Tina says that 6:8 is equivalent to 36:64 . what did tina do wrong!

She simplified it wrong because you're only supposed to simplify it with the same numbers. For example: simplify 2/4. You divide it by 2/2. You do the same and it will be correct.

Answer:

Explanation shown below

Step-by-step explanation:

For 6:8 to be equal to another fraction, Tina needed to MULTIPLY both top and bottom by the same number, NOT RAISE TO A POWER.

Multiplying by any number (both numerator & denominator) would make the other ratio equivalent.

Taking "Square" or "raising to same power"  WILL NOT make the new ratio equivalent.

Tina "raised 6 to 2nd power to get 36" and "raised 8 to 2nd power to get 64". According to the rules, the new ratio won't be equal.

Instead of raising to 2nd power, she could multiply by 2 (both numerator and denominator) to get 12:16. This ratio would have been equal to 6:8.

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.
