Step-by-step explanation:
The absolute value is 62/3
Answer:
(26.2252 ; 27.3748)
Step-by-step explanation:
The confidence interval is given by :
x ± Margin of error
The margin of error = Zcritical * (σ/√(n))
σ = 7.5 ; n = 654
Zcritical = Zα/2 = 1.96
The margin of error = 1.96 * (7.5/√654) = 0.5748
The confidence interval :
Upper boundary = 26.8 + 0.5748 = 27.3748
Lower boundary = 26.8 - 0.5748 = 26.2252
(26.2252 ; 27.3748)
We are 95% confident that the mean BMI of the entire population will fall in between (26.2252 ; 27.3748)
So the total is 120. You want 1/6 of those.
So do (1/6)*120
You get 20.
YAY
I think it's 2,5,6 because a rational number is a number that can be put in a fraction.
Examples:
3/7 (3 over 7)
-2/5 (-2 over 5)
And 4, which can be put as 4/1 (4 over 1) in fraction form
Answer:
-70
Step-by-step explanation:
If a number is right by a parathesis () then you multiply the number inside the parathesis by the number next to them.
