Answer:
Option C) a positive correlation.
Step-by-step explanation:
We are given the following in the question:
" People who tend to score low on one variable tend to score low on another variable."
Correlation:
- Correlation is a technique that help us to find or define a linear relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity or decrease in one quantity leads to decrease 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.
Since, for the given case with decrease in one variable other also decreases, thus, it is an example of positive correlation. Thus, the correlation coefficient cannot be less than or equal to zero.
Thus, the correct answer is
Option C) a positive correlation.
Answer:
See below
Step-by-step explanation:
Not sure what you are asking....do you want to know what y is when x = -2 and the equation = 6 ?
3 xy^2 + 4x = 6 or is that 3 xy^(-2) + 4x = 6
Could use some serious editing of your question if you are able ....
Answer:
98.25
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Convert 
= ∛(27⁴) = 81
Step 2: Convert 
= 16
Step 3: Convert 
= 1.25
Step 4: Combine
81 + 16 + 1.25
97 + 1.25
98.25
Answer:
Decimal: 0.09
Reduced fraction: 
Step-by-step explanation:
To find the decimal form of a percentage, we solve a rule of three problem.
In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.
When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too. In this case, the rule of three is a cross multiplication.
When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease. In this case, the rule of three is a line multiplication.
Percantage problems are an example of direct rule of three.
100% is 1 decimal. What is the decimal of 9%?
So:
100% - 1
9% - x
Reduced fraction :
The numerator is the percentage, the denominator is 100%. So
Answer: 2√5-3√7+24
