Answer: y = 4
Step-by-step explanation:
To solve, we will isolate the y variable.
Given:
4(y + 4) = 32
Distribute the 4 with multiplication:
4y + 16 = 32
Subtract 16 from both sides of the equation:
4y = 16
Divide both sides of the equation by 4:
y = 4
The answer is 11. 0.22 x 50 is 11.
Using correlation coefficients, it is found that a coefficient of -1 represents a strong negative correlation.
<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.
For this problem, we have a correlation coefficient of -1, hence it means that:
- The relation is negative, as -1 is a negative number.
- The relation is strong, as the absolute value of the coefficient is of 1, which is greater than 0.6.

Answer:12/5
Step-by-step explanation:
First, you multiply 9 x 13 x 10 = 1170 which is the area of the whole triangle
Then, divide that, 1170, by 2 which equals 885.
So your answer (which im pretty sure is correct) 885
Hope i helped pm me for any other problem
