Answer:
Option C
Step-by-step explanation:
In the matrix, the determinant is the difference between the opposite elements multiplied.
So, the opposite elements multiplied will give us:
=> ad,bc
The difference is
=> ad-bc
Answer:
5 to 6 or 30 to 36
Step-by-step explanation:
15/3=5, 18/3=6, 15*2=30,18*2=36
Using a calculator, it is found that the correlation coefficient for this data is given by:
B. -0.901.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
To find the coefficient, which has symbol r², we input in a calculator the values of x and the values of y, hence:
r² = -0.901.
Which means that option B is correct.
