Answer: 17/2
Step-by-step explanation:
Step 1
Multiply the denominator by the whole number
2 × 8 = 16
Step 2
Add the answer from Step 1 to the numerator
16 + 1 = 17
Step 3
Write answer from Step 2 over the denominator
17/2
=172
This is not hard to simplifi all you need to do is collect like terms because 3 and 2 are like terms we put them together making 3x - 5 because when you have 2 plus you make it into a minus. I hope this helped you.
Answer:
A
Step-by-step explanation:
The formula for the standard error is this:
σM = σ / √N
where
σM is the standard error
σ is the standard deviation
N is the number of samples
So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%
The standard error is 0.0636
3 (1-7) = 3*1+3*-7
I really just used the distributive property for this.
