Answer:
(a) Sample mean is 8.639 rad/s
(b) Sample variance is 4.145 rad^2/s^2
(c) Sample standard deviation is 2.036 rad/s
Step-by-step explanation:
(a) Sample mean = 1.375 Hz = 1.375×2π = 1.375×2×3.14159 = 8.639 rad/s
(b) Sample variance = 0.105 Hz^2 = 0.105×(2π)^2 = 0.105×4π^2 = 0.105×4×3.1415^2 = 4.145 rad^2/s^2
(c) Sample standard deviation = 0.324 Hz = 0.324×2π = 0.324×2×3.14159 = 2.036 rad/s
Well first you have to figure out how many feet are in a yard. Answer is 3 then minus 3/4 or 75% which will give you 2.25 feet. Then do
1 / 2 of (2.25 feet) = 1.125 feet.
3.12 × 104. 3.12E4 = 3.12 × 10 × 10 × 10 × 10 = 31,200 ...
