Answer:
2.25
Step-by-step explanation:
There are ten combihations of the 5 boards taken 2 at a time. The values of x for each combination are as follows:
(1 ,2), x = 2; (1, 3), x = 1; (1,4), x = 1; (1, 5), x = 1; (2, 3), x = 1; (2, 4), x = 1; (2, 5), x = 1; (3,4), x = 0; (3, 5), x = 0; (4, 5), x = 0.
The mass function of x can be expressed as follows:
P(x = 0) = 0.3.
P(x = 1) = 0.6.
P(x = 2) = 0.1
The answer is c have a good day
Answer:
•0.5
Step-by-step explanation:
We'll assume the dilation was done at the origin point, so it was done evenly.
Since the k point went from (10,0) to (5,0), we know it was reduced... so the scale factor has to be below 1. A scale factor means the size wasn't changed and a dilation/scale factor larger than 1 means it was enlarged.
So, we take the new X-value (5) and divide it by the original X-value (10).
Scale factor = 5/10 = 1/2... so 0.5
