Rise over run would be a thing to start with since you use graphs<span />

Ok so follow the steps. If you have to ask for further info or watch a couple instructional videos but I will help you out on number 1 if i can. Ok so the formula for a slope is rise/run. The rise is the Y-axis and run is the X-axis. you choose point along the line so the points I am going to choose are. (2, 3) and (-3, -2). So now we take and add the Y coordinates (3 and -2) so: 3+ (-2) = 1 and now we take and add the X coordinates ( 2 and -3) so: 2+ (-3)= (-1). Now if i am correct the equation now 1/(-1) which would come out to be the slope of 1 i believe.

Answer:

Mean: $\bar x = 40.61$

$Median =40.2$

$Mode = 43.4$

Step-by-step explanation:

Given

See attachment for data

Solving (a): The mean

Mean is calculated as:

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

From the attached:

$n = 14$

So, the mean is:

$\bar x = \frac{43.4+43.4+43.4+43.1+43.2+40.2+40.2+40.1+40.3+39.44+39.17+38.03+38.19+36.45}{14}$

$\bar x = \frac{568.58}{14}$

$\bar x = 40.61$

Solving (b): The median

$n = 14$ ; this is an even number. So, the median is:

$Median = \frac{1}{2}(n+1)$

$Median = \frac{1}{2}(14+1)$

$Median = \frac{1}{2}(15)$

$Median = 7.5th$

This implies that the median is the average of the 7th and 8th item.

Next, is to order the data (in ascending order): <em>36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.</em>

The 7th and 8th items are: 40.2 and 40.2

The median is:

$Median = \frac{1}{2}(40.2 + 40.2)$

$Median = \frac{1}{2}*80.4$

$Median =40.2$

Solving (c): The mode

43.4 has the highest number of occurrence.

So:

$Mode = 43.4$
