Answer:
x = - 3
Step-by-step explanation:
Solving
= 8
= 2³
= 2³
Since the bases on both sides are equal equate the exponents
- x = 3 ( multiply both sides by - 1 )
x = - 3
Isolate the variable by dividing each side by factors that don't contain the ...
y variable=139x/ 5 2/5-
x variable =5y/139+2/139
Using correlation coefficients, it is found that the measures have a correlation, but it is not strong.
<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.
In this problem:
- Correlation of -0.52 indicates that they have a negative correlation.
- Since |-0.52| < 0.6, the correlation is not strong.
