Part a: which point represents the origin? (2 points)

part b: starting from the origin, explain how to plot the following three points accurately:

(−1, 1)
(1, −1.5)
(2, fraction 1 over 4)

A) (0,0) is the origin

B) (1, -1)... Go right on the X-Axis to 1. Then go down on the Y-Axis to -1. That will be your first point.

(-1, 1.25) Go left on the X-Axis to -1. Then go up on the Y-Axis to 1.25. That will be your second point.

Finally, (-2, 3/4) Go left on the X-Axis to -2. Then go up to 3/4 on the Y-Axis. That will be your final point.

Step-by-step explanation:

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Binomial approximation to normal.

The binomial probability distribution has parameters n, p and q.

If

and , you can use the normal approximation.

1. n = 24, p = 0.85, q = 0.15

So no.

2. n = 15, p = 0.70, q = 0.30

So no.

3. n = 18, p = 0.90, q = 0.10

No

4. n = 20, p = 0.65, q = 0.35

Yes
