Answer:
(5.871 `; 6.127)
Step-by-step explanation:
Given :
Mean = 6
Standard deviation. σ = 0.5
Samplr size, n = 100
Zcritical at 99% confidence = 2.58
The confidence interval :
Mean ± margin of error
Margin of Error = Zcritical * σ / sqrt(n)
Margin of Error = 2.58 * 0.5/sqrt(100) = 0.129
Confidence interval :
Lower boundary = 6.00 - 0.129 = 5.871
Upper boundary = 6.00 + 0.129 = 6.129
(5.871 `; 6.127)
So,
I'm assuming you are asking:
6 tons = x lbs.
The conversion from tons to pounds is:
1 ton = 2000 lbs.
So:
6 tons = 2000 * 6 = 12,000 lbs.
Answer:
-41
Step-by-step explanation:
if you plug -2 everywhere you see an x and 1 everywhere you see a y, and then simplify you get -41
