Answer:

$\sigma = 121.53$

Step-by-step explanation:

The population standard deviation

First, calculate the population mean

$\mu = \frac{\sum x}{n}$

This gives:

$\mu = \frac{148+ 329+ 491 +167+ 228+285+ 441}{7}$

$\mu = \frac{2089}{7}$

$\mu = 298.43$

The population standard deviation is:

$\sigma = \sqrt{\frac{\sum(x - \bar x)^2}{n}}$

So, we have:

$\sigma = \sqrt{\frac{(148 - 298.43)^2 + ..........+ (441- 298.43)^2}{7}}$

$\sigma = \sqrt{\frac{103387.7143}{7}}$

$\sigma = \sqrt{14769.6734714}$

$\sigma = 121.53$

If the area of the rectangle is 154 km2, then what is the value of the missing side?

KatRina [158]

Area of a rectangle: length * width

You are given the width, 11 km, so plug in 11 for width and 154 for area in the formula for area of a rectangle and solve for length (x).

x * 11 = 154

rewritten as: 11x = 154

Divide both sides by 11.

x = 14

Your answer is C) 14 km.
