The program is given below:-

Explanation:

100 If, Load X /Load the first value

101 Subt Y /Subtract the value of Y, store result in AC

102 Skipcond 400 /If AC=0 (X=Y), skip the next instruction

103 Jump Else /Jump to Else part if AC is not equal to 0

104 Then, Load X /Reload X so it can be doubled

105 Add X /Double X

106 Store X /Store the new value

107 Jump Endif /Skip over the false, or else, part to the end of if

108 Else, Load Y /Start the else part by loading Y

109 Subt X /Subtract X from Y

10A Store Y /Store Y-X in Y

10B Endif, Halt /Terminate program (it doesn't do much!)

10C X, Dec 12 /Assume these values for X and Y

10D Y, Dec 20

First you have to add up all the quantities sold from January to June.

14,000+18,000+13,000+19,000+21,000+14,000= 99,000

now you must divide the total sum by the number of months, in this case 6.

99,000:6= 16,500.

To find the mean add up all those numbers and divide them by 6. to find the median line all the numbers up from biggest to smallest and find the one in the middle. for example 12345, 3 is the median because it is the middle number. the mode is 14000 because it is the most common number. it is seen twice.

im not sure about the second one but i think it is 1 hour and 36 min. 18 miles in one hour going 18 miles and hour and 36 min going 2 miles per hour for 18 miles because 18 times 2 is 36. i then added 1 hour and 36 min together.
