Proportional relationship
We know a proportional relationship is when one of the variable is obtained by multiplying the other variable by a constant number.
For example, in an equation it can be represented:
<em>y = 2x</em>
<em />
In a table, we can represent it by
<em />
In a graph,
Answer: all of them
The range is <span>is greater for data set 2.
- This is because it goes from 21-34 in the first set and 12-36 in the second.
The mean is greater for data set 2.
- This is because the first mean is 27.4 and the second is 28.05. </span>
61.8 x 1.7 = 105.06
35.80 x 5.6 = 200.48
Answer:
x= 1
y= -3
Step-by-step explanation:
multiply them to get common factor for y or x:
3(7y+10x=-11)
10(4y-3x=-15)
21y+30x=-33
40y-30x=-150 <em>x's cancel out so solve for y</em>
61y = -183
/61 /61
y = -3 <em> insert y into either equation and solve for x</em>
<em />
<em>4(-3) -3x=-15</em>
<em>x = 1</em>
Answer:
2/2
Step-by-step explanation:
There are only red and green jump ropes so she is for sure going to get a red or green jump rope. If she wants specifically a red or green jump rope her chances are 1/2.
