Answer:
1.8
Step-by-step explanation:
Slope: 1.8
Equation of the line: y=1.8x-2.6
Answer:
The coefficient of squared term is 1/9
Step-by-step explanation:
The vertex of parabola is (2.-3)
We know the vertex form of a standard parabola

Plugging values of h and k, h= 2, k = -3

Now, x=5, y=-2




Thus, the coefficient of squared term is 1/9
The hinge theorem. Just think of the two sides being connecting by a "hinge"
Answer:
B. Systematic Random Sampling
Step-by-step explanation:
The process of systemic random sampling involves randomly selecting the starting point but the succeeding points will be based on the interval in between each point. The interval is computed by dividing the population by the sample size.
Answer:
-20
Step-by-step explanation:
y = 4x + b
-4 = 4(7) + b
-32 = b
y = 4x -32
r = 4(3) - 32
r = -20
