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:______
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
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?
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.

Find the values of x and y.
Answer:
If you have given an equation, you see the x and y in it. Just taking second equation and think any common factor between x's variable. With common factor, multiply both and you will find the value of y and put it in any equation, you will find the value of X.
2.7x + 3.2x + x Can someone help me I’m stuck on this
Answer:
6.9x
Step-by-step explanation:
2.7x + 3.2x + x = So you combine like terms. Since they all have x after them, they are all like terms so you can add them all together. x = 1
Therefore, your answer is 6.9x
The Connor family earned $87,000 last year and paid 12% in income tax.
How much did they pay in income tax? *
Answer:
10,440
Step-by-step explanation:
12/100=x/87,000
you are trying to solve for x because you want to know what is 12% of 87,000 so you need to cross multiply to get
12 times 87,000 = 100x
1,044,000=100x
then divide by 100 to get
=10,440
Tamika has two bags of trail mix. Each has a combination of 60 pieces of fruit and nuts. Ratio of fruit to nuts in the first bag:3 5 Ratio of fruit to nuts in the second bag:7 10 Which bag has more fruit? Use the ratios to justify your answer. The first bag, because the ratio is greater. The first bag, because the ratio is smaller. The second bag, because the ratio is greater. The second bag, because the ratio is smaller.
Answer:
the second bag because the ratio is greater
Step-by-step explanation:
Bag1
fruits 3 : 5 nuts so 3+5=8 and 60/8=7.5 but 7.5*3=22.5
ratio is 3/5=0.428
Bag2
fruits 7 : 10 nuts so 10+7=17 and (60/17)*7 ≈ 24.7
ratio is 7/10=0.7
Answer:
The second bag, because the ratio is greater.

Show how to solve for g:
3g - x = rh
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]

y>-3x+1
How do I graph this
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
Write an equation of a line that passes through the point (-4, 5) and have a slope of 1/2
Answer:

Step-by-step explanation:
y = mx+ b

x = -4
5 = 1/2(-4) + b
5 = -2 + b
7 = b

A boy was asked to multiply a number by 7/8
instead he divided the number by 7/8 and got the
result 15 more than the correct result The number is?
Answer:
So first you would do 15 x 7/8 which would get you 13.12500 but round it and you would get 13.125 as the original number. If you were trying to get the number it first asked you would do 15 x 13.125 = 196.87500, round that and you would get 196.875.
