Variance= 4.2
Standard deviation = 2.12
Answer:
15
Step-by-step explanation:
Simply subtract the smaller number from the bigger number, and divide by 2. Or add the two numbers together and divide by 2.
10I^2/3
This is the answer
You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:
y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

The common difference, d, is 5 and the starting value, a, is 2.
Filling this in the form of

<span>you get
