your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat
grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a  9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee  

1.  c(m) = 33m + f

 33(6) + f = 228

198 + f = 228

f = $30 membership fee  

c(m) = 33m + 30

 2.  at 9 months:  33(9) + 30 = $327

hopefully this helps :)

have a nice day !!

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
