Answer:
It is given that ratio of Means to Mean absolute deviation(MAD) of two data sets are 3.4.
Mean is sum of all the observation divided by number of observation.
MAD can be calculated by
1. Find the mean of the data set.
2. Subtract each value of data set from the mean,and take the modulus value.
3. Find the mean of new data set.
Now, consider the two data sets.
A={2,4,6,8,10}
B={6.8,13.6,20.4,27.2,34}
The two data set , have ratio of means to MAD is equal to 3.4.
Which shows, that two data set are different.
Option (C) : They are different is true.
than times 4 times the
number. Find the number.
Answer:
18
Step-by-step explanation:
Let's make this information into an equation.
We'll use 'x' whenever the problem says "a number".
Equation:
5x + 18 = 36 + 4x
How did I get to this equation?
Now, let's solve.
Solve:
5x + 18 = 36 + 4x
Subtract 18 on both sides:
5x + 18 = 36 + 4x
-18 -18
5x = 18 + 4x
Subtract 4x on both sides:
5x = 18 + 4x
-4x -4x
x = 18
Therefore, "the number" is 18.
