Show how to solve for g:
3g - x = rh
Answers
Let me know if its correct! Kinda rushed a bit! I'd wait for someone else to answer just to confirm!
Answer:
g= 1/3 hr + 1/3 x
Step-by-step explanation:
Solving for G
Step 1: Add x to both sides.
3g − x + x =hr+x
3g = hr+x
Step 2: Divide both sides by 3.
3g/3 = hr+x/3
g= 1/3hr + 1/3x
Answer:
[tex] \rm g = \dfrac{1}{3}(rh + x) [/tex]
Step-by-step explanation:
Solve for g:
[tex] \longrightarrow [/tex] 3g - x = rh
Add x to both sides:
[tex] \longrightarrow [/tex] 3g + (x - x) = rh + x
x - x = 0
[tex] \longrightarrow [/tex] 3g = rh + x
Divide both sides by 3:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3} g = \dfrac{1}{3}(rh + x) [/tex]
[tex] \rm \dfrac{3}{3} = 1: [/tex]

A community college announces that the correlation between college entrance exam grades and scholastic achievement was found to be -1.08. On the basis of this you would tell the college that:______
Answers
Answer:
the college should hire a new statistician
Step-by-step explanation:
In statistics correlation is a measure of the linear relationship between two variables.
How closely related the two variables are gives the strength of the relationship.
Positive correlation occurs when an increase in the value of one variable results in an increase in the value of the other.
Negative correlation is when there is an inverse relationship. That is an increase in one variable results in a decrease in the other.
In the given scenario where there is a statistical analysis between exam grades and scholastic achievement, the relationship between them should be a positive one.
The higher the exam grades a student gets the higher his scholastic achievement.
However it is stated that correlation is -1.08. This implies an inverse relationship, which is not correct.
So the college should hire a new statistician who can give more accurate analysis

y>-3x+1
How do I graph this
Answers
Answer:
The graph of y>-3x+1 through the points (0,1) and (1,-2)
Step-by-step explanation:
y=3x+1 is in the slope intercept form
y=mx+b
m = the slope in this case 3
b = the y intercept in this case 1.
Think of b the y intercept as the beginning this is where to start the graph.
So start with (0,1) the y intercept and make the first point at (0,1)
Think of m ( the slope) as the mountain slope, This is the angle of the slope of the line
So in this case go up three on the y axis and over 1 on the x axis.
make the next point at 1 + 3 = 4 for the y value and 0 + 1 = 1 for the x value. Make the next point at ( 1, 4)
Now connect the points. creating the line

Suppose the total number of acres of genetically modified crops grown in developing countries from 2006 through 2012 was changing at the rate of R′(t)=2.613t2−17.7t+41.38 (0 ≤ t ≤ 6). The total number of acres of such crops grown in 1997 (t=0) was 18.1 million acres. How many acres of genetically modified crops were grown worldwide in 2012?
Answers
Answer:
The number of acres of genetically modified crops were grown worldwide in 2012 is approximately 529.39 million.
Step-by-step explanation:
Note: There are mistakes in this question particularly in the years and the rate of change. The question is therefore correctly stated before answering the question as follows:
Suppose the total number of acres of genetically modified crops grown in developing countries from 2006 through 2012 was changing at the rate of R′(t) = 2.613t^2 − 17.7t + 41.38 (0 ≤ t ≤ 6). The total number of acres of such crops grown in 2006 (t=0) was 18.1 million acres. How many acres of genetically modified crops were grown worldwide in 2012?
The explanation to the answer is now given as follows:
From the question, we are given:
R′(t) = 2.613t^2 - 17.7t + 41.38 ................................... (1)
Since t = 0 corresponds to 2006; by counting from 2006 to 2012, it implies that t = 6 corresponds to 2013.
Substituting t = 6 into equation to obtain the rate of change in 2012, we have:
R′(6) = (2.613* 6^2) - (17.7 * 6) + 41.38
R'(6) = 29.248
The number of acres of genetically modified crops were grown worldwide in 2012 can therefore be calculated as follows:
Number of acres grown worldwide in 2012 = Number of acres grown worldwide in 2006 * R'(6) ......................... (2)
Where;
Number of acres grown worldwide in 2006 = 18.1 million acres
R'(6) = 29.248
Substituting the values into equation (2), we have:
Number of acres grown worldwide in 2012 = 18.1 * 29.248 = 529.3888 million
Approximating to 2 decimal places, we have:
Number of acres grown worldwide in 2012 = 529.39 million
Therefore, the number of acres of genetically modified crops were grown worldwide in 2012 is approximately 529.39 million.
