Answer:
Correlation requires both variables to be quantitative.
Step-by-step explanation:
The correlation coefficient measures the strength of relationship between two quantitative variables. In the given scenario correlation between sex of American workers and their income is computed and indicated that there is a high correlation between them. The sex of American worker is a categorical variable or a qualitative variable while income of American worker is a quantitative variable. The correlation between a quantitative variable and a qualitative variable can't be computed. So, the statement explains the blunder in the given scenario is "Correlation requires both variables to be quantitative".

Answer:
After simplifying we get (x,y) as (1,3).
Step-by-step explanation:
Given:
,

We need to use elimination method to solve the and simplify the equations.
Solution;
Let
⇒ equation 1
Also Let
⇒ equation 2
Now by solving the equation we get;
first we will Add equation 2 from equation 1 we get;

Now Dividing both side by 5 using division property of equality we get;

Now Substituting the vale of x in equation 1 we get;

subtracting both side by 1 using subtraction property of equality we get;

Now Dividing both side by 7 using division property of equality we get;

Hence we can say that, After simplifying we get (x,y) as (1,3).
