Answer:
Option B. is correct
Step-by-step explanation:
Given: The regression equation is y = 1.73 x + 0.39
To find: number of representatives for Oregon, which has a population of about 3.3 million
Solution:
The regression equation determined the specific relationship between a dependent variable and one or more independent variables.
To find number of representatives for Oregon, which has a population of about 3.3 million, put 
in the regression equation is y = 1.73 x + 0.39
So, 6 representatives for Oregon has a population of about 3.3 million
Option B. is correct
We need to find the principal amount on an interest rate of 13% where the end of year payment is $5043.71.
The original amount is 
.
i = Interest rate = 13%
n = Compounding period = 4 years
E = End of year payment = $5043.71
The required formula is
![P=\dfrac{E[1-(1+i)^{-n}]}{i}\\\Rightarrow P=\dfrac{5043.71[1-(1+0.13)^{-4}]}{0.13}\\\Rightarrow P=\$15002.37](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BE%5B1-%281%2Bi%29%5E%7B-n%7D%5D%7D%7Bi%7D%5C%5C%5CRightarrow%20P%3D%5Cdfrac%7B5043.71%5B1-%281%2B0.13%29%5E%7B-4%7D%5D%7D%7B0.13%7D%5C%5C%5CRightarrow%20P%3D%5C%2415002.37)

Answer: 8
Step-by-step explanation:
Given the bar graph above, the difference <span>in monthly electric cost appear to be great because of the choice of scale.
In scaling, the narrower the intervals of the axis, the larger the graph and the more highlighted the relative difference between the components of the graph.
Conversely, the wider the </span><span>the intervals of the axis, the smaller the graph and the less
highlighted the relative difference between the components of the graph.
Therefore, to make </span><span>the difference in monthly electric cost appear not to be as great</span>, we widden the intervals on the y-axis.
i.e. '<span>The interval on the y-axis could be changed to count by 20s.'</span>
Answer:
j=12
Step-by-step explanation:
Question: <u>j/4-10/3=-1/3</u>
1) Add 10/3 to both sides:
j/4=3
2) Multiply both sides by 4:
j=12
