Answer: 10 units²

Step-by-step explanation:

We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.

We can get each triangle's area using the formula $A = \frac{1}{2}bh$

<h3>Left Triangle</h3>

base length - 4 units

height - 4 units

$A = \frac{1}{2}(4)(4)$

$A=\frac{1}{2}(16)$

$A =8\hspace{0.1cm}units^2$

<h3>Right Triangle</h3>

base length - 2 units

height - 2 units

$A = \frac{1}{2}(2)(2)$

$A=\frac{1}{2}(4)$

$A=2\hspace{0.1cm}units^2$

Total = 8 units² + 2 units² = 10 units²

If a sample of 362 customers is taken from a population of 5530 customers,

inysia [295]

Using concepts of <u>sample and population</u>, it is found that the sample variance is representative of 362 and 5530 customers ages, option D.

------------------------

In sampling, the <u>information is taken from a sample</u>, and is used to <u>estimate it for the whole population</u>.

In this problem, we have a sample of 362 and a population of 5530 customers.
The sample variance $s^2$ is calculated from the sample, and used as an estimate for the population variance. Thus, it can be said that it represents both 362 and 5530 customers, and the correct option is D.
