Answer:
Step-by-step explanation:
Just multiply the first equation by -1 and then add them together to find x. Should look something like
-2x - y = -7
5x + y = 9
--------------------
3x + 0 = 2
x = 2/3
Now back substitute using either equation to find y. I'll use the first:
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
Answer:
x=2/3
y=17/3
Answer:
None
Step-by-step explanation:
Because mode is a set of data values is the value that appears most often. If there is no data value or data values that occur most frequently, we say that the set of data values has no mode.
YES IT IS!!
Work:
EQ: y= -x + 4
x= -6
y= 10
y= -x+4
1. 10= -(-6)+4
2. 10= +6+4
3. 10= 10
A.) The completed table is in the attached picture.
Per capita calculation steps Step 1: Per capita = MV Deaths / Population
Step 2: Convert to Scientific notation
Step 3: Round-off to hundredths (2nd digit from the right of decimal place)
Per 100K people calculation steps Step 1: Per 100K people = MV Deaths / Population * 100, 000
Step 2: Round-off to tenths (1st digit from the right of decimal place)
B) I used my completed table (attached picture)
Therefore,
Indiana has the worst rate with 11.6 MV Deaths per 100K People
C) Again, I used my completed table (attached picture)
Therefore,
Illinois has the best rate with 7.3 MV Deaths per 100K People
