given:
The world's largest marathon, The New York City Marathon, is held on the first Sunday in November each year. Between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
Now, to find the percent error.
As given, between 2 million and 2.5 million spectators will line the streets to cheer on the marathon runners.
<em>The actual measure</em> = 2 million.
The estimated measure = 2.5 million.
<em>So, the error</em> =
Now, to get the percent error:
Therefore, 25% is the percent error.
Answer: There are 1820 sets of four marbles other than lavender.
Step-by-step explanation:
Since we have given that
Number of red marbles = 3
Number of green marbles = 5
Number of lavender marbles = 1
Number of yellow marbles = 2
Number of orange marbles = 6
So, Total number of marbles = 3 + 5+ 1 + 2 + 6 = 17
We need to find the sets of 4 marbles other than lavender.
so, Number of total marbles other than lavender becomes = 17 -1 =16
Number of marbles in a set = 4
So, Number of ways becomes
Hence, there are 1820 sets of four marbles other than lavender.
