Answer:

n = 0.3

Step-by-step explanation:

To solve the proportion using cross products, we will follow the steps below;

\frac{0.5}{5}  =  \frac{0.03}{n}

Cross - multiply

0.5 ×  n  =  0.03×5

0.5n = 0.15

Divide both-side of the equation by 0.5

\frac{0.5 n}{0.5}   = \frac{0.15}{0.5}

(On the left-hand side of the equation, 0.5 at the numerator will be cancel-out by 0.5 at the denominator leaving us with just n while on the right-hand side of the equation 0.15 will be divided by 0.5)

n = 0.3

Suppose that the mean time that visitors stay at a museum is 94.2 minutes with a standard deviation of 15.5 minutes. The standar
Maurinko [17]

Answer:

94.2 -0.994*3.1 = 91.1186

94.2 +0.994*3.1 = 97.2814

And the 68% confidence interval is given by (91.1186, 97.2814)

Step-by-step explanation:

For this case we know that mean time that visitors stay at a museum is given by:

\bar X = 94.2

The standard deviation is given by:

s= 15.5

And the standard error is given by:

SE = \frac{s}{\sqrt{n}} =3.1

And we want to interval captures 68% of the means for random samples of 25 scores and for this case the critical value can be founded like this using the normal standard distribution or excel:

z_{\alpha/2}= \pm 0.994

We can find the interval like this:

\bar X \pm ME

And replacing we got:

94.2 -0.994*3.1 = 91.1186

94.2 +0.994*3.1 = 97.2814

And the 68% confidence interval is given by (91.1186, 97.2814)

Make cos C the subject of the formula<br> C?= a? + b? - 2ab cos C
lara31 [8.8K]
<h3>Answer:  Choice E</h3>

Work Shown:

c^2 = a^2 + b^2 - 2ab\cos(C)\\\\c^2 + 2ab\cos(C) = a^2 + b^2\\\\2ab\cos(C) = a^2 + b^2 - c^2\\\\\boldsymbol{\cos(C) = \frac{a^2 + b^2 - c^2}{2ab}}\\\\
