Answer:
The best estimate of the solution ordered pair from the graph is 
.
Step-by-step explanation:
See the attached graph to this question.
The graph of two straight lines are shown in the graph.
Now, the two straight lines intersect on the x-axis, so the solution ordered pairs should have y-value equals to zero.
But, there are two ordered pairs with y-value zero and they are and 
.
The best estimate of the solution ordered pairs from the graph is .
So, this is the solution. (Answer)
Given the table below which lists the masses and volumes of several pieces of the same type of metal.<span>
From the table the ratio of the mass to the volume of the metal of mass 34.932 is 34.932 / 4.1 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 47.712 is 47.712 / 5.6 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 61.344 is 61.344 / 7.2 = 8.52
</span><span><span>the ratio of the mass to the volume of the metal of mass 99.684 is 99.684 / 11.7 = 8.52
</span>MASS (grams) VOLUME (cubic cm.)
34.932 4.1
47.712 5.6
61.344 7.2
99.684 11.7</span>
Since the ratio of the various masses to the volume of the metals is the same, so there is a relationship between the mass and the volume of the piece of metal.
If the volume of a piece of metal is 15.3 cubic cm, then the mass of the metal is given by 15.3 * 8.52 = 130.356 grams.

Answer:
0.195
Step-by-step explanation:
Given:
For ; sample size, n = 9 ;
Standard Error (S. E) = 0.39
S. E = σ / sqrt(n)
σ = standard deviation
0.39 = σ / sqrt(9)
σ = 0.39 * 3
σ = 1.17
Therefore, For n = 36
S. E = 1.17 / sqrt(36)
S.E = 1.17 / 6
S.E = 0.195
Answer:
To find increase/decrease, divide the starting number by the ending number.
<u>40 to 20</u>
20 ÷ 40 = 0.5
0.5 can be represented by 50%.
<u>20 to 40</u>
40 ÷ 20 = 2
2 can be represented by 200%. This is why decreasing 40 to 20 is a 200% increase. In the wording, it says it's a 100% increase. That would be 20 plus 20 times 1 (which is the same as 100%) which is 40.
