Benito and Tyler are painting opposite sides of the same fence. Tyler has already painted 19 1/2 feet of his side of the fence w

natali 33 [55]

Answer:

Step-by-step explanation:
Let x be the number of minutes after which both sides have equal number of feet painted,
∵ One side of the fence is painted by Benito,
His speed = 15 ft/min
So, the number of feet painted in one side after x minutes = 15x,
Now, second side of the fence is painted by Taylor,
The feet he already painted = ,
Taylor's speed = 11 ft/min
Thus, the number of feet painted in second side after x minutes = ,

Hence, it will take minutes for both sides to have an equal number of feet painted.

Here in this question, we want to calculate the mean absolute deviation of the data.

The first thing we will do here is to calculate the mean;

= (74 + 79 + 76 + 85 + 87 + 83 + 86 + 78)/8 = 81

Now, the next thing to do here is to calculate how far each of the values have deviated from the mean. This can be calculated by subtracting the mean from each individual value;

This is presented in the table on the attachment, please check attachment for this

Afterwards, we find the absolute value of all these subtractions then divide by 8 which is the number of values in the data.

Mean absolute deviation = Sum of all absolute deviations/number of values in dataset
