where are you people getting these like lol
V(cylinder)= πr²h
d=2r,
d is diameter, r is radius.
When diameter is tripled, a new diameter D=3d,
new radius R=3d/2=(3*2r)/2=3r
R=3r
V(new cylinder)= πR²h = π(3r)²h=9πr²h
V(new cylinder)/V(cylinder)=9πr²h/πr²h=9
Volume new cylinder 9 times more the volume of old cylinder.
Answer:
95% confidence interval for the mean μ is (6,14)
The Population mean μ lies between ( 6, 14 )
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given random sample 'n' = 1200
95% confidence interval for the mean μ is determined by
Level of significance = 95% 0r 0.05
Z₀.₀₅ = 1.96
= 10 ± 4
Mean of the small sample = 10
95% of confidence intervals are
( 10 ±4 )
( 10 -4 , 10+4)
( 6 , 14 )
95% confidence interval for the mean μ lies between ( 6, 14 )
Answer:
-4.01, -4, -7
Step-by-step explanation:
equation:
-x + 6 ≥ 10
substitute each number for x
- (-3.9) + 6 ≥ 10 = (negatives cancel each other out) 3.9 + 6 = 9.9 ≥ 10 (incorrect)
-4 + 6 ≥ 10 = 2 ≥ 10 (incorrect)
- (-4.01) + 6 ≥ 10 = (negatives cancel each other out) 10.01 ≥ 10 (correct)
- (-4) + 6 ≥ 10 = (negatives cancel each other out) 10 ≥ 10 (correct)
-4.01 + 6 ≥ = 1.99 ≥ 10 (incorrect)
-3.9 + 6 ≥ 10 = 2.1 ≥ 10 (incorrect)
-0 + 6 ≥ 10 = 6 ≥ 10 (incorrect)
- (-7) + 6 ≥ 10 = (negatives cancel each other out) 11 ≥ 10 (correct)
65 millimeters to meters is .065 and you would know this because there's .001 millimeters in 1 meter so with 65 you would move the decimal up 3 spaces o make .065m
