Answer: SECOND OPTION
Step-by-step explanation:
Substitute any value of <em>n</em> shown in the table attached into each function given in the options, and observe if you obtain the value of 
shown in the table.
Let's substitute n=1 (According to the table, you need to obtain 
):
<u>For the first option:</u>
<u>For the second option:</u>
THIS IS THE FUNCTION
<u>For the third option:</u>
<u>For the fourth option:</u>
Therefore, the answer is the second option.
Answer:
Option b) r = 0.70
Step-by-step explanation:
We are given the following in he question:
Variables:
x = the number of hours spent studying for a test
y = the number of points earned on the test
- Correlation is a technique that help us to find or define a relationship between two variables.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
- Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
As the number of hours increases, the number of points earned on the test increases. Thus, the two variables are positively correlated.
Thus, the coefficient correlation between two variables can be given by r = 0.70, that shows a moderate positive correlation.
Option b) r = 0.70
I think the answer is right triangles sorry its it wrong
No it is not. One is in hundreths and the other thousandths
the elephant grass should grow 33.75 inches in 9 days.
you take the number of inches it grows times the number of days:
3.75 (aka 3 3/4) times 9 is 33.75.
