<span>Answer: Where:
θ = confidence value
n = number of observations
μ = mean
Θ = standard deviation
... then your interval will be:
μ - θΘ/√n ≤ X ≤ μ - θΘ/√n
For some reason they want you to calculate the standard error, which is the Θ/√n section, and I mentioned the 1.96 value, so the above equation simplifies to: μ - 1.96SE ≤ X ≤ μ - 1.96SE</span>
Answer:
t = √1.5/g
Step-by-step explanation:
1/2gt^2 = 3
Divide both sides by 1/2
gt^2 = 1.5
Divide both sides by g
t^2 = 1.5/g
Square root both sides
t = √1.5/g
900/12= 75
780/12= 65
75+65=140
The answer is a
Answer:
(5,0)=x1,y1
(0,3)=x2,y2
so the range will be x1-x2/
