Answer: Add all the absolute deviations and divide by number of swimmers.
Step-by-step explanation:
To find the mean absolute deviation of any data we need to follow the following steps:
- Start by finding the mean of the data set.
- Find the absolute value of the difference between each data value and the mean.
- Find the sum of the absolute values of the differences.
- Divide the sum of the absolute values of the differences by the number of data values.
We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."
Answer: $64
Step-by-step explanation:
Given: The part of money he spent =3/4
Let the total money Otto has be 'x'.
Then according to the question, we have

Multiply 4 on both the sides, we get

Divide 3 on both the sides, we get

Hence, the money he had before he bought the game = $64
Answer:
n = 25/2
Step-by-step explanation:
First, you would want to subtract 7 from both sides of the equation. That would cancel the 7s out and 12-7 = 5. So now the equation looks like this: 2/5n = 5. Next, you would multiply both sides by 5/2, which is the reciprocal of 2/5. Now you have n= 5*(5/2). Lastly, you would just want to multiply 5*5 to get 25 and the 2 will just stay the same. So n = 25/2.
Answer:
Step-by-step explanation:
Given
sunny day speed= s mph
Rainy day speed=s+1 mph
Derek average speed =2.8 miles/hr
s<2.8<s+1
so on sunny day speed must be 2 mph
and on rainy day speed must be 3 mph

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

Let 


Fraction of distance traveled on sunny weather
