A. She can multiply the bottom equation by -4 and then add the equations to solve for h.

-4g - 15h = -17

4g - 20h = -52

Add them to get

-15h = -17

-20h = -52

From here, you can solve for h.

Answer:

The standard deviation of the age distribution is 6.2899 years.

Step-by-step explanation:

The formula to compute the standard deviation is:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

The data provided is:

X = {19, 19, 21, 25, 25, 28, 29, 30, 31, 32, 40}

Compute the mean of the data as follows:

$\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}$

$=\frac{1}{11}\times [19+19+21+...+40]\\\\=\frac{299}{11}\\\\=27.182$

Compute the standard deviation as follows:

$SD=\sqrt{\frac{1}{n}\sum\limits^{n}_{i=1}{(x_{i}-\bar x)^{2}}}$

$=\sqrt{\frac{1}{11-1}\times [(19-27.182)^{2}+(19-27.182)^{2}+...+(40-27.182)^{2}]}}\\\\=\sqrt{\frac{395.6364}{10}}\\\\=6.28996\\\\\approx 6.2899$

Thus, the standard deviation of the age distribution is 6.2899 years.

Step-by-step explanation:

The diameter of the circle is 4 inches so its radius r is 2 inches. The area of the circle is

$A = \pi r^2 = \pi(2\:\text{in})^2 = 12.57\:\text{in}^2$

The circumference C of the circle is

$C = 2\pi r = 2\pi(2\:\text{in}) = 12.57\:\text{in}$
