Answer:

It intersects the x-axis at x = 10

Step-by-step explanation:

Step 1: Find slope <em>m</em>

m = (5 - 1)/(5 - 9)

m = 4/-4

m = -1

y = -x + b

Step 2: Find <em>b</em>

5 = -5 + b

b = 10

Step 3: Rewrite equation

y = -x + 10

Step 4: Find <em>x</em> when <em>y</em> = 0

0 = -x + 10

-10 = -x

x = 10

So the graph crosses the x-axis at 10.

Adding a constant offset to the data does not change its variance. Scaling it, or applying a non-linear function will change the variance.


2. A
For a given number on the 3rd die, the first two dice can match it 11 ways, or have two numbers that match in 5 additional ways. Thus probability of 2 or more numbers being the same is 6*16/216 = 4/9.
