The standard deviation is 1.98. Option A is correct.
The standard deviation formula is given as
where:
- SS is the sum of squares = 200
- n is the sample size = 51
Substitute the given parameters into the formula to have:

Hence the standard deviation is 1.98

Step-by-step explanation:
first one i believe
We can figure this out using the explicit formula.

n represents the term we are looking for.f(1) represents the first term in the sequence, which in this case, is -242.d represents the common difference, which in this case, is -9.
f(n) = -242 + -9(n - 1)
f(n) = -242 - 9n + 9
f(n) = -233 - 9n
Now, we can input 28 for n and solve.
f(28) = -233 - 9(28)
f(28) = -233 - 252
f(28) = -485
The 28th term of the sequence is -485.

Answer:
6 u^4 v^2 (5 y^9 + 4 u^4 v^6)
Step-by-step explanation:
factoring basically means to take out the things that they have in common and put it outside of the parenthesis
when my says something like u^4 it means 4 is an exponent of u
