Tan(3x) = 1
3x = arctan(1) = pi/4, -3pi/4
x = (pi/4)/3 = pi/12 or (-3pi/4)/3 = -pi/4
Therefore, x = pi/12 or -pi/4

Alexeev081 [22]

Answer:

The 95% confidence interval is (29.54 - 53.46}

Step-by-step explanation:

given data:

$\hat X = 41.5$

Se = 6.1

n = 755

a) best estimate $\hat x = 41.5$

b) at 95% confidence interval

$\alpha = 1- 0.95 = 0.05$

$\alpha /2 = 0.025$

$z_{\alpha/2} = z_{0.025} = 1.96$

at 95% confidence interval for [/tex]\mu[/tex]

$\hat x \pm z_{\alpha /2} \times Se$

$41.5 \pm 1.96\times 6.1$

$41.5 \pm 11.96$

The 95% confidence interval is (29.54 - 53.46}

Contact [7]

Answer:

Step-by-step explanation:

I'm not sure I know what the paper ball situation is, but I can tell you that especially when working with a set formula in physics, math or chemistry (I'd include biology if I knew any biology) that it is a good idea to write down your givens.

The equation you are given is going to fall apart once you know what your givens are and what they do.

I just looked up the Paper Ball Situation. This is a wonderful piece of physics. It immediately opened up all sorts of treasures once they experimenters thought of using tin foil. Givens are a necessity in such an experiment.
