Answer:
a) Median: 9
b) Range: 5
c) Mode: 7
Step-by-step explanation:
The median is the number in the middle.
First, you put the numbers in order: 7, 7, 7, 8, 10, 11, 12, 12
The middle of this is 8 and 10, so you plus them and divide by to 2, then it gives 9, so the median is 9.
To find the range, you minus the highest number and the lowest number, 12-7=5.
Mode is the most occurring and repetitive number, in this case, 7, because it is written 3 times.
Hope this helps!!!
Answer:
Work done = 1.69 lb-ft.
Step-by-step explanation:
Work required to stretch a spring 2 feet beyond its natural length W = 12 ft-lb
By Hook's law
12 =
12 = 2k
k = 6 lb per feet
Now we have to find the work done to stretch the spring 9 inch or feet beyond its natural length.
We again use the Hook's law.
lb-ft
Therefore, work done to stretch the spring 9 in. beyond the its natural length will be 1.69 lb-feet.
