Answer:
A. Miguel has the greatest spread.
B. Considering the middle 50% of the training time, the person with the least spread is Adam.
C. Miguel is inconsistent with the time set for training compared to that of Adam.
Step-by-step explanation:
The spread of a data shows the range of the data.
Using the range to determine the spread of the given data:
A. The range of the two persons can be determined by:
Range = highest value - lowest value
So that:
Adam's range = 106 - 91
= 15
Miguel's range = 105 - 86
= 19
Comparing the range of the two, Miguel has the greatest spread.
B. Considering the middle 50% of the training time;
Adam - 103 105 104 106 100
Miguel - 88 86 89 93 105
Adam's 50% range = 106 - 100
= 6
Miguel's 50% range = 105 - 86
= 19
Considering the middle 50% of the training time, the person with the least spread is Adam.
C. The answers to parts 2(a) and 2(b) shows that; there is a wide variation (much inconsistency) in the time that Miguel spend during training, but a minimum variation in the time spent by Adam during training.

THE LESS THAN SYMBOL SHOULD HAVE A LINE UNDER IT!
Start at 0 and move to point P. To do this, we simply move left 1/8 of a unit. Similarly, we move 1/8 of a unit to go from 0 to point Q
So the distance from P to 0 is the same as the distance from Q to 0.
Therefore, the absolute values are the same
Answer: Choice A) Jay is correct because each point is 1/8 a unit away from 0
Rational between 5.2 and 5.5
5.2 × 10/10 = 52/10
5.5 × 10/10 = 55/10
rational no. b/w them is 53/10 = 5.3
rational because it is in p/q form where q is not zero and p and q are integers.
irrational.no. b/w 5.2 and 5.5
5.20102030405060708090.......
irrational.no because it is non terminating and non recurring
Permutation
Step-by-step explanation:
- Permutation is an example of the mathematics in which item are arranged in different way.
- For example ABC, ACB, BCA, CBA, CAB, BAC etc.
- The order of an arrangement are different in each alphabet.
- The product of number also be defined as in the form of n to 1
- for example : 5*4*3*2*1 = 120
