Answer:
6 - 4i
Step-by-step explanation:
-4 + i = 10 - 5i
<u>+4 +4 </u>
i = 14 + 5i
<u>-5i -5i </u>
-4i = 14
i = -3.5
Answer:
42
Step-by-step explanation:
5 * 4 + (6 / [ 2 + 1 ] ) *11
5 * 4 +2 * 11
20 +2 * 11
20+ 22
42
Answer: 
Step-by-step explanation: In some cases you must apply the exponent rule, simplify, or multiply them together to get your answer.
Correlation coefficient helps us to know how strong is the relation between two variables. The strength of the model is a strong positive correlation.
<h3>What is the correlation coefficient?</h3>
The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
- 1 indicates a strong positive relationship.
- -1 indicates a strong negative relationship.
- A result of zero indicates no relationship at all, therefore, independent variable.
Hence, the strength of the model is a strong positive correlation.
