Answer:

10% probability that each sample of size 3 is selected

Step-by-step explanation:

Each sample has the same probability of being selected.

There are 10 samples.

This means that the probability of each sample being selected is:

1/10 = 0.1

10% probability that each sample of size 3 is selected

Which equation is a point slope form equation for line AB ? y+1=32(x−1) y+1=−32(x−1) Four-quadrant Cartesian graph with integer
fenix001 [56]

Answer:

The second option is correct. The point slope form of AB is y+1=\frac{-3}{2}(x-1).

Step-by-step explanation:

The given points are A(-3,5) and B(1,-1).

Slope of a line is

m=\frac{y_2-y_1}{x_2-x_1}

Slope of AB is

m=\frac{-1-5}{1-(-3)}

m=\frac{-6}{4}

m=\frac{-3}{2}

The point slope form of a line is

y-y_1=m(x-x_1)

Where, m is slope of the line.

Case 1: The slope of the line is \frac{-3}{2} and the point is (-3,5). The point slope form of AB is

y-5=\frac{-3}{2}(x+3)

Case 1: The slope of the line is \frac{-3}{2} and the point is (1,-1). The point slope form of AB is

y+1=\frac{-3}{2}(x-1)

Therefore the point slope form of AB is y+1=\frac{-3}{2}(x-1). Option 2 is correct.
