Question

Im confusedd, please help??

Answer 1

Answer:  three sets of value show 3 consecutive increases and they could be the intensities during fourth, fifth, and six visits:

• 66%, 69%, 72%;
• 63%, 65%, 67%, and
• 67%, 72%, 77%

Explanation:

1) The program recommends a constant intensity for 3 visits, which is what the table shows:

Day        Intensisty

1             63%

2            equal ⇒ 63%

3            equal ⇒ 63%

2) Hence, you have to determine the valid sets that meet the recommendation for the fourth, fifth, and six visits, which are the next three.

2) For the next three visits, the program recommensd increasing intensities.

There are three options that show 3 consecutive increases; they are:

• 66%, 69%, 72%;
• 63%, 65%, 67%, and
• 67%, 72%, 77%

Therefore, those are the choices that apply.
