Mean = (Sum of values)/(Number of values)

$Mean\\ \\ =\frac { 55+62+61+54+68+72+59+61+70 }{ 9 } \\ \\ =\frac { 562 }{ 9 } \\ \\ =62.4\quad mph\quad (1\quad d.p)\\ \\$

Range = Highest Value - Lowest Value

$Range\\ \\ =72-54\\ \\ =18\\ \\$

The graph shows the relationship between the height of a tree and its age in years. What is the unit rate of growth for the tree

xxMikexx [17]

Answer:

The unit rate is 2 feet per year

Step-by-step explanation:

The graph is missing (See attachment)

To determine the unit growth;

First, we have to pick any two corresponding on the x and y axis

When x = 5; y = 10

When x = 1; y = 2

These can be represented as;

$(x_1,y_1) = (5,10)$

$(x_2,y_2) = (1,2)$

Next, is to determine the slope using;

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Substitute values for x and y

$m = \frac{2 - 10}{1 - 5}$

$m = \frac{-8}{-4}$

$m = 2$

<em>Hence, the unit rate is 2 feet per year</em>
