Answer:
x=34, y=-28, z=-46
Step-by-step explanation:
because opposite angles of parallelograms are congruent: -3y-3=81 => y=-28. because internal angles of quadrilateral sum to 360°: 81+-3(-28)-3+3x-3-2z+7=360 => 3x-2z=194 => z=3/2x-97. because opposite angles of parallelograms are congruent: -2z+7=3x-3. substitute z=3/2x-97: -2(3/2x-97)+7=3x-3 => x=34. z=3/2(34)-97=-46
The estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders
<h3>How to determine the regression equation?</h3>
We have:
- Predictor variables = 3
- Variable 1 = Age
- Variable 2 = Mileage
- Variable 3 = Cylinders
The regression equation is estimated using:
Price = bo +b1 * Variable 1+ b2 * Variable 2 + b3 * Variable 3
Substitute the variable parameters
Price = bo +b1Age+ b2Mileage + b3Cylinders
Hence, the estimated regression equation is Price = bo +b1Age+ b2Mileage + b3Cylinders

Answer:
10 pounds of the $1.50 chocolate were used.
30 - x represents the number of pounds of the 0.90 chocolate used.
Step-by-step explanation:
30 * 1.10 = 1.5x + 0.9 (30 - x)
33 = 1.5x + 27 - 0.9x
0.6x = 6
x = 10
Answer: B) 73
Step-by-step explanation:
Complementary angles are 2 angles which add up to 90.
90 - 17 = 73
