Answer:

The formula to find the voltage is:

$v=\sqrt{P*R}$

And the voltage is 4 volts

Step-by-step explanation:

To get the equation of voltage you need to isolate v in one side of the equation. In order to do that, you need to remove the divisor/denominator and its square. How will you do that?

First, multiply both sides with R:

$P*R=\frac{v^{2} }{R} *R$

That would result into removing the divisor R from the right side of the equation:

$P*R=v^{2}$

Next, square-root both sides:

$\sqrt{P*R} =\sqrt{v^{2} }$

That would result in removing the square of v from the right side of the equation:

$\sqrt{P*R} =v$

Thus we get the equation, $v=\sqrt{P*R}$ .

To find out the voltage, simply replace R with 32 and P with 0.5

$v=\sqrt{0.5*32}$

$r=\sqrt{16}$

$r=4$

Thus, the voltage is 4 volts.

Clothing sizes are not standardized across brands. Suppose that a large study of women's size 14 jeans revealed that the mean hi

kenny6666 [7]

Using the z-distribution, we have that:

The mean hip measurement for the random sample of 15 pairs of women's size 16 jeans is of 44.1 inches.

The margin of error is of 0.8 in.

The interpretation is: Mallorie is 99% sure that the mean hip measurement of size 16 jeans is between 43.3 in and 44.9 in.

The first step to solve this question, before building the confidence interval, is finding the sample mean, which is the sum of all observations divided by the number of observations. Hence:

$\overline{x} = \frac{44.5+43.0+46.6+42.9+43.7+43.9+42.4+43.2+43.1+44.4+46.1+44.7+44.4+43.9+44.7}{15} = 44.1$
