first, you separate it into two inequalities.then, you determine whether the answer should be a union of sets or an intersection of sets. lastly, solve both inequalities and graph :)
K= 4 because 8-4= 5. Therefore K= 4
Answer:
387.
Step-by-step explanation:
Given : 3-6(z-2)³.
To find : What is value if z = -2.
Solution : We have given
3-6(z-2)³.
Plugging the z = -2
3 - 6( -2- 2)³.
3 - 6( -4)³.
3 - 6 ( -64).
3 + 384.
387
Therefore, 387.
Answer:
I am not one hundred percent sure but I think it is D
Answer:
The correct option is C) r=-0.80
Step-by-step explanation:
Consider the provided information.
Properties of r in a scatter plot:
The value of r is between -1 and +1.
If the value of r is positive then it associated with positive relationship if the value of r is negative it associated with negative value.
The greater value of r would be closely around a straight line(Regardless of sign).
Now consider the provided relation.
The use of regression line is to minimize the distance between projections and real values.
Correlation is inversely proportional to difference between predicted values and actual values.
So for good fit we just need to look for the highest value of r regardless of the sign.
From the provided options the highest value of r=-0.80
Thus, the correct option is C) r=-0.80
