We need to test the hypotheses:
The confidence interval for proportion is
.
Here
The z value to be used is 1.96.
The 95% CI is
.
Since 0.5 lies in the interval (0.488,0.543), we cannot reject the null hypothesis with 95% confidence.
Answer:
W = 3
Step-by-step explanation:
2(W - 1) + 8 = 6(2w - 4)
2w - 2 + 8 = 12w - 24
2w + 6 = 12w - 24
6 = 10w - 24
30 = 10w
3 = W

Answer:THe total energy can be found from the maximum kinetic energy since energy is conserved. Kinetic energy is
K = 1/2 mv^2 and v = dx(t)/dt = (0.2)(2*pi/2)cos((2*pi/2)t)
vmax = 0.2*pi m/s when t = 0 so the total energy is
E = 1/2 mvmax^2 = 1/2 m*0.04*pi^2 = 0.1257 J
