Answer:
When x1 and x2 decrease 4 units, y decreases by 20 units
Step-by-step explanation:
The regression model is
We have to calculate y for a decrease of 4 units in x1 and x2. For this we have to calculate the variation of y in function of x1 and x2.
As it is a linear regression model, we have:
For a variation in 4 units of x1 and x2, we have
Answer:
I think the answer is B.
Step-by-step explanation:
Answer:
Scalene
Step-by-step explanation:
With this question, it's best to draw it out or we can use process of elimination.
We can rule out Right as the triangle is already obtuse (it can't be both).
We can rule out Equilateral as all the sides are not equal.
We can also rule out Isosceles as this triangle requires 2 sides to be equal, which clearly, they aren't.
Therefore, we are left with Scalene (C) which is your answer.
A scalene triangle has no identical sides or angles, and can be obtuse, right or acute.
