Answer:
The linear regression model is 
.
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is
Using technology we get
Put a=-2.19 and b=-8.92 in the above equation.
Therefore the linear regression model is .
Answer:
4+i
Step-by-step explanation:
A complex number usually took the form a+bi where a and b are real numbers and 'i' represents an imaginary number. For a quadratic equation, the complex roots for the root of a quadratic equation took the form known as complex conjugates. The complex conjugates are formed by changing the sign of the imaginary part.
SO, if a quadratic equation has 4-i as a solution, the other solution must be 4+i.
Answer:
8n - 3.9
Step-by-step explanation:
Given
- (- 8n + 3.9 ) ← multiply each term in the parenthesis by - 1
= 8n - 3.9
Answer:
Step-by-step explanation:
So this is an isosceles triangle so the other angle must be x too.
So:
x+x+40 = 180
2x+40 = 180
2x = 140
x = 70
