1. B
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.
Answer:
For 
, the group is CLOSED as it a polynomial.
Step-by-step explanation:
Here, the given polynomials are:
Now, a group G is said to be <u>CLOSED UNDER SUBTRACTION</u> if,
a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G
Now, here:
or, 
Also, R(x) is a POLYNOMIAL.
So, R(x) is an Element of group G.
So, the set G of polynomials.
Hence, for the polynomial , it will be a polynomial the group is CLOSED.
Answer:
Annie can make 4 plates with 
apples and 
apricots on each plate.
Step-by-step explanation:
Annie has 8 apples and 20 apricots.
Factor these numbers:
Find GCF(8,20):
Hence, Annie can make 4 plates with apples and apricots on each plate.

Answer:
48pi or ~150.8
Step-by-step explanation:
ok so area = pi * r^2
r = 8
8^2 = 64pi
so 64/4 = 16
16*3 quarters shaded = 48
48pi is the answer
48pi or ~150.8
