At a depth of 930 miles (1,500 km), this rock is some 300 times stiffer than at the boundary between the upper and lower mantle, which is about 410 miles (660 km) deep.
The numbers at which <em>f</em> is not differentiable are;<u> -1, and 2</u>
The reason the above list of numbers at which <em>f</em> is not differentiable are correct are given as follows:
<em>Question; Please find attached a graph that can be used to solve the question</em>
- A function is not differentiable at a point where the function has a discontinuity. That is a point on the graph were there is a break in the graph
Therefore, the given graph of <em>f</em> shows that <u>the function is not differentiable at x = -1</u>, the point where the graph has a discontinuity
- A function is not differentiable at a point where the graph of the function has a kink or corner.
The graph of <em>f</em> has a kink at x = 2, therefore, <u>the function is also not differentiable at x = 2</u>

Difference between the mean of the data, including the outlier and excluding the outlier is;
B: 0.93
<h3>Mean average</h3>
Her time in minutes for the given months are;
- January = 41.55 minutes
- July = 36. 38 minutes
- Feb = 42.51 minutes
- Aug = 38.48 minutes
- Mar = 43. 01 minutes
- Sept = 41.87 minutes
- Apr = 39. 76 minutes
- Oct = 51.32 minutes
- May = 37. 32 minutes
- Nov = 42.59 minutes
- June = 35.28 minutes
- Dec = 43.71 minutes
Looking at all the numbers, they largely range from 36 to 44 which means that the outlier is 51.32
Total number of minutes with outlier = 493.78 minutes
Number of months = 12
Thus;
Mean with outlier = 493.78/12
Mean with outlier = 41.15 minutes
Mean without outlier = (493.78 - 51.32)/(12 - 1)
Mean without outlier = 40.22 minutes
Thus;
Difference in both means = 41.15 - 40.22
Difference = 0.93
