Answer:

The plot is made up of a rectangle and a trapezium:

Total area = area of rectangle+area of trapezium

${ \tt{area = 2(l + w) + \frac{1}{2} h(a + b)}}$

substitute:

${ \tt{area = 2 (300 + 196) + \frac{1}{2} (300 - 196)(480 + 300) }} \\ \\ { \tt{area = 992 + 40560}} \\ \\ { \boxed{ \boxed{ \tt{ \: \: area = 41552 \: \: {m}^{2} \: \: }}}}$

Answer: See below

Step-by-step explanation:

a) There is a correlation between the number of employees in the plant and the number of products produced yearly. Specifically, a positive correlation exists because, as we can see on the table, as the number of employees increases, the number of products also increases. And the rate of increase is constant.

b) Let the function be: y = mx + b

When x = 0; y = 120

So:

120 = 0 + c

c = 120

Now the slope:

$\text { Slope }=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{200-120}{10-0}=\frac{80}{10}=8$

Therefore, the equation that best fits the data is y = 8x + 120

c) The slope in the function represents the constant rate of change, meaning that as the number of employees increases by 1, the number of products produced monthly increases by 20. While the y-intercept of the plot, which is 120, indicates the constant number of products, that is to say, when there are no employees, there are still 120 products.
