Answer:

65,279,520,000   i hope this helps!   :)

Step-by-step explanation:

69 * 60 = 4140   number of minutes in an hour

4140 * 24 = 99,360   number of hours in a day

99,360 * 8,760 = 870,393,600   number of hours in a year

870,393,600 * 75 = 65,279,520,000  number of years

an average of 65,279,520,000 heart beats in 75 years

Find the MAD for this set of data.
Nostrana [21]

Answer:

Hence MAD=0.8

Step-by-step explanation:

<u>MAD-</u>

MAD is also known as Mean Absolute Deviation.

We find MAD by the following steps:

  • Firstly we find the mean of the data
  • Then we subtract each entry from the mean to obtain the deviation
  • Then find the absolute value of the deviation which is also known as absolute deviation.
  • Finally we find the mean of the absolute deviation.

Now we are given a table of the absolute deviation we just need to calculate the mean of the absolute deviation.

The absolute deviation is given as:

1    3    1    0    0    1    0    0    1    1

The mean of this is calculated as:

\dfrac{1+3+1+0+0+1+0+0+1+1}{10}=\dfrac{8}{10}=0.8

Hence, MAD=0.8
