Answer: The post office is 32 feet tall.

Step-by-step explanation:

We set up a proportion : 10ft/15ft = xft/48ft

In this equation "x" is the height of the post office. After setting up a proportion with the size of the buildings on the top (numerator) and the shadows of each building on the bottom (denominator) we cross multipy to get our equation to find x. We then divide both sides of the equation by 15 to get our answer.

$\frac{10}{15}=\frac{x}{48} \\15x=10*48\\15x=480\\x=32$

Find the equation of the line that passes through the point (−3, −4) and is parallel to the line that passes through the points

Dimas [21]

Answer:

$y = -\frac{1}{3}x - 5$

Step-by-step explanation:

To write the equation of a line use the point slope formula $y - y_1 = m(x-x_1)$ . Find m by using the slope formula with the points.

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{1--3}{-5-7} =\frac{4}{-12} =-\frac{1}{3}$

Since the line is parallel, it will have the same slope.

Substitute m = -1/3 and (-3,-4).

$y --4 = -\frac{1}{3}(x --3)\\y + 4 = -\frac{1}{3}(x+3)\\y +4 = -\frac{1}{3}x - 1\\y = -\frac{1}{3}x - 5$

Given that Henry divided the town into eight regions and randomly chose 10 households from each region in order to survey about traffic concerns. This type of sample is called stratified sampling.

Stratified sampling is a type of sampling method where the researcher divides the population into separate groups, called strata and then, a probability sample (often a simple random sample ) is drawn from each group.
