Answer:
a)
P(X = 0) = 5/10
P(X = 5) = 3/10
P(X = 10) = 2/10
b)
E = 0·5/10 + 5·3/10 + 10·2/10 = 3.5
V = 0^2·5/10 + 5^2·3/10 + 10^2·2/10 - 3.5^2 = 15.25
Answer:
The scale factor is <u>5</u>
Step-by-step explanation:
To find the scale factor, we divide 17 by 3.4 to find how much it was enlarged by.
17/3.4 = 5
We do this becuase when finding the scale factor, we take the dilated shape/side length and divide it by the original shape/side length.
