a manufacturing company produces engines for light aircraft. the graph shows the number of engines produced each year since the company started operations.

Company will produce 149 engines in 9th year.

Step-by-step explanation:

We have been given a graph that shows the number of engines produced each year since the company started operations. We are asked to write a function for the given dot plot.      

We will use two points on the graph to find slope of the line passing through these points. We can see that point (2,60) and (5,99) is on our given graph.

So the slope of the line is 13.

Now we will use point-slope form as:

Upon looking at our given choices, we can see that function is the correct choice.

Now we will substitute to find the engines produced by company in 9th year as:

Therefore, company will produce 149 engines in 9th year.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
